Sittin' In with the Big Band, Vol. I is written at the easy to intermediate-easy level. It provides an opportunity to play along with a professional jazz ensemble to improve your playing, whenever you want. As you play with and listen to the outstanding players in the band, you'll learn about blend, style, phrasing, tone, dynamics, technique, articulation, and playing in time, as well as a variety of Latin, swing, ballad and rock styles.
