As a longtime jazz performer 6 nights a week, I have a broad concept of jazz.
For me, jazz is an approach, a way to view, hear, interpret, and appreciate all music.
I can listen to Bach, Jimi Hendrix or Stevie Ray Vaughn, Aretha Franklin, movie scores of Jerry Goldsmith, Bartok, Lutoslawski… you see where I’m going with this?
It’s a way to appreciate good music as a creator, a participant, and audience.
I study contemporary orchestral scores to find the moments most striking to me.
They invariably have an aural feature that stands out, affecting more my right brain conceptual and spatial side more directly than a theoretical working out of a concept.
This is the jazz side of me working.
My interpretation of various musics relies on my developed “6th” sense of the purely musical and the aural performance. I listen to almost everything interpreting it with an appreciation of the timbral qualities, the harmonic melodic and rhythmic components, and its ability to grow and develop.
