AudioTheory Guitars

The ultimate reference tool for guitar notes and chords. For anyone who's ever wished music theory was that little bit more straightforward – this is the software for you.

AudioTheory Guitars is the ultimate reference tool for guitar notes and chords. Featuring a built-in keyboard, each note reacts to your input across the customisable chord and fretboard diagrams. For anyone who's ever wished music theory was that little bit more straightforward – this is the software for you.

The full set of features:


  • Seamlessly transcribe between piano and guitar using a straight-forward colour coding system and notation highlighting. Play a note on the keyboard, or directly from the chord and fretboard diagrams to see where it is across all formats.

  • Set your tuning and capo. Everything else adjusts accordingly – no need for a chord transposition chart.



  • Choose your chords with open, power, barre, sus2 and dim7 chord sheets with fullscreen diagrams and playback options.



  • 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 you don't.



  • Scale presets you can quickly apply to the application. Save and load functions to easily swap between customised views.

  • 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. Set your fretboard size, number of strings, start fret and per-string tuning.
