Thanks everyone for the suggestions and kind words.
Some details:
The source code for this project can be found on github [0].
I am using an AudioWorklet node with custom DSP using Rust/WebAssembly. Graphics are just done with the Canvas API. The voice leading is done algorithmically using a state machine with some heuristics.
The underlying DSP algorithm is a physical model of the human voice, similar to the model you'd find in Pink Trombone [1], but with some added improvements. The DSP code for that is a small crate [2] I've been working on just for singing synthesizers based on previous work I've done.

95% of the time, I can only get 1 voice at a time. 5% of the time, I can get 2 or 3 voices at a time (1 variable pitch, the others fixed pitch) but I have no idea what input causes this rare behavior. Can you add some help text explaining what various input sequences will achieve?
Android Chrome with touch input (Pixel 8 Pro).
A tutorial would be helpful.
Holding down a note and waiting will cause a second, then a third not to appear. When you move your held, note to another pitch, the other pitches will follow, but with a bit of delay. This produces what is known as staggered voice leading, and produces interesting "in-between" chords.
I've also enjoyed Google's blob opera, for something similar!

And the original singing mouths made by the same guy: https://www.adultswim.com/etcetera/choir/

For years, I've wished someone would port Pink Trombone to a VST or something I could control through code.
Only thing I could find is a Eurorack module: https://blog.bela.io/salt-a-bela-powered-programmable-synth-...
I thought there was some repo public with C++ code, but I can't find it anymore... (https://github.com/belaPlatform)
EDIT: stupid me, it's linked in the article: https://github.com/giuliomoro/pink-trombone
Not to nitpick, but, it being "Arts & Culture" and all, they could've at least said opera aria ...
... not song.-
Not to nitpick but an aria is for one voice.
Add "display:block;" to canvas to fix the issue with vertical scroll appearing. Also, you might want to consider looking into vh and vw units to fill canvas to viewport without using javascript.
Thanks, I'll look into it
Is there a reason to avoid using javascript for canvas layout considering you need javascript to draw on the canvas in the first place?
Very neat. Side note, but one of the more fun aspects of Garageband on the iPad is that you can load string instruments such as an Erhu and play it by physically sliding your finger along the string in a very similar way.
This is awesome fun. Reminds of Google Blog Opera and Pink Trombone.
Can we have multiple voices when using multiple fingers please?
Edit: I can't sing or play music but this is making me feel like I am making someone sing nicely, it's relatively lot easy to play with.
Fun! I'd love the option to increase (double?) range. It would sacrifice precision somewhat, so a toggle would be ideal.
A toggle for quickly visualizing notes would also be useful, as well as keyboard shortcuts — perhaps while one clicks the mouse on a given note, pressing the keyboard shortcut for another specific note gradually moves pitch in that direction, with programmable speed.
Oh, and clicking multiple times at the leftmost portion of the instrument (around 1/4th from the top) sounds exactly like Laurie Anderson's classic "O Superman" :)
Source code is here: https://github.com/PaulBatchelor/Trio
It's written in JavaScript and Rust (compiled to WASM).
This thing is amazing can you add recording?
Perhaps some samples you or visitors create?
Then add a little sampler for beat and it’s a fantastic tool
This is such a great way to practice! Thank you for creating it! Could you perhaps add pitch indicators on the side and multi touch support? Or maybe it's open source?
in Chrome, on my iphone, I can get a cool effect that looks like a glitch, but I wonder if it is a feature. If I hold a note a certain way, where the browser does a “select all”, and then drag my thumb, it drags a thumbnail of the page. When I release it, it keeps the first note and starts a new one using the new position of my thumb. I can create my own harmonies this way instead of the default parts that appear when I hold the note in place.
I'm sorry but I can see a small keyboard with selected notes, can some one describe what makes it 3 parts harmony ? Is it a song thing ? Some chord thing ? There is no description on the site or the github repo.
Does anyone make a USB Midi Theremin? That would totally be the right front end for this one!
Moog does - I've combined it with a midi translator app to customize midi (CC, etc) so that I can use it as an expression input to SWAM physically modeled instruments like violin.

so beautiful. I can imagine using this a lot if some buttons are added (start/stop harmony, view note/resonance, etc). great job
Neat!
