The Greek bouzouki comes in two types: the tetrachordo, with four pairs of strings tuned C F A D, and the trichordo, with three pairs tuned D A D. On this page you will find the fretboard, maqamat, scales and chords for both tunings.
Note: a regular flat (like E♭) is a semitone, so it is blue. Only a half-flat (↓, e.g. E↓ or B↓) is a quarter tone, shown in yellow. Each quarter tone is drawn inside the fret box above it, and if that box also holds a regular note, both are shown side by side. Play it by bending the string or on a fretless guitar.
All maqamat and scales are available on the selected instrument in the fretboard above.
