Band-in-a-Box is so easy to use!
Just type in the chords for any song using standard chord symbols (like C, Fm7, or C13b9), choose the style you’d like, and Band-in-a-Box does the rest, automatically generating a complete professional-quality arrangement of piano, bass, drums, guitar, and strings or horns in a wide variety of popular styles. Live audio tracks can be created using RealDrums and RealTracks.
