still thinking about that Duport

I want to extrapolate on my earlier post about Duport's Etude No.7... Teaching a lesson today I realized how unbelievably many aspects of cello technique it teaches: all the different string crossing techniques (both on a slur and separate, every direction and combination), blocking and pivoting techniques in the left hand, elbow adjustments according to whatever the guiding principle is at the time, strength training, speed training...but the best part is that at the end of the day it's still really enjoyable because it's so musical! Can't really say the same about Popper...
