Cipher map (Sum Fig. 4.4)

When a tab or msawi formula prints digits 1–8, they mean these string/position pairs — Sum 2012, Chapter 4.2 / Figure 4.4.

Sum Figure 4.4 — cipher ↔ string / position

Sum’s load-bearing map (Ch. 4.2 / Fig. 4.4): digits 1–8 name a string (zir / tahtiya / ntoi) and a finger position (open, 1-A, 1-B, 2-A/B/C). Bracketed [1-B] and parenthetical (2-B)/(2-C) mark pitches Sum treats as extras or scale-variant slots. This is the same map every repertoire tab and msawi transcription on this site cites.

Average intervallic spacing Sum reports under Fig. 4.4 for the common pentatonic succession 1–2–4–5–7–8: 1→2 161¢ · 2→4 335¢ · 4→5 189¢ · 5→7 326¢ · 7→8 202¢. Octave ≈ 1212¢ (not a tempered 1200).
