Hexatonics, Vol. 7 (book & CD) (Inside Improvisation Series, Volume 7). By Jerry Bergonzi. Book and CD. Published by Advance Music (AV.14268).
Hexatonic scales are six note scales. This book presents a practical method for the construction of hexatonic scales that are useful for both the improviser and composer. Many modern piano players use hexatonic voicings by stacking the triads to create a particular harmony. We improvise "in" the sound of the voicing and using hexatonic voicings and lines can lend a very contemporary sound. As with the other books in this series, there is a play along CD to try out all of these different sounds. If you liked checking out Pentatonic, you'll have fun with Hexatonics. Good Luck!
