Tonal: U+E6D0 - U+E6FF 0.1.alpha1

Proposal 2010-07-

NOTE: This is still a proposed encoding and has not been standardized.

In 1859, John W. Nystrom proposed a hexadecimal (base 16) system of notation, arithmetic, and metrology called the Tonal System. In addition to new weights and measures, his proposal included a new calendar with sixteen months, a new system of coinage, and a hexadecimal clock with sixteen hours in a day.

Digits

The Tonal digits themselves are named, in order and beginning with the English zero, noll, an, de, ti, go, su, by, ra, me, ni, ko, hu, vy, la, po, and fy. Noll (zero) through Me (eight) use the same Arabic glyphs as the decimal system (U+0030 - U+0038). The glyph for Arabic nine (U+0039) is also used for Ko (ten). This script defines new graphs for the digits ni, hu, vy, la, po, and fy.

Units

The Tonal system also defines new units, called meters, galls, tims, pons, horse-powers, dollars, and temps. The abridgement of the units are noted by capital letters (except for temps, which use the digraph Tp), and the multiplication and division of the same as an exponent by a small letter placed before or after the unit, thus, Mt = Meterton, tM = Tonmeter, Gs = Gallsan, Ts = Timsan, Pm = Ponmills, etc. These multiplications and divisions are encoded as combining marks, which can be combined with the standard ASCII letters.

Music

In this system, music is rearranged into five new clefs, called Canto, Alto, Treble, Tenor, and Bass. These new clefs are encoded, and can be used along with the classical musical symbols encoded at U+1D100.

Encoding Structure

The Tonal block is divided into the following ranges:

U+E6D0->U+E0DF Digits
U+E6E0->U+E0EF Unit multiplications and divisions
U+E6F0->U+E0FF Musical clefs
