ES: valor, I: valore, durata, F: durée, valeur (d'une note), D: Notenwert, NL: nootwaarde, DK nodeværdi, S: notvärde, FI: nuotin aika-arvo.
Note values (durations) are measured as fractions, normally 1/2, of the next higher note value. The longest duration normally used is called brevis, but sometimes (mostly in pre-baroque music) the double length note value longa is used.
An augmentation dot after a note multiplies the duration by one and a half. Another dot adds yet a fourth of the duration.
Alternatively note values may be subdivided by other ratios. Most common is subdivision by 3 (triplets) and 5 (quintuplets). Subdivisions by 2 (tuplets) or 4 (quadruplets) of dotted notes are also frequently used.
