Chords Scales Tuner Fretboard Theory Intervals

Chords, scales, tuning, and theory in one clear view of the neck.

Accord helps you study chord shapes, map scales across the neck, train intervals, understand keys, and stay in tune without bouncing between separate tools.

Accord brings the core pieces of practice into one system.

Chords, scales, fretboard memory, intervals, harmony, and tuning all reinforce each other. Accord is built to make those connections visible instead of splitting them into isolated utilities.
