Although ternary most often refers to a system in which the three digits, 0, 1 and 2, are all nonnegative integers, the adjective also lends its name to the balancedternary system, useful for comparison logic.
Ternary is inefficient for human usage, just as binary is. Therefore, nonary (base 9, each digit is two ternarydigits) or base 27 (each digit is three ternarydigits) is often used, similar to how octal and hexadecimal systems are used in place of binary.
Ternary also has a unit similar to a byte, the tryte, which is six ternarydigits.
Ternary form is a way of structuring a piece of music.
As well as marches, ternary form is often found in baroque opera arias (the so-called da capo aria) and in many dance forms, such as the sort of polkas written by the Strauss family.
It is also the form used in the minuet (or scherzo) and trio, which in the classical music era was usually the third movement of symphonies, string quartets, sonatas and similar works.
