PG Music Inc. is a Canadian music software developer founded in 1988 by Dr. Peter Gannon and headquartered in Victoria, British Columbia. The company is best known for Band-in-a-Box, an automatic accompaniment and song-creation program that generates backing tracks from a user-entered chord chart, key, tempo, and style. Available for both Windows and macOS, Band-in-a-Box has become a long-running staple for songwriters, jazz players, and music educators looking to practice, sketch arrangements, or generate full-band demos.

Alongside Band-in-a-Box, PG Music develops RealBand, a multi-track sequencing and audio environment that shares Band-in-a-Box's style engine, and PowerTracks Pro Audio, a MIDI and digital audio workstation. A major shift in the product line came with the introduction of RealDrums and RealTracks, libraries of recordings by session musicians that replaced earlier MIDI-based playback with audio performances that can be transposed and re-styled to fit a user's chord progression. The catalog has since expanded to include add-on style packs such as Xtra Styles, MultiStyles, XPro Styles, and Loops-with-Style, plus a Band-in-a-Box DAW plugin for use inside hosts like Pro Tools, Logic, and Cubase.

PG Music's niche sits at the intersection of composition tool, practice partner, and production utility. The software is widely used by hobbyists working out song ideas, by jazz and instrumental players generating play-along tracks for improvisation, and by educators demonstrating harmonic and stylistic concepts. Annual versioned releases, a large user forum, and a deep back-catalog of styles have given the product an unusually loyal community across decades of PC and Mac music-making.

PG Music has 8 products cataloged on Equipboard, including DAW Software and Virtual Instrument. Their gear is featured by 1 artist, with the strongest followings in Electronic. Notable users include EatMe.
