In fact it is that type of jazz that Beato suggest aides in perfect pitch.

It was dedicated to Bill Evans. You can certainly hear a lot of Bill’s influence in Lyle’s playing.

I despise jazz, and have had perfect pitch — both active and passive/relative — at least since high school when my music teacher recognized it.

(I do think you can lose perfect pitch over time, though; I am not confident about that for myself now.)
