Saba is a maqam with a unique, distinctive sound, sometimes described as sad in character. Its second degree is lowered by a quarter tone and its fourth degree is lowered further (b4), and together they create its special sound.
Choose an instrument and a root above to see Saba on the fretboard.
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.
Degrees: 1 - ½b2 - b3 - b4 - 5 - b6 - b7
Notes on D: D E↓ F F♯ A B♭ C
Notes on C: C D↓ E♭ E G A♭ B♭
In maqam Saba the quarter tones are on degrees 2. On D these notes are E↓. On the fretboard they are marked in yellow, and the symbol ↓ marks a note lowered by a quarter tone (half-flat).
