Regex Editor & Tester

Matches musical chord symbols starting with a root note (A-G), optionally followed by a '5' for power chords, a sharp/flat accidental (#/b), a chord quality (m, M, mM, Mm, aug, dim, add), numeric extensions (6, 7, 9, 11), or suspended tones (sus2/sus4). With global and multiline flags, it's ideal for extracting chords from guitar tabs, lyric sheets with chord annotations, or music notation parsing.
