  • Seamlessly transcribe between piano and guitar using a straight-forward colour coding system and notation highlighting. Play a note on the keyboard to instantly see where it is in your chords and on your fretboard.
  • Set your capo and everything adjusts accordingly – no need for a chord transposition chart.
  • Exclude notes and never play out of key again. Your fretboard diagram now only shows the notes you need and your keyboard doesn't play the ones don't.
  • Chord and note playback. Select your chords and notes from the diagrams to play them on the keyboard.
  • Midi support. Connect an external Midi input device to control the on-screen keyboard.
  • Full customisation. Select the chords you want. Left-handed mode for left-handed players. Choose between guitar and bass fretboard diagrams.
“The idea behind the software is customisation. It all started when I couldn’t find a diagram of a left-handed fretboard tuned half-a-step-down and had to create my own. Then I tuned back to E and had to update my diagram. Then I wanted to share it with a right handed bass player and... well you get the idea. I realised that I needed to rebuild my diagram in an interactive format. Every feature followed from here.”
–Fraser Mackenzie, creator of AudioTheory Guitars
