Chordial is a complete guide to scales and chord charts for guitar, banjo, mandolin, ukulele and bass guitar.

Use this information to decide where you want to play each chord or scale. The full application also runs on the Apple Watch, with all of the standard instruments, tunings, chords, and scales, but no editing mode.
