I have thoughts about this pedagologically. I think these kinds of tools can be helpful, but the number of rhythm students I have seen who need to break out of the dependence on a visual metronome is rough.
Part of the struggle is really listening to yourself, and learning how to pick up on your own mistakes.
I hope the tool is helpful, and I hope I don't sound too curmudgeonly when I say don't let the time making and maintaining tools for practice detract from the most important thing, the ur-tool of all learning: more practice.

Makes sense! You can enable mini mode (top right) so that you can sing without the pitch track and program at the same time :D... then listen back to your take along with the original and see how you're tracking score wise.

Singing is about so much more than just hitting the right notes. Breath management is one of the most important skills you can develop to improve your singing. Proper vocal technique helps you avoid injuring your voice when tackling difficult songs. Learning to recognize and use techniques like belting, twang, head voice, chest voice, vocal fry, etc., can really bring your singing to life. Prosody and rhythm training help you develop good timing (one of the most important aspects of music), and there's so much more to it.
This kind of app is great for getting started and getting a taste of what singing involves, but it would be awesome to cover these other aspects as well, or at least mention their existence for aspiring singers.

I've been doing classes for more than a year with an online teacher and it's been amazing and when watching the demo I saw so many of the mistakes I've done in the past and yet the app keeps saying to the singer GREAT and PERFECT but the coordination is all over the place, not to mention an octave lower and in a very monotone way (lack of prosody or emotions).
And it makes sense, you can't add emotions until you cover some of the basics.
This app can work really well once you have breath and placement nailed down and you just want to focus on pitch, but it feels like it can me misleading to people to think they sing good.

I like Dan Callaway on YouTube. Jeff Rolka is another good teacher. However, singing is complicated and choosing which exercises you'll use to teach folks ... You need 1. Vowel alignment 2. Coordination of voices 3. Breath support and vocal tension management 4. Mouth shape, tongue placement.
And then there's "how to read a song", deciding which words are emphasized, where to breathe, modifications to fit your voice, etc.

If you're willing to elaborate - For what goals and stages, do you require these?

Background to my question: I was looking for music teachers for myself and my kids (guitar and piano), and I found two types:
1. Royal Conservatory Curriculum, Lesson 1, Page 1, firmly, formally, and without deviation: You MUST learn notation, theory, and proper everything, first. THEN, 5 years later, you get to have fun :)
2. Let's have fun! If you like it and stick with it, we can tackle advanced topics in a customized manner and see where it takes us :)
I find approach #1 is only valid for people who know they will go far and stick with it (either because their parents force them, or for some other, rare, intrinsic motivation); but it hugely discourages huge number of people who don't have such long-term motivation and dedication yet - it postpones the rewards and makes the initial curve super steep.
So my question is: For a completely casual, random person who sings terribly and wants to get "a little bit less embarrassing / dip their toes"; isn't pitch training usually the first step for them to enable their hearing, rather than the complex vocal techniques?
fg137 26 minutes ago [-]
I doubt you'll get an answer here, and people in "type 1" don't want to talk about type 2.
My take, without directly addressing your questions: "have fun" doesn't go very far, and you'll discover that if you want to be good at anything, you'll need to put in many hours of practice with endless repetition and go through setbacks and self doubt, none of which is fun. And for sure there are singers and musicians that never go through formal training, including at the highest levels, they are few, when most musicians you know have been learning music since they were kids.

I understand that being sharp or flat from a target note is called being off-key but I'm wondering where that came from? In my head, off-key would indicate that you are singing or playing a note that isn't the key of the piece (like A♯ if you are in the key of C).
I started thinking about this when trying to play along with stuff on YouTube and discovering that the entire song is sharp (likely sped up during mixing or mastering). Would you describe those songs as being off-key?

You built the scoring feature of karaoke that I failed to build a few years ago, this is awesome!
If you haven't done any karaoke using DAM/JoySound, etc they have a scoring mode that sits at the top that does two things: one, help you sing on key because we all suck, and two, score then rank you against other singers (anonymously.)
I couldn't tell from the demo, but do you get access to the audio ahead of time? My karaoke project stopped in its tracks because I couldn't afford to secure rights to music and there didn't seem to be a great legal solution to get audio.
dsmurrell 1 hours ago [-]
Thanks!
OnKey only listens to what you play through your other apps, then it uses what it's heard to learn the notes and then discards the song and never saves it to disk.
This means that you need to let it listen to the song the first time it plays. You can sing to that song blind (no pitch track) and it will still score you at the end.
What I do is let it listen while a playlist plays through, then when I re-listen it lines up the pitch track with the music as it plays through my music source again.
IANAL, but I think that by listening to the music that people already have access to through their subscriptions, not distributing any music, lyrics, or learned melodies i.e. keeping everything for personal use only (see https://github.com/dsmurrell/onkey#using-onkey-fairly), rights aren't required.
I might do the ranking thing later but this brings some form of centralisation to the project which it currently doesn't have, and I haven't worked out how to stop people gaming that.

You're not wrong. I do have a coding background which helps but I'm new to Rust. It started in Python with a web frontend so it somewhat evolved into this.
> why is it using webview/tauri?
Using these makes it easier to port to the other platforms later if I choose to.
About 365 of the 420 MB is the AI models which I decided to bundle so that the app wouldn't have to download additional things after the install.
My agent tells me that writing in native Swift would save (estimate) about 100–170 MB, out of about 1.4 GB when the models are active. And then I'd have to maintain the interface in two or three ways if I decided to make versions for other platforms.
If it does grow though and there are a lot of Mac users, this might be worth it though as you suggest. But I have a lot of project that go precisely nowhere so I always keep this in mind :)

Yes, this was me. My confidence has improved through practise to a point where it only half killed me to post that demo video. My family still ask me to relocate when I'm doing this around them... so I think you can hit the pitches and still not sound amazing.
Unfortunately, the way it works, and to avoid any copyright issues, it can't really operate on phones because you can't listen to other apps on them. Maybe the only way is to share your learnt pitch tracks (trained on the laptop) with a mobile companion app.

Each song has a difficulty rating from 1 to 5. You can use this to filter your library.
And you can track your scores over the takes you did of a sing in your history. So I think OnKey has you covered on these.
Let me know if it matches what you expect when you try it out.
pheraph 9 hours ago [-]
Awesome, I'm checking it out right now. Just a few quick notes:
- By “difficulty,” I meant that you can set a skill level that's a bit more forgiving if you miss the mark, as opposed to a “pro” level, which may be stricter. I’m thinking especially of kids, who might have more fun with it that way. It would also be nice to have a personal profile to choose from, with your own library (?) or at least your own presets (difficulty, progress, etc.).
- It took me a little while to figure out how the app works. You start a song in Apple Music, and the app records it. I had somehow expected a large search bar in the app that I could use aside from the music suggestions to get started.
- Even though I hadn’t set up Spotify (it wasn’t even displayed), it was still enabled in the settings.
- This is probably a bit outside your scope, but in the german song “An Tagen wie diesen, Die Toten Hosen” some (final) syllables get cut off, and sometimes the bars go down even though the melody goes up (or are the notes transposed an octave when they no longer fit within the scale?).
That's for now, I’ll keep an eye on the project and create issues if my observations become more consistent. Thanks for the project!
dsmurrell 9 hours ago [-]
> By “difficulty,” I meant that you can set a skill level that's a bit more forgiving
Got it! If anything, it's on beginner level right now and is very forgiving and I need to add maybe two levels above it with pro being at the top. Let me know if you think it needs something even more forgiving than how it works currently and I can try to build that in as a 4th level.
> I had somehow expected a large search bar in the app that I could use aside from the music suggestions to get started.
Yeah, the app relies on you finding the music in the way you normally do in your music players, I'll try and make this clearer. Once you have a few songs in your library however, then you can use that to navigate through them or search them up by difficulty and play them.
> Even though I hadn’t set up Spotify (it wasn’t even displayed), it was still enabled in the settings.
Thanks, will check that out.
> or are the notes transposed an octave when they no longer fit within the scale?
Do you mean this... Now and then a note bar is drawn an octave off its neighbours. The cause is the note model (GAME) choosing the wrong octave for that note. It happens most on pop with heavy backing, where a backing vocal or instrument sits an octave away. I've tried to fix, but the evals get worse so I've not managed to fix that issue yet.
There are definitely some issues I haven't been able to solve yet and it creates terrible pitch tracks for some songs. I have an eval set that I'm optimising through changes so hopefully it gets better over time. It might be at the limits of what's possible with the vocal separation, but I'm hoping that it can get better than it is right now with time and effort.
If you yourself sing an octave above or below, it will draw adjust and score you as on key.
> That's for now, I’ll keep an eye on the project and create issues if my observations become more consistent.

I like the idea, I definitely think there is potential in apps helping with teaching music, of course this isn't anything new, but the direct feedback possibilities have improved a lot with recent ML / AI advancements. As others said, singing is so much more than just hitting the right notes of course, so understanding the scope of the tool is important. But still, it's a neat idea. It's awesome that AI coding tools have made it so much easier to work out these ideas... but also tricky because everyone seems to make their own now, and it's not even per se the best ones that survive.
I've thought about these kinds of apps a lot recently, and am also working on some (not for singing though), I have a programming background (and a PhD in Machine Learning) but still I am impressed by what Claude Code can do so I'm hardly writing a single line of code myself any more. Asking for the right things is still important of course.
dsmurrell 6 hours ago [-]
Yep, this would have taken me maybe a few months (possibly a year) before, learning what I needed to know, and AI brought it down to about 10 days. Also have an ML background but this didn't come into play building this, I got my agent to do the research on what tools were available and which I could use based on their licenses, then created an eval set and tried the tools against one another until I landed on the best set.
For the user's pitch OnKey uses CREPE-tiny (https://github.com/marl/crepe) but ported to Rust with the model running on ONNX Runtime. For the singer's pitch also CREPE but the full version.
This is great, any idea of extending it to musical instruments?

I suspected that extracting played notes out of songs might be more difficult than vocals, but my agent is telling me that it might be possible given its context around the models the app is currently using. I'll experiment with this.

While an approach of associating "notes" with frequencies and singing right with "hitting the frequencies" is what you may naively consider. I think it's more important to get the intervals right, you can take any starting frequency, and as long as you get the intervals right it will sound right, even if the frequency itself isn't perfect. Whereas if you use a frequency based approach like this you will have an absolute frame of reference instead of a relative one
dsmurrell 5 hours ago [-]
Agreed, but if you're singing to the song, then you'd have to match the vocal pitch of the singer otherwise there would be a clash.
Some other singing apps allow you to transpose the entire song but it's easy for them because they play the music. In OnKey's case, it would have to silence the music from the player then replay it shifted up or down. So this might be possible, I'd have to do some experimentation.

Yes, this was me. My confidence has improved through practise to a point where it only half killed me to post that demo video. My family still ask me to relocate when I'm doing this around them... so I think you can hit the pitches and still not sound amazing.
Unfortunately, the way it works, and to avoid any copyright issues, it can't really operate on phones because you can't listen to other apps on them. Maybe the only way is to share your learnt pitch tracks (trained on the laptop) with a mobile companion app.
I wouldn’t take their request to “go somewhere else” as an indictment.
And you can track your scores over the takes you did of a sing in your history. So I think OnKey has you covered on these.
Let me know if it matches what you expect when you try it out.
- By “difficulty,” I meant that you can set a skill level that's a bit more forgiving if you miss the mark, as opposed to a “pro” level, which may be stricter. I’m thinking especially of kids, who might have more fun with it that way. It would also be nice to have a personal profile to choose from, with your own library (?) or at least your own presets (difficulty, progress, etc.).
- It took me a little while to figure out how the app works. You start a song in Apple Music, and the app records it. I had somehow expected a large search bar in the app that I could use aside from the music suggestions to get started.
- Even though I hadn’t set up Spotify (it wasn’t even displayed), it was still enabled in the settings.
- This is probably a bit outside your scope, but in the german song “An Tagen wie diesen, Die Toten Hosen” some (final) syllables get cut off, and sometimes the bars go down even though the melody goes up (or are the notes transposed an octave when they no longer fit within the scale?).
That's for now, I’ll keep an eye on the project and create issues if my observations become more consistent. Thanks for the project!
Got it! If anything, it's on beginner level right now and is very forgiving and I need to add maybe two levels above it with pro being at the top. Let me know if you think it needs something even more forgiving than how it works currently and I can try to build that in as a 4th level.
> I had somehow expected a large search bar in the app that I could use aside from the music suggestions to get started.
Yeah, the app relies on you finding the music in the way you normally do in your music players, I'll try and make this clearer. Once you have a few songs in your library however, then you can use that to navigate through them or search them up by difficulty and play them.

Thanks, will check that out.

Do you mean this... Now and then a note bar is drawn an octave off its neighbours. The cause is the note model (GAME) choosing the wrong octave for that note. It happens most on pop with heavy backing, where a backing vocal or instrument sits an octave away. I've tried to fix, but the evals get worse so I've not managed to fix that issue yet.
There are definitely some issues I haven't been able to solve yet and it creates terrible pitch tracks for some songs. I have an eval set that I'm optimising through changes so hopefully it gets better over time. It might be at the limits of what's possible with the vocal separation, but I'm hoping that it can get better than it is right now with time and effort.
If you yourself sing an octave above or below, it will draw adjust and score you as on key.

Thank you!
One of my methods for my pet projects is just to wait for someone else to do it, worked this time :)
I might chuck this into Claude when I have tokens to spare and see how it'll do with my feature request. Are there any specific apple silicone limitations you can remember? I'll send you a PR if you're interested?

Happy to be of service!
PRs welcome.
I've thought about these kinds of apps a lot recently, and am also working on some (not for singing though), I have a programming background (and a PhD in Machine Learning) but still I am impressed by what Claude Code can do so I'm hardly writing a single line of code myself any more. Asking for the right things is still important of course.

The vocal separation for the song uses UVR: https://github.com/Anjok07/ultimatevocalremovergui

I suspected that extracting played notes out of songs might be more difficult than vocals, but my agent is telling me that it might be possible given its context around the models the app is currently using. I'll experiment with this.
It might only work for single note instruments.
It's got 3 thumbs up but no indication of which OS they're from... maybe I need two issues.
But find it hard to sing to as I don't speak Brazilian Portuguese so it's hard to match the words.
I will ask my friend if it works for him as he speaks the language.
Some other singing apps allow you to transpose the entire song but it's easy for them because they play the music. In OnKey's case, it would have to silence the music from the player then replay it shifted up or down. So this might be possible, I'd have to do some experimentation.
