Subtitled "THE MODERN SOUND - A Step Beyond Linear Improvisation", by Walt Weiskopf. Recording artist and master improviser, Walt Weiskopf, presents the simple technique of "triad pairs" (using only two triads) to create long, exciting phrases for all improvisers. You will find yourself suddenly sounding much more hip and "modern" with this technique, and yet it is fairly easy to understand.
Walt explains the technique, and then gives you plenty of material to work on to get this method "under your fingers." This is definitely a recommended book for intermediate or advanced players who are looking for something to help take them to the next level. Use intervallic techniques to expand and enhance your musical performance in whole new directions.
