I can tell. I'm gifted with that, you know. When I hear that the tempo is slightly off, it's hard for me.
Miles DavisThe music has gotten thick. Guys give me tunes and they're full of chords. I can't play them...I think a movement in jazz is beginning away from the conventional string of chords, and a return to emphasis on melodic rather than harmonic variation. There will be fewer chords but infinite possibilities as to what to do with them.
