This music was composed by AI with deep learning algorithm which used standalone Keras with a Tensorflow 1.14 backend. It was trained by Bach's four-tone chorus dataset of 229 songs and played on LogicPro X.

Using the method of extracting the characteristics of the composer by calculating the probability distribution of the pitch and length of the note that comes after each note.
