Tonalis is a new concept in music software. It performs four part harmonisation in the common practise period style.

Enter in a melody and Tonalis will compute the bass-line, alto, and tenor parts automatically. The progressions can be optimised to provide contrary motion between bass and melody and to minimise inner part movement.

Singers and songwriters may find the software useful in aiding their compositional process. Anyone can instantly produce original compositions.

There is a selection of instruments for playing back your compositions. One may export the results as scores or MIDI files.

Requirements: Mac OS X 10.6 or later, 64-bit processor
