Adjusting the Cello Endpin
Here are a few of suggestions for setting the endpin length:
1) Set the endpin to a length equal to span of students hand (tip of thumb to tip of pinkie when spreading hand as far as possible), plus the length of the pinkie (This is an approximate starting point).
2) Ask the student to hold the cello between the knees with knees on lower bouts, then lower the endpin until it reaches the floor.
3) Cello should be about chin height when student stands.
4) C peg should be across from left ear when endpin is correct length.
