Lyra

Lyra is an interactive reference for scales and chords: a guitar fretboard

major/minor and their modes, pentatonics, blues, symmetric scales, thaats
and ragas, plus a custom scale builder.

• Chords: every playable position for the current tuning, with fingering

diagrams.

• Key changes: shared (pivot) chords between two scales.
