BandMaster is a phenomenal tool for improvising musicians of all genres. In essence, it emulates a backing band consisting of bass, drums, and piano on the computer. Using BandMaster couldn't be any easier. Opening an existing song or picking a template for a new one is all that is needed to get started. Settings for count-in, speed, and number of choruses are readily available in the main window, and a familiar set of buttons for play, stop, and pause handles the rest.
