Vivace
Vivace is Italian for "lively" and "vivid". It is pronounced [viˈvaːtʃe] in the International Phonetic Alphabet.
Vivace is used as an Italian musical term indicating a movement that is in a lively mood (and so usually in a fast tempo).
The speed typically coincides with that of "Molto Allegro" and implies a metronome marking of 132-160 beats per minute.
