FRETBOARD × KEYS

How to use this tool

💡 THE IDEA

Guitar and piano share the same 12 notes — but they look completely different on each instrument. This tool trains you to instantly connect the two: see a note on one, find it on the other.

🎸 Fretboard
🎹 Piano

Over time, you build a mental bridge between fretboard positions and piano keys — useful for songwriting, ear training, music theory, and communication with other musicians.

🎮 HOW IT WORKS

1
Press to start. A note lights up on one instrument with a sound.
2
Find and click the same note on the other instrument.
3
Correct? Green flash + connecting arc. Next challenge auto-starts.
4
Wrong 3×? The answer is revealed in orange, then you move on.

🔀 THREE MODES

Cycle through modes with the 🔀 button in the top-right corner:

🎸→🎹 Guitar → Piano — a note appears on the fretboard, you find it on the piano keys.
🎹→🎸 Piano → Guitar — a key highlights on the piano, you find it on the fretboard.
🔀 Mixed — alternates direction every 3 challenges. Best for all-round practice.

🎯 DIFFICULTY CONTROLS

Below the fretboard, use the String and Fret filters to narrow down what the game asks you:

🎸 String filter — click individual strings (e, B, G, D, A, E) to practice only those. Click All to reset. Multi-select: click several strings to combine them.
🔢 Fret range — choose 0–5 (beginner), 0–9 (intermediate), or 0–12 (full first octave). The game only picks positions within your chosen range.

Recommended progression:

Start: 1–2 strings, frets 0–5
Build up: all strings, frets 0–9
Master: all strings, frets 0–12

🎹 MIDI KEYBOARD

Got a USB/MIDI keyboard? Just plug it in — the tool auto-detects it. Play a note on your physical keyboard instead of clicking. Works for both piano and guitar answers (note-matching).
