MyJazzBand is a MIDI jazz accompaniment generation application that incorporates intelligent jazz chord and scale analysis, a modern native Mac OS X Cocoa user interface, Band-in-a-Box file format compatibility, and much more.

Intelligent Jazz chord and Scale Analysis

MyJazzBand applies state-of-the-art, intelligent jazz chord and scale analysis algorithms to generate realistic accompaniments that mimic music played by a real rhythm section.

Native Mac OS X Cocoa User Interface

Its built-in chord editor uses Mac OS X Cocoa features like text completion and input validation for quick and accurate chord entry.

Band-in-a-Box File Format Compatibility

MyJazzBand can import chord sequences from Band-in-a-Box files. This lets you use BIAB files you already have and the large number of BIAB "real-books" you can download from the Internet.
