# 36-EDO Alterations

The following table shows the alterations in the 36-tone equal-temperament system (36-EDO, sixth-tone system) up to the seven sixth-tone.

- go — Gould notation
5 × 2 combined arrow symbols after Gould (U+E270 - U+E279), and Standard sharp / flat symbols (U+E260 - U+E264).

- arrow — Arrow notation
Half arrow symbols (hook) after Ezra Sims (U+E2A4, U+E2A1), and Standard sharp / flat symbols (U+E260 - U+E264).

All symbols are placed either alone or a standard symbol is combined with one of the other symbols.

- sag — Sagittal notation
6 × 2 Spartan Sagittal single-shaft and multi-shaft symbols (U+E304 … U+E335) after George D. Secor and David C. Keenan.

This is the "Pure Sagittal notation" in contrast to msag. It uses one distinct symbol for each degree up to the whole tone. For higher degree, two symbols are combined.

- msag — Mixed Sagittal notation
1 × 2 Spartan Sagittal single-shaft symbols (U+E304, U+E305), Standard sharp / flat symbols (U+E260 - U+E262, U+E264) and large double-sharp symbol (U+E47D). They are placed like arrow.

- wys — Wyschnegradsky notation
5 × 2 symbols after Iwan Wyschnegradsky (U+E421 … U+E434), and Standard double-sharp / flat symbols (U+E263, U+E264).

The notation uses one distinct symbol for each degree up to the whole tone. For the remaining degrees, two symbols are combined.

- bos — Bosanquet commatic notation
Two comma symbols (sloping lines) after Robert H. M. Bosanquet (U+E479, U+E47A), and Standard sharp / flat symbols (U+E260 - U+E264). They are placed like arrow.

- haba — Hába notation
5 + 3 symbols after Alois Hába (U+F661 … U+F670), and Standard double-sharp / flat symbols (U+E263, U+E264).

The notation uses one distinct symbol for each degree ascending up to the whole tone and descending up to the semitone. For the remaining degrees, two symbols are combined.

Hába's symbols are defined as “Optional glyphs” in the Ekmelos font since they are not included in SMuFL.
