Playgroup is a practical exercise book for the improvising jazz ensemble, featuring improvisation games that expand creativity while improving the collective time-feel and harmonic and melodic awareness. An introduction and sample exercise from the book can be found here.
Roots Etudes is a collection of etudes for solo saxophone, based on the picking style of roots guitarists such as Mississippi John Hurt and Bob Dylan. These engaging arpeggiated etudes improve one's sense of swing while evening out finger technique, with the added benefit of absorbing blues and "roots" melodic material. A sample etude can be found here.
Many more to come, but to start here are a couple of perfect Lester Young blues choruses that are good for students (or anyone!).
Here is one of a book of Etudes I am working on. The concept is to emulate guitaristic arpeggios in the style of blues/country artists like Mississippi John Hurt, Bob Hadley, and Bob Dylan, and apply these shapes to monophonic saxophone lines.
