I chose Python as a programming language here because, as you could probably guess, there are myriads of libraries in Python for working with music. I found mingus to be the simplest for working with guitar chords and music21 for generating the piano score. It might be possible though to do everything with music21 only, because it's extremely powerful, but I found mixing the two libraries to be easier than... - Source: dev.to / about 1 year ago

If you are interested in doing anything with Python, be sure to check out Music21, which has a lot of cool features — including doing twelve-tone matrix stuff like this — built-in. Source: about 1 year ago

It's definitely a viable possiblity, and there's quite a few companeis already doing it. If you want to explore doing it yourself, I'd check out https://web.mit.edu/music21/ and build some basic models using LSTM etc. To have some fun using open source MIDI data sets like https://magenta.tensorflow.org/datasets/maestro .
