I'm not sure if I'm learning a lot. All of the shapes and click locations basically sound the same to me.

Make sure your SoundBlaster16 drivers are loading properly, because I don't think I heard two clicks that sounded the same.

Earlier quoted context omitted.

Do you have a hint on how to find that video?

It’s “The Physics of Dissonance”: https://youtube.com/watch?v=tCsl6ZcY9ag

Wow, thanks for sharing.

The video shows this tool, which has a 3D harmony/dissonance explorer, which can be used as a makeshift musical insturment.

The title alone sounds like this would be interesting, but I'll never know if it is because it has a trackers popup listing thousands of "partners" and a load of "legitimate interest" boxes ticked by default. This is Daily Mail level stuff, immediate back button for me.

I am sorry about that, I thought I removed the consent banner along with the ads completely this morning, then I came back here and realized Google AdSense still had the consent banner published, I forgot to disable it, it doesn't show up to me as I am not EU I guess. Should be gone now, please let me know if something else still shows up.

Much appreciated, and it is indeed very interesting!

This is very fun to play with and design different drums. I was able to make one that had 4 connected but distinct regions giving different pitches, then within each of those regions (which look like 4 lobes of different sizes) where you tap on that region will further change the sound! Then I realized I basically just made a hand pan.

> Pitch here is a reference: the note a circle of this area would sound. Tension and density are yours, and so is fade, which is material and air. Where each shape's own fundamental lands above that reference is not yours, and neither is any overtone ratio. Both are computed.

You might want to do a human editing pass on the copy. This reads like it came right out of your Claude Code session.

Very cool. Number keys and QWERTYU (or clicking the rows on the right) trigger the "modes" in isolation, which are surprisingly microtonal. Also you can draw your own drums! What! That's so cool

there's an amazing video on youtube about how metal bar/gong instruments (like gamelans) have different overtones, and regular western intervals instead of being consonant (like with vibrating strings) are dissonant - even perfect 5ths - and a totally different set of intervals are consonant (slendro and pelog tunings are a bit different for this reason). thinking about it, each drum here would have totally different…

A friend told me that a Dutch university ordered a custom gamelan tuned chromatically. It was a total failure and sounds terrible. The gamelan are made one by one w the oldest member of the group making his first and everyone tuning theirs from his down in turn, IIRC.
