C# Persian — Double Bass

The C# Persian scale runs 7 notes per octave in the world family. Below it sits on the Double Bass's EADG strings with every root marked, because a bassist reads a scale map as a set of targets around the root, not a row of dots.

Intensely exotic — two half-step clusters (b2 against the root, b5 against the 4) and a raised 7th make it the most dramatic of the world scales. Mysterious, ornate, and tense.

Heard in: Persian and Middle-Eastern-flavored melodies, film scoring for desert and ancient settings, and exotic metal and progressive-rock riffs.

The Double Bass has no frets to trust: the map marks positions on the fingerboard, and the audio is there to keep your intonation honest — match each note by ear, pizzicato first, then with the bow.

Walk it slowly against the audio, land each root on a downbeat, then take it to the progressions in C# and let the scale turn into lines.
