ArtSong is a versatile MIDI-based algorithmic music composition system suitable for both serious composers and casual users.
1. Compose and harmonize melodies.
2. Compose countermelodies and 'counterpoint'.
3. Generate chord progressions.
4. Generate bass parts.
5. Compose chord pads and accompaniment patterns.
6. Control musical form and thematic sequence.
7. Compose a variety of harmonic and rhythmic support parts.

A unique music composition tool that combines algorithmic composition with computer-aided composition techniques. Instead of using traditional music notation to specify musical structures, ArtSong provides algorithmic 'building-blocks'. ArtSong is pure algorithmic with no hidden pre-composed musical sequences so musical decisions are under your control. After you select and configure the algorithmic 'building-blocks' and specify their properties ArtSong's composition engine will implement your decisions. The resulting compositions are your original work. ArtSong is a great tool for composing fractal music, included are chaotic attractor algorithms, fractal image algorithms, and L-System text-string algorithms.
