A combination of music and programming can be unusual during the past days for having music as a much more perceptual and emotional carrier in the long run of human consciousness. The advantage in computations and the power of execution from programming languages push further apart as being the opposed extreme between perception and rationality distributed on either side of the cerebral hemisphere. Thus, the collision can be exciting. The project is designated to try to understand the music melody through the composition of notes, chords, and chord progressions from a computational process. And by innovating a matching recognition of patterns and similarities, predictions of the related chord presented should help music performers have a more intelligent and convenient playing experience.
