For every note you play
AudioTheory Piano Keys is interactive software designed to give you audio and visual feedback on what you're playing, as you're playing it. Customise your view using an extensive library of chords and scales that react to every note you play.
Understand scales using an innovative circular diagram where each note is spaced at a relative interval and your root note stays at a fixed position.
View the scale for every note as you play it, relative to your main song key. The perfect tool for improvising, this helps you find the next right note that 'fits' your composition.
