Fret Sharp

Learn the fretboard

Which fret is which note, and where to find any note on any string — drilled until you don't have to think about it. Fret Sharp measures how fast you answer, not just whether you're right, because that gap is the difference between working a note out and simply knowing it.

Five characters. Enter one you've used before to pick up where you left off, or make one up — if it's free, it's yours.

Letters and numbers, no O/0 or I/1. We remember it in this browser, so you only type it once.

No email, no password, no account. The code is the whole login — which also means anyone who knows it can see that practice history, so don't put anything in here you'd mind sharing. It's a practice tool.

What you'll drill

  • Naming — you're shown a position, you name the note.
  • Finding — you're given a note and a string, you tap the fret.
  • Intervals — unlocked once you can name most of the board.

How it decides what to ask

Weak spots come back sooner, and questions interleave across strings on purpose — practising one string at a time feels better and transfers worse. A position only counts as learned once you can answer it quickly.
