Gulf–Bandari 4/4 Method

Abstract

Two layers, one groove

Many musicians describe the Bandari feel as 6/8, 12/8 or a “Khaleeji” swing. Arrangers, guitarists, educators and producers who work in a 4/4 environment need a stable way to write and program it without losing the regional groove.

The method separates two layers. The practical layer is a performer-readable 3+3+2 grouping on a 1/32 grid, used for teaching, rehearsal and guitar mapping. The analytical layer places the three attacks of each beat at 0 / 13 / 23 / 32 on a 1/128 bar-grid, used for DAW and MIDI work.

The difference between the two layers (12 + 12 + 8 versus 13 + 10 + 9 units) is a consistent micro-timing offset of +1 / −2 / +1 per beat, about 19–20 ms per unit at 93–98 BPM.

In practice

Guitar, ensemble and DAW

• 0 — low anchor: bass string or low muted stroke; kick or low drum (dohol).
• 13 — inner response: upstroke or high-string stroke; ghost snare, clap or rim (keser).
• 23 — closure and pickup into the next beat: high-string stroke or mute; shaker or hand percussion (pipeh).

Accents, fills and ornaments are kept on a separate layer, so the base three-attack cell stays clear. For teaching, students start with the 3+3+2 layer and meet the 0 / 13 / 23 / 32 model only as an advanced timing reference.

Scope and status

What the method is — and is not

The timing values come from the author’s repeated listening, transient-onset inspection and DAW comparison of Bandari groove segments from the Bandar Abbas / Hormozgan performance context. Live playing clusters around the model (13–14, 23–24) rather than landing on it exactly.

This is an independent, fieldwork-informed technical note. It has not been peer-reviewed. It does not claim that Bandari rhythm was invented or first documented by the author; traditional Bandari, Gulf and Southern Iranian rhythmic heritage remains collective cultural heritage.
