Ah.. that's a great book! I remember it from many years ago..

And yes, this is correct.. however, what does the term "jazz eights" mean? It is a strange term.. perhaps it makes more sense in context of what else he was saying...

If you interpret this to mean "swing eights"- the implication is that the first note of a pair of eighth notes is held a little longer (like a quarter note/eighth note triplet feel)..I talk about this more in depth in the swing mastery series.

However, every musician has their own interpretation of feel! Benny Goodman, for example tended to exaggerate the hold on the first eighth note (a more lopsided feel), but trumpeter Kenny Dorham swings with almost even eights, and it swings like crazy!!

Of course, the key for us to learn the subtleties of this feel is to listen, and play along with transcriptions (even learn them from memory) and trying to imitate every rhythmic nuance..
