I'm working more on practicing very quietly to build my chops, but also to improve my overall playing. When I do this, I'm mostly playing easy tunes or hymns. I practice as quietly as I can (using good breath support) while still keeping a sound going. Most of the time, there is a double buzz going on and some cracked notes. I figure it will get better if I keep working on it. QUESTION: Is this a good approach or should I play a little louder to the point where I can eliminate the double-buzz and cracked notes and then gradually decrease volume/loudness as I get better at it?
