Shimon has been in development for some years. Recently it has written its own music. Shimon was able to use deep learning techniques to create two 30 second pieces of original music.
Shimon was given a vast amount of musical data: more than 5,000 complete songs,
two million motifs, riffs and short passages of music by researchers at the Georgia Institute of Technology.
As well as the deep learning, Shimon also uses computer vision through a
camera on its robot-head to detect what notes it should be playing. It uses what it learned (which can include melodic, harmonic and
rhythmic patterns) to generate its own personal music based on a
musical seed.
