Theory on the Neck

Learn intervals, keys, and harmony on the fretboard.

Accord makes theory easier to see by mapping scale degrees, chord tones, interval relationships, and diatonic harmony directly onto the neck.

Intervals become visible

Instead of memorizing interval formulas away from the instrument, players can see how each interval appears on the fretboard.

Understand chord function by degree

Accord helps players study tonic, predominant, and dominant behavior by relating each chord to its scale-degree role inside a key.

Connect theory to practice

Music theory becomes more useful when it is attached to the same shapes, notes, and fretboard positions you use while playing.

Useful for lessons and self-study

Players working through music education, private lessons, songwriting, or improvisation can use Accord as a visual theory reference and training tool.
