Guitar: maqamat, scales, positions and chords

On this page you can learn maqamat and scales on the guitar fretboard (tuning E A D G B E), including quarter tones, and play them position by position at the metronome's tempo. On a guitar with regular frets you get a quarter tone by a slight string bend, and the fretboard marks them in yellow.

RootQuarter tone (half-flat ↓)Other notes (including regular flats and sharps)

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.

Info

On a phone the tuner listens through the built-in microphone. On a computer, choose your sound card or audio interface from the "Input source" list. Automatic audio processing is turned off so the measurement stays accurate. If the metronome plays while you tune, its click may be picked up by the microphone.
