Duets are a great way to learn the many skills necessary to become a successful musician. In jazz, duets are especially effective when performed or practiced with a rhythm section. These duets include a variety of styles, tempos and harmonic progressions and can all be performed with the published rhythm section parts or downloadable mp3 tracks. The parts are fully interchangeable and can be played with any combination of two horns and rhythm section. Practice options include: a single player can play either duet part while the mp3 plays the other part; two players can play both parts along with the recorded or live rhythm section; and a single player can work on improvisation with the mp3 tracks or live rhythm section. Additionally, a full online performance track is available for listening purposes. The Power of Two is an exciting way to teach jazz to developing jazz musicians!
