Show HN: Cadence – A Guitar Theory App

https://cadenceguitar.com/
89•apizon•1w ago
Hello HN, I just released this music theory and ear training mobile app for guitar which I've been working on for a bit more than a year on the side.

The idea was to make something for the eternally "intermediate" guitarist (myself included). There are a lot of beginner apps which rely on learning songs, toolkits which give you a bunch of stuff with no explanation but not many in-between apps to actually learn and practice more generic and somewhat advanced stuff.

The app contains short lessons, recaps and most importantly challenges (visual, audio and pure theory) along with a very complete library.

The challenges are made for practicing, they will get increasingly harder and getting to the max score is supposed to be quite hard. The idea being that you have to repeat them regularly until your brain has integrated the info and it flows naturally rather than being a one time quick dopamine shot. This is partly inspired by how language learning apps work.

It has no ads, a lifetime purchase option and you can use it without an account if you don't care about multi-device sync or backing up your progress.

(This is my second and last post about this sorry for spam. My first post a few weeks ago didn't get any views and posting on a saturday might not have helped...)

Very nice! What's under the hood?

Ui looks nice mate! I’d consider myself an eternally intermediate guitar player. Hit a level of competence and haven’t had the time/drive to move past it. Slightly unrelated, but I’ve always found the current ear training apps to not really translate to helping me pick out songs by ear.

I’ve always wanted an app that focuses more on learning songs by ear, finding the root not and chords/melodies, vs just isolated interval recognition. I’d love to improve at this while on the train which an app would be great for.

I’ve tried: Functional Ear, Earpeggio, and Perfect Ear. Functional ear is my favorite but I find it isn’t translating into my jam sessions.

My experience with ear training is that you really need to connect it to your instrument. If you're on the train where you can't play, obviously it can't hurt to train interval recognition and chord quality - but the ultimate point of training your ear is to build that connection between what you hear in your mind and what comes out of your fingers on the instrument.

If there's one "secret trick" exercise for guitar (and other instruments, I assume), it's singing as you play. Put on a loop and try to just sing the notes as you play them. Or scat a little lick and then try to replicate it on the guitar. It's really effective, it feels like it just "gets to the heart of the issue."

It works to boost interval training too - grab a root note somewhere, play, say, a minor third, get that sound into your head, and then sing it as you play it.

Transcription is also really helpful. Print out some blank tab, download Transcribe! so you can slow / loop sections, pick a song you like, grab your instrument, and just start trying to figure it out. It's grueling at first but it gets a lot easier with practice. As a side benefit, you get to steal licks from players you like.

For the most part, the great players are people who did a ton of this - whether it was rock guys listening to the same blues record over and over and learning the licks, or jazz guys doing obsessive transcriptions. Steve Vai famously found his way into Frank Zappa's band because he sent copies of his transcriptions to Zappa himself.

I’m trying this on my iPad.

My first bit of feedback is that the icons in the right column should be higher contrast. For me, they are difficult to see.

Also, I see the icons are eye, mortar board, and ear. What’s the fourth icon?

I’m solidly in the beginner camp (even though I’ve been trying to learn guitar for 35 years now), so maybe this isn’t for me. I’m going to kick the tires this weekend.

The name is misleading. Initially i thought it was about creating new guitar designs. First time i heard "Guitar Theory", maybe OP was thinking about Music Theory, which, in itself, is a vast subject. It is more a harmony app, a.k.a. a Guitar Chord App. Other than that, it is a nice app to learn how to play individual chords.

These are fun to make. But the real value prop would be demonstrating the effect of following the proposed practice the app indicates.

…have you yourself actually tried it? Where was your technique and where is it now?

Thank you so much for sharing this! My kids all play instruments and I'm a bit jealous of their skill (I never played anything growing up). Over the last few weeks I've taken to borrowing my son's guitar at night and working through one of his books. I've been looking for more information on music theory, and this is so perfect. I'm excited to go through it. Thanks again!

Pretty good! Translation by AI? First lessons quite well, but first quiz in German "Welche dieser Noten ist... ganze Tonoberhalb?" makes no sense.
