A Persian — Chicago Tuning Banjo

A Persian is 7 notes to the octave (world family), drawn here across the Chicago Tuning Banjo's DGBE strings with every A marked, so home stays visible from anywhere in the pattern.

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.

Because these four strings are the guitar's top four, patterns a guitarist already owns land here unchanged. The work is rhythmic rather than geographical: making the pick articulate every note the head refuses to sustain.

Run it against a click at a tempo where every note gets the same weight. On a banjo an uneven scale is audible immediately — the instrument gives you no sustain to hide behind.
