The phrase signifies a flexible approach to musical time, literally meaning “robbed time” in Italian. This implies a subtle pushing and pulling of the tempo, where some beats are lengthened at the expense of others. An example would be slightly accelerating through a passage of excitement, only to compensate by slowing down in a subsequent, more reflective section, maintaining an overall balance of timing.
This technique allows performers to express greater emotion and nuance, lending a sense of spontaneity and personal interpretation to a piece. Its historical significance lies in its emergence during the Romantic era, a period that emphasized individualism and emotional expression in music. Composers often relied on this element to convey deeper meaning and connect with the audience on a more profound level.
