Hi I can only help you with the treble cleft side as I play the flute
C E G E D F A F E G B G
F A C A G B D B F C E C
B D F D C E G E C G E C E
F D B D E C A C D B G B

EVERY GOOD BOY DOES FINE going UP the staff, so from the bottom to the top
and the spaces between going from the bottom up represented FACE

I believe it's Bach, he had many sons that went on to be musicians as well.
