This series from Alfred and the National Keyboard workshop reveals all the secrets to playing jazz keyboard. It provides a fun way for the player with intermediate-level or above note-reading and keyboard experience to gain valuable playing and improvisational skills. The "Beginning" book spans the major scale and basic triad theory all the way through 7th chords, pentatonic scales and modulating chord progressions and features a full etude or tune demonstrating every new concept. The "Intermediate" book includes a review of book one, a continuation of modes, chord extensions, making the changes, using chromatic tones and guide tones, chord substitution, "rhythm changes," the blues, altered dominant chords and more. The "Mastering" book starts with a review and quickly moves on to the more advanced concepts of chord voicings, modal soloing, substitution, reharmonization, modes of the minor scales, diminished and whole tone scales, walking bass, stride piano technique, non-diatonic progressions and much more. The optional CD demonstrates examples and gives the student an opportunity to play along.  The optional "Beginning" DVD runs 45 minutes and offers comprehensive instruction so any keyboardist with basic keyboard skills can dig right in and begin learning jazz right away.
