Interactive Music Theory Cheat Sheet

One bit of complexity that lots of tools like this seem to always punt on is the fact that most chords (at least in jazz) are typically played rootless and inverted and with lots of 'upper extensions'. It would be nice if a tool really did a deep dive in actual chord voicings that one would play in the real world (i.e. in a context where the bass player is covering the root and therefore it is best left out of the chord).As an example of something that is very systematic (easy to put in an app), a rootless C maj 7 is equivalent to an E min 7. A rootless C min 7 is equivalent to an Eb maj 7. etc.It is a pretty tough leap to learn rootless jazz piano comping when almost everything out there (except for the old-school dead tree books) only ever shows rooted voicings.

This is fantastic. I didn't grow up learning music and found so much of it seeming arbitrary and incomprehensible. This really pairs well with a 30min video[0] I watched taking away so much mystery and showing 'patterns in the madness'.It would be good if there were some keybindings to play notes (e.g. digits for I, II, or letters for notes ignoring #/b, or "r t y u i o p ["). A toggle to label the notes that are part of the selected key could help a beginner like myself.[0] <a href="https://www.youtube.com/watch?v=rgaTLrZGlk0">https://www.youtube.com/watch?v=rgaTLrZGlk0</a>

This is like my own little tonality calculator, except with good UI/UX, and with two changes (Ionian/Aeolian) instead of arbitrary changes. What would be super cool would be to combine the best of both somehow. My change calculator is at <a href="https://edrihan.neocities.org/changedex" rel="nofollow">https://edrihan.neocities.org/changedex</a> if anyone wants to derive harmony of changes which are not Ionian/Aeolian. Though it looks like a turd from 1997, and the audio doesn't work, it does expand this idea to include all 12-tone possibilities, which I call changes. Also hit me up if you like OP!

I made a site the other day to help me practice my chords - <a href="https://learnyourchords.com" rel="nofollow">https://learnyourchords.com</a>If you have a MIDI keyboard you can play along as it prompts you with chords, or if not you can use it like chord flashcards.

That is great! It would have been even cooler if it had some common chord progressions or resolutions for each scale. I'd also add the harmonic and double harmonic, melodic, phrygian dominant (flamenco/hijaz) and Neapolitan scales. Why not also break down the scales in to tetrachords and make it possible to navigate between scale-tetrachord?

Amazing. I only wonder why the post didn't link to the homepage instead. I would not forgive OP if I have missed all the other tools:<a href="https://muted.io" rel="nofollow">https://muted.io</a>

What would nice is a circle of fifths that could be used as keyboard to play sounds. Everything else seems to respond to clicks.

Looks neat (and like you've put a lot of time and effort into it!), but why use the letter 'b' instead of a flat symbol in the section Diminished Chord Formulas (<a href="https://muted.io/chord-formulas-intervals/#diminished-chords" rel="nofollow">https://muted.io/chord-formulas-intervals/#diminished-chords</a>)? I played around with the <a href="https://muted.io/mini-music-machine/" rel="nofollow">https://muted.io/mini-music-machine/</a> a bit, again, very cool - there's some curious use of terminology (esp. interval to mean essentially mean duration/frequency, and the various options under that same dropdown aren't immediately obvious in meaning). Would be awesome if you could save/export whatever you'd created! Is the record button supposed to work? It doesn't for me in latest Chrome on Windows, get this in console:<pre><code> tone.14.8.42.min.js:1 Uncaught DOMException: Failed to execute 'connect' on 'AudioNode': cannot connect to an AudioNode belonging to a different audio context. at De (https://muted.io/js/tone.14.8.42.min.js:1:14949) at uu.connect (https://muted.io/js/tone.14.8.42.min.js:1:29482) at Sd (https://muted.io/js/tone.14.8.42.min.js:17:36141) at I.connect (https://muted.io/js/tone.14.8.42.min.js:17:35056) at https://muted.io/mini-music-machine/:2403:12 at Array.forEach (<anonymous>) at recordStart (https://muted.io/mini-music-machine/:2402:11)</code></pre>

This is nice. I think it has appeared before on HN. A nitpick is that the piano keys are drawn incorrectly; on a real piano the black keys are not centered between the white keys (most important), and they are also wider and longer.

Any good introductory guide for learning the very basics of music theory? I have no real practical need for it but have always been really curious about it. This cheatsheet is very cool but a lot of the terminology is beyond me.

One app I use frequently when composing is Tonaly on iOS. It has an interactive circle of fifths that also indicates the chord grades on the selected scale. The cheat sheet is also a good approximation.

I just started learning the piano again, and using modern apps (such as Simply Piano) makes it actually fun. Ten years ago, I couldn't bear through reading sheet music, making mistakes and got discouraged. But now, learning to play is like playing Guitar Hero. You get instant feedback, guidance on what and how to play. It's great. We'll see how long it stays "fun", but atm I'm making progress every day.

I've seen similar references before but this is very well done, so I've bookmarked it. Particularly like the overlapping keyboard

This and the other one you posted with the chords (I assume that was also you?) are really useful and handy! Thanks for this!

Neat. A version for guitar might be quite popular. Also extending the range of scales. Pick your favorite ones from the 4096 possibilities or maybe all of them :-) [0][0] <a href="https://ianring.com/musictheory/scales/" rel="nofollow">https://ianring.com/musictheory/scales/</a>

Very interesting, would be nice to have a switch to change the notation (at least the solfeggio/solfege one). I'm European and really I can't work with C D E F G A B.

I need a harmonization cheat sheet. Hmmm - I should check out ChatGPT and see if it's able to harmonize. Piano and guitar would be great.

Neat! I like it.I get no audio on my iphone though for the interactive keyboard. Might just be my setup.
