Exact transcription, as played by Dennis Irwin, plus 21 simple bass lead sheets. See and hear how a well known bass player phrases and articulates and comp for the soloist on the mp3 CD. Play along with one of todays finest, swinging New York rhythm sections: Mike LeDonne on piano, Dennis Irwin on bass, and Kenny Washington on drums. Use the book/CD sets for private lessons, for self-study, or in any combination up to a full jazz ensemble, including flute and clarinet. If you are more advanced you may want to use the book to develop your sight reading abilities, for transcribing the bass lines off the CD (then check against the book) or for just having fun playing along with a great jazz rhythm section. The Jazz Conception Series is also perfectly suited for the class room. It can be used to develop younger students jazz style in a big band or small group. In an improvisation class the teacher can use the etudes as studies in improvisation. The Study Guide provides an analysis of each etude, along with practice assignments for each etude. Please note that mp3 CDs may not work on some (older) CD players.
