īand-in-a-Box was first introduced in 1990 for PC computers and the Atari ST. It can create backgrounds, melodies or solos for almost any chord progressions used in Western popular music, and can play them in any of thousands of different music styles. The software intelligently retrieves and customizes groups of measures that are appropriate for soloing over a particular chord at a selected key and tempo. The developers have enlisted the help of a number of skilled musicians as soloists and sidemen to build huge databases of phrases in many styles of music. The software generates a song played typically by four or five studio musicians whose parts may be then substituted or additional ones added.
The screen resembles a blank page of music. The user inputs four basic keyboard inputs consisting of: chords a key a tempo a musical style.
The software has many capabilities, but perhaps the most remarkable one is enabling a user to create virtually any song and have it played by real musicians (playing real instruments).
Band-in-a-Box is a music creation software package for Windows and macOS produced by PG Music Incorporated in Victoria, British Columbia.
