Skoove Tools
Music theory you can hear.
Three free tools to help you understand the structure behind every song — chords, scales, and the keys they live in. Built by Skoove.
Piano Chords
Hear any piano chord. See how it's built.
Open tool- Every common chord — major, minor, 7th, sus, dim, aug, add9

Circle of Fifths
The map every songwriter wishes they'd seen sooner.
Coming soon- All 12 major + relative minor keys
- Diatonic chord cards for every key

Scale Visualizer
Every scale, every mode, every key — on a real piano.
Coming soon- 12 scale types including modes, pentatonic, and blues
- Tempo-adjustable practice playback (40–200 BPM)
- Mode rotation — hear the same notes anchor differently
Try it
Every tool uses this same piano.
Tap a key. Use the computer keyboard (A = C, S = D, …). Real Salamander Grand Piano samples — no MIDI, no synth.
Highlighted: a C major chord — root C, plus E and G.
