Orpheus/en

Orpheus is a system and a service that automatically compose songs.

Input lyrics, edit settings on its structure, rhythm or chord progression, and the computer will generate a song that matches the lyrics.

Since it was easy to use (you can click a button and make a song), convenient (you can not only listen to the song but also download mp3 / midi), and versatile (change settings and you can make songs with a variety of moods and quality), many used it to create hundreds of songs after it became famous in Nan-J.

It works by "analyzing the rhythm and pitch, and finding the melody that sounds the most natural."
