Before I had a routine but sadly as older I get, the routine is more out and instead is what I feel that day. So it's not a must for me to do it everyday. I just think its good sometimes to take the time and feel the notes and how I can control them. Or if I can control them.....
I see some good trombone players here say they dont do it or teach it to their students. Could be ok to listen what all of you think or do? Happy Easter all!
