Ever notice a Guess The Chords session feels like it's reading your mind — right at the edge of "I've got this" and "wait, what was that chord again"? That's not a coincidence, and it's not a fixed level list either.
Every guess teaches the app something
Whether you get a chord right or wrong, how long you took, which chord qualities keep tripping you up, which genres you're strongest in — all of it feeds back into the app. There's no static curriculum where everyone marches through the same 50 exercises in the same order. The difficulty and mix of what you see next continuously recalibrates around you, specifically.

Nine ways to be trained, one engine deciding which
The daily activities aren't one drill repeated — there are nine distinct activity types behind them, each training a different skill: Three Pianos (pick which of 3 pianos just played), Cadence Progression (follow a known chord formula), Which Quality? (classify a chord's quality by ear), Chord Features (yes/no questions about what you're hearing — check the chord encyclopedia for every quality it can ask about), Roman Cadences (name each chord's scale degree — the same roman-numeral system behind our progressions hub), Free Progression (name every chord in an unscripted progression), Same-Type Progression (a progression built entirely from one chord quality), Intervals (name the interval between two notes), and Visual (match notation to sound). The same personalization engine decides, every day, which of those nine you get, in what order, and how hard — so your session and a friend's session on the same day rarely look alike, even if you're both training the same skill level.
From Bronze to Grandmaster: what actually changes
The clearest way to feel the adaptation is the ranked ladder itself — six real tiers, Bronze through Silver, Gold, Platinum, Master and Grandmaster, and the chord vocabulary you're expected to know expands as you climb, not just "more notes."
- Bronze: you start with the basics, deliberately far apart — C major (C–E–G) next to C minor (C–Eb–G). One note different, but the color is night and day, so your ear doesn't have to work hard yet.
- Silver and Gold: sevenths and their closest relatives stack up fast — chords like Cmaj7 versus C6 (three notes shared, one apart at the top), or Dm7 versus Dm7♭5, where flattening a single fifth flips a stable minor seventh into a half-diminished chord with a completely different job. This is where "guess the shape" stops being enough.
- Platinum, Master and Grandmaster: altered dominants and stacked tensions take over — chords like G7♯9 (the "Hendrix chord") next to G7♭9, or full alt-dominant stacks like G7alt against G13♭9. Real cognitive dissonance: two answers that both sound half-right until you've actually trained the distinction.
Want to study any of these before you meet them in a match? Every chord has its own page in the dictionary — notes, intervals, and the real sound. And if it's the progressions themselves you're after, the full cadence encyclopedia has all 79, playable chord by chord.
And it keeps growing
The chord-theory database underneath all of this isn't frozen either — it gets updated as music theory itself develops, so the pool of what the app can pull from to challenge you keeps expanding over time, not just the difficulty curve.
The short version: play daily, and let the app do the work of figuring out what you need next. That's the whole point of building it this way.
