How Can I keep From Singing (chrom) Harmonica Tabs

19th C. Quaker Hymn
Key: E
Time: 3/4

-4 6 -6* 7* 6 -6* 6 5*
My life flows on in end-less song
-4 6 7* -8 7* 7* -6*
A-bove earth’s lam-en-ta-tion
-4 6 -6* 7* 6 -6* 6 5*
I hear the real though far off hymn
5* -4 6 7* -6*-6* 6
That hails a new cre-a-tion
7* -8 -8 -8 7* -6* 7* 6
No storm can shake my in-most calm
-6* 7* 7* 7* -6* 7* -8
While to that rock I’m cling-ing
7* -8 -8 -8 7*-6* 6 5* -4
It sounds an ech- o in my soul
-4 6 -6* 7* -6* -6* 6
How can I keep from sing-ing
