FretBanshee
Play a note or a power chord. FretBanshee hears the pitch and lights up every position on the neck that produces it — because one pitch is playable in up to six places, and which one you want depends on where your hand already is.
Ready when you are
FretBanshee listens through your microphone and shows every place on the neck that produces what it hears. Audio is analysed entirely in this browser tab — nothing is recorded, and nothing is uploaded.

Scientific pitch notation — E2, F#3, Eb4. Anything that doesn’t parse is reverted.
Single notes are detected with the McLeod (NSDF) method. Power-chord detection is a harmonic-support heuristic scoped to root-and-fifth — it is not a full transcription engine and will not survive a six-string strum. Audio never leaves this tab.
