I am continuing to "master' at least one addition Gospel melody as I approach new keys on the Chromatic. Come Thou Fount offers a challenging F3 to practice with in the chorus. Here is the music notation which I generated in Musecore. You will see the F# as we reach "Teach me Some" and "Sung by."
Here is my effort at playing these notes. You will see me switch to the diatonic the 2nd time through.
