Toolbox
Every demo from the lessons, as a tool you can come back to. Each one remembers its settings in the address bar, so you can bookmark or share exactly what you see.
- Keyboard & staffPlay notes and see them written on the staff. Hold two notes for the interval, three or more for the chord name.
- Metronome & rhythm tapperKeep a steady beat at any tempo, or tap along to rhythms and see how close you are.
- Scale & mode explorerPick any root and scale to see and hear it. Compare two side by side — only the notes that change will move.
- Interval trainerExplore every interval with sound and sight, or train your ear with the intervals you choose.
- Circle of fifthsEvery key, arranged so neighbours share all but one note. Tap a key to turn the circle, see its signature, and hear its chords.
- Chord builderStack thirds, name the chord, and invert it. See it on the staff, keyboard, and fretboard.
- Chord quality trainerHear a chord and name its quality: major, minor, diminished, augmented, or a seventh chord.
- Progression ear trainerRecognise common progressions and cadences by ear.
- Progression sandboxDrag Roman numerals into a timeline in any key, play it back with a rhythm, and watch the harmony and voice leading.
- FretboardScales and chords on guitar, bass, or ukulele — with chord shapes and fingerings.
