I built a tool where music becomes geometry… is this useful or just cool?

I’ve developed a free web app: https://erhythm.org/ (disclosure: I’m the developer). It’s a visual, interactive rhythm composer inspired by Godfried Toussaint’s The Geometry of Musical Rhythm. The idea is to represent rhythm geometrically: you place beats on a circle, the active steps form shapes, and you can instantly hear the result.

This is not intended as a learning system or replacement for notation, but as a visual presentation tool for rhythm, to explore and illustrate patterns like Euclidean rhythms, polyrhythms, and world rhythms in a more intuitive visual form.

Example (Bembé Afro-Cuban rhythm):

I’d really appreciate feedback from musicians and educators on whether this kind of visual representation is useful for explaining or presenting rhythmic structures.

    I've explored the rhythms so far and it sounds really good.
    I used to be a session drummer back in the day.
    I like the visual aspect a lot, it's a different way of looking at rhythms especially as I don't read traditional notation.

    Well done.

    Thanks a lot @Gravitas ! I'm glad the visual approach resonates with you.
    Enjoy the app.

    I could play with this kind of thing all day and all night. I love stacking rhythms, rotating them relative to each other to create new combinations, etc. I think your app is great! Thank you!

    This being LP Forum, I have to ask: how soon will it be in the app store as an AUV3 with MIDI out? (50% kidding, 50% hopeful)

    Thanks @daddyfalldown , I'm really glad you're enjoying it! As for the AUV3 with MIDI out, I'll add it to my TODO list for a future update.

    Sweet, cause the only app i know of that did this was the now defunct app, Aphelian.

    4Pocket’s AU3 Euclidean Sequencer comes close, but you have to imagine the shapes. In other words, the circle and points are there, you just need to envision the lines.
    And if you’re into the educational part, the app also contains great documentation on the different claves, ect. The app isn’t exclusive to just Euclidean.

    I read that book geometry of rhythm with great interest, and you made a fantastic web app to capture those diagrams (and there’s plenty in the book). Very fun to play with, really nice work, and I guess the next logical step would indeed be for it to output midi. Not sure if it can be done from a webapp (webmidi perhaps? Not sure safari supports it)
    Anyway keep up the good work and thanks for the share

    Thanks @Blipsford_Baubie for mentioning those! I'll definitely check them out. I particularly like the idea of combining rhythm generation with educational content, it would be great to make these patterns more accessible and explorable.

    Thank you @pedro ! Really glad you enjoyed both the book and the app.

    Yes, MIDI output is definitely possible from a web app using WebMIDI (with some browser limitations, especially Safari as you mentioned), and it's already implimented in my web app

    Appreciate the encouragement!
