What's the story behind your product?

JJazzLab's answer

As a jazz/funk pianist I have tried most of the auto-accompaniment or backing tracks apps (Band In a Box, etc). They are good indeed and I had some fun at first, but I quickly got frustrated: I missed the intensity dynamics which help develop interesting solos. I was aware that a program will never match a real band, but I had a few ideas how to do better. That’s why I decided to start developing JJazzLab.

  • A smart way to translate guitar chords into piano sheet music with Python
    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 / 12 months ago

  • [D] Is MusicGPT a viable possibility?
    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 .

  • Ask HN: Is there a OS tool which queries MIDI datasets by chord progression/key?
    A little manual, but music21[0] can do the analysis! [0]: http://web.mit.edu/music21/. - Source: Hacker News / over 1 year ago
