Diatonic Harmonica Techniques

Tab is short for tablature and is the term you’ll usually see. Tab is a shortcut notation that indicates how to play which hole on the harmonica.  This is different from standard musical notation, which indicates what note to play, including its relative duration.  The difference is between how to play a hole and what note to play.  How to play a note on the harmonica is specified by several things:

  • which hole to play,
  • whether you are inhaling (i.e. drawing) or exhaling (i.e. blowing), and
  • what alteration to apply,
    • be it a bend,
    • overblow,
    • other harp specific effect.

Of course, how to play a note on a harp is equivalent to what note pitch gets played, so tab is a kind of shortcut or aid to standard musical notation.  What tab doesn’t show well is timing and rhythm, which is why standard notation is better for really communicating just how something is supposed to sound. 
Ways to show timing for tab include providing the lyrics, when possible, or indicating the measures (bars) and the beats.  Tab can also be used in conjunction with standard musical notation to augument the standard notation with harmonica-specific techniques and effects.

I have considered several important factors for good tab notation conventions, including:

  • Using standard ASCII characters (instead of arrows or other special graphic characters, as is seen so often) so the tab can be easily typed on a standard keyboard and e-mailed or posted on web pages, etc.
  • Keeping all the characters for a note or chord on the same line, for ease of reading
  • Not using letters like B, D, b, etc., which can be confused with note names
  • Selecting characters that maximize “white space”, which makes the tab easier to scan
  • Minimizing the number of characters needed to specify the way a hole is played
  • Making it as obvious as possible.

Here is the notation I use for describing how to play a hole:

  • Blue Midnight as by Charlie McCoy in his “Tribute to Little Walter”

“Misty” 
Lyrics by Johnny Burke, Music by Erroll Garner

Listen to my version in Real Audio.

verse: 
Look at me, 
 ~4    3   2’… 
I’m as helpless as a  kitten  up a tree,

And I feel like I’m clinging to a cloud;

I can’t un-der-stand, I get misty just holding your hand. (repeat for 2nd)

But it’s just what I want you to do.

That’s why I’m foll-ow-ing you. (DS for 3rd verse) 
9>’       9>’ 8> 10>” 9>’ 8> 8 (fill for turnaround)

I just wanted to add a couple comments about Jerry Portnoy’s rendition of Misty. I heard him do it at SPAH 97, and–despite not being that fond of the song before hand–I was blown away by how great a job that Jerry did. He was so attentive to the details.. rhythmic, pitch–especially on the embarrassingly exposed intermediate bends (3 draw whole step (3″) and 2 draw half step (2′) bend), and tone (see note with pitch). It’s a piece where “the slow” is definitely in evidence, less is more.
His tone on the bends was just killer.. very horn like I thought. It’s great practice for those intermediate bends because:
1)the melody is so well known, you’re familiar with what the note must sound like, and 2)the bends are right out there on important sustained notes.. you’ve got to get them clean and strong and pure. There is also some good work on the top end. The 9 blow bend (9>’) is the key note of the melody on the bridge.. you have it hit it without ever getting the unbent 9 blow.. same with the 10 blow whole step bend (10>”).. but you go from 9>’ to and from 8>, so you’ve got to keep hitting the 9>’ plain, without bending into or out of it.

How to Make Your Own Harp Tab

Here’s a great way to easily make your own harp tab. 

  1. Get the shareware program, Melody Assistant, from http://www.myriad-online.com
    Available in several languages for Mac or PC.
    (1a. If you like it and use it, send them the $20 registration fee. Unbelievably reasonable price.)
  2. Search the web for any MIDI song you like, and download it. 
    There are thousands of MIDI files out there for just about any music style you could want, including blues, jazz, classical, pop, rock, country, hymns, etc.
  3. Open the MIDI file in Melody Assistant, select the part with the melody, and give the “Edit Tab” command.

Melody Assistant offers 3 different harp tab styles (as well as guitar tab), and will optionally optimize for breath direction and show overblows. You can specify the key of the harp, so you can get the tab for any position you want.  Plus, it supports all the standard commercial special tunings, or you can define your own tuning!

Presto! That’s it! Now you’ve got tab for any song you can find in MIDI, in any position, for any tuning of harp!

You can even play the MIDI and follow the tab along with the melody as the song plays. This is a  great way to learn new songs.  There are even options that allow you to color the notes, say making blow notes, draw notes, and bends a different color, making the music easier to read.

AND, you can learn to a*sociate standard notation with the harp tab!  This is a super way to learn how to read standard notation, since the harp tab’s right there with the music notation.  It’s also nice because you can get the timing and rhythm information from the standard notation, and use the tab to get the right pitch.

If you don’t find the MIDI song you want, you can always go buy a book of sheet music, quickly enter in the melody, then use Melody Assistant to generate the harp tab.

Diatonic Harmonica Techniques

This table lists a large variety of techniques that can be used for playing the diatonic harmonica.  These are in some order of difficulty, however even simple techniques can require much practice and expertise to master. The harmonica is sometimes called the easiest instrument to play, but the most difficult to master.  While that is certainly arguable, don’t think that becoming an expert on the harmonica is easy or will happen over night, despite what some book titles might lead you to believe…

This table should give you an idea about “where you are” in your ability, and what techniques you still need to master.

I’ve included sample Real Audio clips to demonstrate most of these techniques, where it makes sense.  Some areas, such as embouchure, should not effect the resulting sound to an appreciable degree.  The samples are most all played on a key of A harp.


Diatonic Harmonica Techniques

Technique
Remarks
Sample
Wow, you can make noise *sucking*
too!
Playing should be done by breathing
through the harmonica
, not by thinking about blowing or
sucking.  We talk about blows and draws, but it’s about inhaling
and exhaling.  The breathing should come from
the diaphragm
.  Breath control is as important in
harmonica
playing as in singing. The air should be slowly inhaled and exhaled.
Practice
playing a note and holding it for as long as you can, being careful not
to get dizzy.  Also practice breathing in as much air as you can..
hold it.. now breathe in a little more, and a little more. 
Practice
breathing in and out as fast as you can–think of a panting dog.
Play
Simple 1st position play (i.e.
“straight
harp”)
Many traditional “camp fire”
songs are easy
for the beginner, like “Oh Susanna”, “Red River Valley”, “Clementine”,
etc.  These are normally played by ear and use 1st position where
the key of the song is the same as the key of the harp.  The
middle
octave is most often used, where a full diatonic scale is available
without
requiring any bends.
Play
Chords and
Chugging Rhythms
The harmonica lets you play
chords as well
as single notes, and the chords are easier to get than single
notes. 
The chords can be used as backing rhythms to compliment melodic
play. 
The tongue block embouchure
is normally used so that chords can be played and then blocked to
produce
single notes.  Chord chugging can make use of rhythmic
breathing patterns
.
Play
Play
Single notesBecause of the close proximity of
the holes
on diatonic harmonicas, some technique and practice is required in
order
to get clean single notes.  The way of putting the mouth on the
harp
is called embouchure, and several
different embouchures can be used to get single notes. The main
embouchures
are the pucker or lip
block
, the tongue block,
and the U-block or slotted tongue.
Play
The 2 drawThe hole-2 draw is often
problematic for
beginners, and sometimes the 1 draw as well.  Many beginners think
there’s something wrong with the harp, because this note won’t
play. 
The usual reason is a “pre-bend” condition where the mouth/vocal tract
shape causes a flatted note or keeps the note from sounding.  The
beginner should concentrate on a mouth shape for making an “eeeee”
sound,
and might want to let a little air in through the nose at first
to help play the note.  If you can draw holes 1-2-3 and hear the 2
draw note, you know the harp is okay.
Play
Hand techniquesCupping
the
harp with the hands
, and opening/closing the hands and fingers is a
common and traditional way to achieve very characteristic harmonica
specific
sounds.  The key is getting a very air-tight cup with the hands,
which
mutes the sound.  Opening and closing this cup creates the
characteristic
“wah-wah” sound of the harmonica.
Play
Multiple key harmonicasDiatonic harmonicas come in all
different
keys (i.e. C, D, E, … Ab, Bb, F#, etc.). The normal range of harps
from
low to high (such as when harps are offered in a set) is G at the low
end
to F# on the high end, but doubled keys add high G and low harps from D
(or even low C). The sample has chords for A, C, and D harps, 3 of the
most common keys.
Play
Note
articulations 
The tongue can be used to start
or attack
notes differently, which changes the color of the notes and adds
variety
to the sound of the harp.  These articulations can be
associated
with various spoken syllables, like saying “ta” or “ka” or “da” or “ha”
or “ga”, etc.  Articulation can also be done by slightly lifting
the
upper lip off the harp and replacing it in a sort of “biting” or
“kissing”
the harp fashion.  Articulations are easiest using the pucker/lip
block embouchure, but can also be done using tongue blocking.
Play
ShakesA shake is a rapid
alternation between
adjacent holes. Shakes are similar to trills, but the notes are more
than
1/2 step apart. Sometimes shakes are called “warbles”.  Shakes are commonly done by shaking the head from
side to side, but can also be done
by moving the harp from side to side, twisting the harp, or some
combination
thereof.  More advanced shakes can incorporate note bending to add
variety.  The samples are from Stormy Sea II.
Play
Play
Play
2nd position
(i.e. “cross harp”)
2nd position is the most commonly
used approach
to playing blues, rock, and country music.  The scale
for 2nd position
is a 5th higher than the natural key of the harp,
for example, for a key of C harp playing it in 2nd position means
playing
in the key of G.  2nd position starts on the 2 draw and uses
mostly
draw notes, especially on the low end of the harp, rather than mostly
blow
notes as in 1st position (the key of the harp).  The draw notes
provide
more possibilities for bends and expressive vibrato than the blow notes.
Play
Draw
Bends

as ornaments 
When beginners first achieve draw
bends,
which are available on holes 1-6, they are primarily quick changes from
the natural note, like a quick flattening of a note continuously
bending
a little down and then back up to the primary note.  In other
words,
the bent notes are not used as notes in their own right.  The note
bends, but the player has little control over the depth and duration or
the note. The sample has a thin weak sounding draw bend, and is an
example
of what NOT to do.
Play
Blow Bends as ornamentsBlow bends are available on holes
7-10. 
The sample has a thin weak sounding blow bend, and is an example of
what
NOT to do.
Play
Dip bendA dip bend is a quick smooth bend into the note to be
played. 
This technique is frequently used to ornament notes, especially on the
draw notes.  It is done by initially attacking the hole as a bent
note, then gradually releasing the bend to slide into the final
note. 
Or, the hole can be started unbent, and a smooth gradual
bend can be used to slide into the final bent note.  The sample
clip
is from Stormy Sea II.
Play
GlissandoA glissando is a sequence of notes played in rapid succession
that
ends on the primary note to be played.  Play a single note and
then
slide the harp around in your mouth.. that is essentially a
glissando. 
The notes in a glissando are not individually articulated, but are
played
as a single continuous physical movement.  A “ripped” glissando is
essentially an articulation of the final note.  The sample clip is
from Stormy Sea II.
Play
Diaphragm
Tremolo
Diaphragm tremolo is distinct
from throat
vibrato
, and as its name implies it emphasizes the diaphragm
instead
of the throat, though each is used to a certain degree. It is
characterized
by a volume oscillation tremolo as opposed to a pitch oscillation
vibrato. 
However, when using vibrato on a held bend, the diaphram is used to
gently
add the tremolo, and the pitch will vary due to the pressure changes.
Diaphragm
tremolo is basically achieved by repeating “ha ha ha ha” as when making
a laughing sound.  The sample tremolo is somewhat exaggerated so
you
can easily hear it.  Often the term vibrato is used instead of
tremolo
to mean either vibrato or tremolo.
Play
Draw
Bends

for note production:
– Full bends 
– Intermediate Bends
Draw note alterations are
so-called
bends that alter the natural pitch of a note to a different usable
on-pitch
note. The word “bend” implies a continuous pitch change, but bends on
the
harmonica do not have to be changes from other notes–in other words, a
bend as an altered note can be played separately from other notes, and
the natural note need not be played at all.  Draw bends in holes 2
and 3 have bend ranges more than a single half step (semi-tone), while
draw bends in holes 1, 4, and 6 have a half step range.  Bends
tend
to alter most easily to the extreme range, called a full bend,
and
notes between the natural note and the most altered note are called intermediate
bends,
and are more difficult to achieve, control, and maintain on
pitch than normal bends.  The sample has a number of draw bend
notes
mixed in with normal notes.
Play
Blow Bends for note
production 
Holes 8 and 9 have a half step
blow bend,
while hole 10 has a whole-step bending range.
Play
Rhythm and melody together (i.e. vamping)Using a tongue
blocking
technique, rhythm chords and melody can be played at the
same
time.  Normally a chord containing the melody note is played, and
then notes of the chord are blocked from being played by using the
tongue. 
Similar effects can be achieved with a lip block by opening and closing
the embouchure or rolling the harp up at the back to go from a chord to
a single note.  This technique is often used on the bottom 3 holes
where lip blocking is more difficult.
Play
Playing from a RackA rack is a device that holds the harp so you can
play hands-free. 
Usually the rack goes around your neck.  Often a “wing nut” is
used
to hold the rack tight at a pivot point, and often the rack will slip
and
push away from your mouth.  Using two conical washers or a lock
washer
can help keep the rack tighter.
n/a
Amplified
play
Traditional blues style harp is
played amplified
through a microphone

The mic and the amp work together to produce the sound, and what you
should
get depends on what you like to hear.  Traditional mic’s are
bullet
shaped vintage or vintage reissued models like the Shure
Green Bullet, Astatic JT30
, Hohner Blues Blaster, etc., though
many
players use ordinary vocal mics such as the Shure SM-57 and
SM-58. 
The Shaker brand mics are smaller, lighter and easier to cup than
traditional
bullet style mics  Tie clip electret mics can also be used, and
these
are easier to cup tightly and produce acoustic-style hand effects. Preferred amplifiers
are normally tube amps
, and vintage
Fender
amps are highly valued as harp amps.  Popular amps include the
Fender
Bassman, the Bassman ReIssue (RI), the Fender Champ, Fender Princeton,
etc.  Many players prefer amps with reverb, or use separate reverb
“tanks”.  Digital or analog delay pedals are a common effect in
amplified
play.
Play
Slurs and
double stops
A slur is where a bit of
an adjacent
note is played along with the primary note.  A double stop
is where two notes are played at the same time with essentially equal
strength. 
Double stops can be played using bent notes and combinations of bent
and
un-bent natural notes, especially on holes 1-4.  It is even
possible
to play an overblow so that both reeds sound and two notes are
generated. 
A slur has a primary note and a softer secondary note. Slurs can add a
“bite” to a note, especially when amplified.  When playing 2 notes
together think about 1)Blending the sound or 2)giving each note its own
voice.  The sample has first a slur, then a double stop for the
same
notes. Notice how much smoother the slur sounds.
Play
Split Intervals 
– 4-hole octaves 
– 5-hole octaves
Split intervals are notes
that are
played that have intervening notes blocked out, normally by the tongue.
The most common split interval is an octave, for example holes 1 and 4
blow or draw at the same time, with the tongue blocking out holes 2 and
3.  Hole 4 and 8 draw also form an octave, with holes 5, 6, and 7
blocked out.  The sample plays single notes an octave apart, then
together, for both blow and draw octaves.
Play
Octave ShakesAn octave split interval is played and rapidly alternated
with an adjacent
octave, as in a 2-hole shake with single notes, by shaking the head
and/or
harp.  This effect is heard relatively infrequently on the
diatonic,
but was used by classic blues harpers like Little Walter on songs like
“Blues With A Feeling” and “Got My Mojo Working”.  This is a
commonly
used effect on blues chromatic, and the sample is played on a Hohner
Super
64X.
Play
Resonance 
Vocal tract
– Hands/cup
Resonance is a
reinforcing
of sound waves that amplifies a note.
  Achieving good tone
on a harmonica requires resonance, and tuning the vocal tract to the
note
being played.  This requires opening the vocal tract and playing
“from the diaphragm”
. Hand resonance can add to the player’s vocal
tract resonance and further amplify a note.  Very minute changes
to
the hand cup can produce or eliminate this resonance. The samples were
played with the same force of breath.  The differences in volume
are
due to the added resonance.  Notice how the tone goes from thin
and
weak to full and strong.
Play
Play
VibratoThroat vibrato is a slight
wavering of a
note’s pitch similar to the effect singers use. Throat vibrato, as
distinct
from diaphragm tremolo, is mainly
felt
in the throat as a pinching of the air stream.  In reality both
throat
vibrato and diaphragm tremolo use elements of both the throat and the
diaphragm,
but the emphasis is different as the names imply.  Throat
vibrato is a very important technique that should be learned by
everyone.
 
It is very frequently used and adds much to the tone
and note shaping capabilities of the harp.  There are other types
of vibrato that can be achieved by moving the mouth or the lips. 
A slight chewing motion, or chin vibration produces a kind of vibrato,
as does a motion similar to whistling a vibrato.  Similar vibratos
can be achieved by articulating “oy oy oy” or “yo yo yo”.  These
non-throat-vibrato techniques are especially useful on bends and
overbends, as well as notes that don’t respond as well to throat
vibrato.
Play
Tongue SlapA tongue slap is a
technique where
a chord is played for a brief time, then all but one or two notes are
suddenly
blocked out with the tongue.  The air that had been flowing
through
normally 4 holes is suddenly diverted to 1 or 2 holes, and the sudden
blocking
of 2 or 3 holes causes a kind of slapping sound.  The sample is
exaggerated
to highlight the effect. The tongue slap is one of the characteristic
techniques
often used with the tongue block embouchure, and serves to thicken up
the
sound of the harp and punctuate single notes.
Play
Flutter
tongue/tongue
lift effects (i.e. rapid vamping)
A flutter tongue or rapid
vamping
technique
is where (normally) a split interval is played and the tongue is
rapidly
and repeatedly removed and replaced off and back onto the blocked
notes. 
It causes a rapid switching between a chord and an interval like an
octave,
or even a single note.  The sample first plays an octave slap,
then
the rapid alteration between a chord and the octave, for both blow and
draw.
Play
Tongue Rolls A tongue roll is where a note is
played and
the tongue is vibrated or rolled as in a Spanish-style rolled-R. 
This is a seldom used effect more than a normal playing technique.
Play
WhoopsA “whoop” is using your voice to
whoop or
holler while playing the harp. This is normally a seldom used effect
rather
than a standard playing technique. You can also do barks, clicks, and
other
mouth or voice effects in conjunction with playing the harp. 
Sonny
Terry and Peter “Madcat” Ruth make frequent use of this kind of effect.
Play
GrowlA growl is an effect used in
conjunction
with deep draw bends. The soft palette at the back of the mouth is
relaxed
and allowed to vibrate; it’s kind of like snoring while playing. 
This vibration along with the bent note causes the growl sound.
Play
Back-Pressure ChordsBy using a very air tight hand cup it is possible to play the
harmonica
backwards, by having air enter through the back of the harp in addition
to through the front.  In essence, your cup is so tight that when
you play a note the air pressure builds up in your hand cup and flows
back
into the harp.  Similarly, a draw note causes enough of a vaccuum
to suck air into the harp through other non-played holes.  You
block
the holes you don’t want to sound with your thumb or finger and use the
back-pressure activated notes along with the played note to create new
chords.
Play
3rd position
(i.e. “draw harp”)
As 2nd position is playing in a
key a 5th
above the natural key of the harp, 3rd position is playing in a key
another
5th higher than the natural key of the harp, e.g. for a key of C harp,
2nd position is the key of G, and 3rd position is D. 3rd position play
starts on the hole 1 or 4 draw. The natural mode of 3rd position is a
minor
key so 3rd position is often used to play with minor key songs.  A
complete 3rd position blues
scale

is available on the first two octaves, so this is a common position for
blues next to only 2nd position in frequency of use.  The sample
is
the blues scale in 3rd position.
Play
Knowing where you areBeginners usually don’t know
right where they are on the harp at all times, while expert players
usually do.  As you gain more techniques like bends and overbends,
it becomes important from a technique standpoint (separate from a
musical standpoint) to know where you are because each hole plays
differently; some bend well, some don’t, some bend more or less than
others, some are draw bends and others are blow bends, some holes are
good for overbends and others not so much.  Musically, you need to
know what note you’re on, and where the other notes are.  You need
to become extremely familiar with the harp note layout, both within a
hole and across the harp.
Able to go where you wantOnce you know where you are, you
need to be able to visualize where you want to go, and you need to be
able to get there accurately.  This is more difficult when you are
going to holes not adjacent to the current one.  Corner switching
from a tongue block embouchure can make octave jumps and other
intervals easier to hit accurately than pucker/lip-blocking since the
mouth doesn’t have to move far because the tongue is moving too.
Playing both ends of the harpThere are usually 2 different
octaves (sometimes 3) where you can start playing your song, lick,
riff, or phrase…the bottom end and the top end.  You should be
able to play the same thing starting in different octaves, as long as
you don’t run out of harp.
Special Tunings Special tunings are modifications
to the
standard diatonic layout of notes, which is the Richter
tuning. 
Common special tunings include the natural minor, which provides a
minor
key for normal 1st and 2nd position playing, the Lee Oskar Melody
Maker,
which raises the b7ths (i.e. hole 5 draw) to Maj7th and raises hole 3
blow
a whole step, Steve Baker Specials which adds a duplicate of the low 3
holes as the 1st 3 holes an octave lower, country tuning, etc. etc.
These
special tunings make playing certain styles easier than using normal
Richter
tunings. The sample has chords from a Melody Maker tuning, a Natural
Minor
tuning, and a rare tuning called Tempting.
Play
Train
Songs
Train songs use train-like
rhythms on chords
on the low 3 holes, and work best on lower key harps (like G and
lower).
A train whistle is simulated by drawing holes 3 and 4 at the same
time. 
One articulation that mimics a train is “Tah hooka tooka hooka” where
only
the “hooka” is played exhaling, and many variations on that theme, like
“Tooka hooka tah hooka”.  Other fast tongue articulations can be
used
to augment the breathing pattern,
such as “diddly hooka diddly hooka tah hooka diddly hooka”.
Play
Multiple EmbouchuresThe 3 primary embouchures
are the puker/lip block, the tongue block, and the (relatively seldom
used)
U-block. The lip block and tongue block can be used for different
effects,
so it is good to learn and use both and be able to switch back and
forth
easily depending of the effect you want.  Many players believe the
best blues tone can only be achieved by using the tongue block. 
Many
effects and techniques require use of the tongue block embouchure.
Subtle effect on player’s tone
Playing out of both corners (of
the mouth);
TB left and right
Tongue blocking is typically done
with the
tongue blocking holes on the left with the single note being played by
the right corner of the mouth.  It is also useful to be able to
block
on the right and play out of the left corner, for fast accurate note
jumps
(corner switching) and playing holes 1-3.
It’s how, not what you hear
Bends from all embouchures and
corners
Many players bend from one
embouchure, like
a pucker/lip block, and not from another, like the tongue block. 
It is best to be able to bend from all the different embouchures and
both
sides of the mouth.
It’s how, not what you hear
Split interval bendsIt is possible to bend both
notes of a split interval, e.g. an octave, at the same time.  You
can also bend one note of an interval to form an octave, for example
the 3 draw whole step bend (3″) and the 6 draw.
Tongue
Switch Shimmer 
The tongue switch shimmer is an
effect where
the tongue is rapidly switched from side to side to allow opposite
corner
holes to sound.  This can be done extremely rapidly.
Play
Draw Bend VibratoGetting a smooth vibrato
on draw bends requires a delicate control and balance between the
throat
and the diaphragm. Without this delicate control the vibrato becomes
very
chunky.  The sample is a hole 2 half step “intermediate” bend.
Play
Blow Bend VibratoBlow bend vibrato also requires a
more delicate
control than vibrato on straight “unbent” notes.
 Play
SpeedSpeed playing requires note and
rhythmic
accuracy and control of rapid changes to breath direction.  It is
easy to overuse speed, which can detract from musical expression. 
The sample is a clip from Stormy Sea II.
Play
12th Position12th position (sometimes called
“1st flat”) is the key with one more flat than the key of the harp, or
equivalently a 4th above the key of the harp.  For example, on an
F harp 12th position is the key of Bb.  12th position is useful
for melodic play in a major key. To play 12th on the bottom of the harp
you need to be very good at the 2 draw whole step bend and the 3 draw
whole step bend.
Positions
4-12
Learning positions 4-12 requires
additional
familiarity with the diatonic note layout.  The natural scales
associated
with position play correspond to various modes.  Best use of these
positions requires the ability to play chromatically by using either valves
or overblows.  5th and 12th
positions
are particularly useful.
n/a
No speed neededSometimes speed can be used as a
crutch to
hide defects in playing. Attention to details and nuance of note
formation, tone,
timing, and phrasing can require more expertise than merely playing
fast. 
Details and mistakes are more exposed during slow play than during fast
passages.  Speed is best when the precision and nuances required
for
beautiful slow play are incorporated in the fast passages as
well. 
The sample is a clip from Misty.
Play
Valved
Bends
Valved bends use only a single
reed for the
bend, rather than both reeds as in a  normal diatonic bend. 
Valved bends have a greater potential range than normal bends, but
require
a different attack and bending approach.
Play
Overbends
(i.e.
overblows and overdraws)
Overblows and overdraws activate
the opposite-than-normal
reed as an opening reed as opposed to the normal closing
reed activation.  Overblows activate the outer “draw” reeds to a
note
about 1/2 step above the natural draw note, while overdraws activate
the
inner “blow” reeds to a note about 1/2 step above the natural blow
note.
Overblows require relatively narrow or tight reed
gaps
.  Achieving overbends requires much more focus and
finesse
than ordinary bends, with much stricter requirements on mouth/throat
shape
and pressure.
Play
Bending overbends and overbend
vibrato
It is possible to bend the pitch
of overblows
and overdraws, and add effects such as vibrato
to the overbends.  Overbends themselves require much greater
facility
with the harp than normal bends, and further bends and effects require
still greater control and expertise.  The first sample for bending
an overblow (hole 6) is a clip from Stormy Sea II on a C “Golden
Melody”. 
The second sample is a hole 7 overdraw with vibrato followed by a 7
blow
with vibrato.

Play
Chromatic playBy using overbends and/or valved
(isolated
reed) bends in addition to normal bends and the natural notes it is
possible
to play every note on a diatonic harp, that is, to play a diatonic
chromatically. 
This adds enormous capability to the diatonic and especially position
play. 
However, it is extremely difficult to get tonal or timbral consistency
between unbent, bent, and overbent notes.
See “Jazz” sample
JazzThe ability to play the diatonic
chromatically
brings jazz into the realm of the diatonic.  Jazz is a difficult
genre
on any instrument, and especially so on an instrument such as the
diatonic
that requires advanced techniques to make available all the chromatic
notes. 
The sample is the song Blue Monk using a normal and a low Eb, 2nd
position.
Play
CounterpointCounterpoint is more than one
melody at the
same time. By sophisticated use of single notes, double-stops, playing
out of both sides of the mouth, and split intervals, simultaneous
melodies
can be played on the diatonic harp.  Diatonics have one advantage
over chromatics in this area because wider splits are possible due to
the
smaller hole size of diatonics as compared to chromatics.  Special
tuned harps are often used for counterpoint play.
Listen to Richard Hunter

Chromatic play in all keysSince a single diatonic harmonica
has all
chromatic notes available (though some have a different timbre than natural notes), it is possible to play every key diatonic in
every key.  This of course requires a great deal of practice and
study.. very few can do it.
