I was trained clasically, on a trombone no less. In my own compositions, the folk and blues rythms and phrasing get mixed in with everything I do. It aggravated the hell out of my Jazz teacher when I was doing improve. Just about everything I write ends up being some sort of fusion of big band, blues, early romantic ballads, and depression era american folk songs. It's just my style, I don't try to keep the music I was educated in appart from what I enjoy, I mix and match. Anyone that accuses you of classical phrasing or predictable chord structures needs to bugger off, nothing should interfere with your style but your own opinions.
