Fantastic, Bernie! I play on a key of C chromatic quite a bit, although my preference is an A chromatic, as well
as other keyed chromatics, such as Bb, Eb, Tenor C and even a B (among others here and there, but mostly the A).
It IS a breakthrough and an 'aha' moment when you hear the sound in your head and get it right away on
your chromatic. To me that is 'playing by ear', but just the hearing of it in your head is a huge step...and is thrilling
for me to have other people say they're doing what I've always done. It makes me less weird and I LOVE it!
