Double whole note Double whole note In music, a double whole note (American), breve (international), or double note (; ) is a note lasting two times as long as a whole note (or "semibreve"). It is the second-longest note value still in use in modern music notation (; ). In medieval mensural notation, the "brevis" was one of the shortest note lengths in use —hence its name, which is the Latin etymon of "brief". In "perfect" rhythmic mode, the brevis was a third of a "longa", or in "imperfect" mode, half a "longa" . In modern notation, a breve is commonly represented in
A (musical note) even A-444. Baroque pitch is usually cited as A-415, which is a semitone lower than modern pitch. A0 is the lowest note on the standard piano. The octaves follow A1, A2, etc. A7 is a few pitches lower than C8, the highest note on the standard piano. The note "A" is not considered to be a certain milestone or mark to hit with voice as, for example, Tenor C is, but it can be extremely demanding in certain octaves. A (musical note) La or A is the sixth note of the fixed-do solfège. Its enharmonic equivalents are B ("Heses") which
