Guitar Fretboard Explorer
Map any scale or chord onto the neck. Pick a tuning and a root, then read the notes, the intervals or the scale degrees off the fretboard — and click any fret to hear it.
A Major (Ionian) — scale positions
The root note is filled in solid. Click any dot to hear that note.
Formula
Click a note in the formula to hear it. Degrees are labelled with the interval above the root; for extended chords a 9th is the same pitch class as a 2nd, and an 11th as a 4th.
About this tool
The explorer works out the pitch class of every position on the neck from the tuning and the fret number, then keeps the ones that belong to the scale or chord you have chosen. It can show those positions as note names, as intervals measured from the root, or as scale degrees — the three ways players actually think about the neck. The root is always filled in solid, so the shape of the scale stays obvious even when you change keys. Every position is clickable and sounds through a filtered oscillator pair written for this tool, and open-string labels on the left turn indigo when the open string is itself the root.
