Recording artist and master improviser, Walt Weiskopf, presents the simple technique of 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.
This book is a little easier than Weiskopf's masterwork, 'Beyond the Horn', which is great for people looking to get into intervallic improvisation. The exercises are lots of arpeggios, leading tone work in odd intervals, which is useful for general technique and maintenance. I would say that the exercises are what sells this book - they're very useful, and could even make for tunes you could call at gigs.
