music-glossary: alla breve
1.10 alla breve
===============
ES: alla breve, I: alla breve, F: alla breve, à la brève, D: Allabreve,
alla breve NL: ?, DK: ?, S: ?, FI: ?.
[Italian: âon the breveâ] Twice as fast as the notation indicates.
Also called in cut time. The name derives from mensural notation,
where the tactus (or beat) is counted on the semibreve (the modern whole
note). Counting âon the breveâ shifts the tactus to the next longest
note value, which (in modern usage) effectively halves all note values.
In mensural notation, breves and semibreves can have a ternary
relationship, in which case alla breve means thrice (not twice) as fast.
In practice, this complication may not have mattered, since Gaffuriusâs
system of multiplex proportions makes it easy to explicitly state which
proportion is needed.
