Hello,
As I understand it, you strive to eliminate all negative tension in the singing C, then play the exercises with the best sound you can, which indeed feel easier.
I could go to the Allegro E Singing C quite fast, but from there I can’t make bad tension go away.
Maybe the exercises are for all levels players, so it might be easy for you and you shouldn’t spend too much time on them, or maybe I’m just wrong !
@Greg it is kind of repetitive, are the master series build on the exact same exercises ?
