Tiny Instrument

Nine chapters take you from the very first key press through scales, intervals, chords, and harmony — each lesson building on the last. You always know where you are and what comes next, so there's no guessing what to study.

Every concept is taught through action — you play the notes, hear the intervals, build the chords, and feel the ideas before they become abstract. Lessons are interactive exercises, not text to read through and remember.

Narration walks you through each step out loud. Guided retry means a wrong note prompts a nudge, not a dead end. Note labels, search, and visible completion progress are all on by default so nothing feels hidden or overwhelming.

Alongside the structured chapters, Play & Explore opens up scales, modes, chord shapes, and technique in a less rigid, more sandbox-style layer. You can wander into it whenever the theory needs a more musical, hands-on context.

Notes, Intervals, Scales, Chords, and Melodies are each their own ear training track with their own progression. You can focus on the area you're weakest in or work through them in order — either way you always know exactly where you stand.

Listen covers exactly the same vocabulary as Learn — the same intervals, the same scale names, the same chord types. That means what you hear in ear training maps directly onto what you study in lessons, and the two reinforce each other instead of drifting apart.

A round takes a minute or two, so returning to ear training doesn't feel like a commitment. The flow is quick, the feedback is immediate, and the round ends before it gets tedious — making it easy to come back every day.

Scale Practice, Chord Practice, MIDI Practice, Song Library, and Warm-ups each target a distinct area of technique. You can zero in on the thing that needs work without wading through everything else — every mode has its own flow and its own kind of challenge.

Each session tracks your score, average, and personal best so repetition accumulates into visible progress. Session history shows you how a drill has gone over time, which turns a dry exercise into something that actually rewards coming back.

Before you begin, you choose the key, octave range, tempo, difficulty level, and what to focus on. That means a scale practice session can feel like a beginner warm-up or a serious technical exercise depending entirely on how you set it up.

Short mini-games appear inside practice sessions to break the rhythm and keep things lively. They're quick enough to feel like a break and musical enough to still count as practice — note identification, sharp-or-flat challenges, and more.

The keyboard stays visible and central at all times, so every idea you explore is immediately tied to touch and sound. Nothing is buried behind menus — you tap a key and hear it, and the whole interface responds around that moment.

Optional notation context and note labels keep abstract theory anchored to something visible. You can see the note on the staff, the name on the key, and hear it at the same time — which builds a much stronger connection than learning from a diagram alone.

A built-in instrument library lets you switch between piano, organ, synth, and more without leaving the playing surface. You can hear how the same scale or chord feels on different timbres, which makes instrument curiosity part of the learning.

The chord and scale explorers let you browse every voicing and every mode shape directly on the keyboard. Tap a chord quality or a scale name and the keys light up — so exploration stays musical instead of turning into a flashcard exercise.

Tap any chord in your progression to swap it, change the voicing, or try a different quality — the surrounding chords stay in place and the whole flow stays inside Compose. You can hear the progression loop as you edit so every change lands in musical context.

Change the key of your entire chord progression in a single tap. Every chord updates instantly, so you can audition different keys until you find one that fits your voice, your instrument, or the feel you're going for — without rewriting anything manually.

Compose is designed to feel approachable before it feels powerful. There are no tracks to set up, no routing to configure, and no learning curve just to put four chords together. It's the right level of complexity for someone making their first musical sketch.

A chord progression you build in Compose can be sent to Practice for drilling or opened in Play for improvisation. What you learn in theory and ear training can land here as real musical material instead of staying abstract — Compose is where the rest of the app pays off.
