Each tuning starts with a scale fretboard followed by the (7) diatonic chords in the scale displayed in Academic and Intervals. We have grouped each scale and chord together using Academic and Intervals so you can see how the notes relate to each other and where to put your fingers on the fretboard. As you hover over the fretboards, the border colors change based on the tuning.

FretboardGPS has 1,686 tunings for A Ionian. If we filter out the tunings that include notes above standard tuning (to avoid breaking strings), and limit the low notes to (3) whole steps down from standard tuning (to avoid floppy strings), there are 594 tunings to explore!
