A Capriccio
Impulsively, as one fancies.
In a musical score, A Capriccio (ah-kah-PREE-choh) is a directive to play a passage in a frivolous and unpredictable manner. This might involve taking liberties with dynamics or tempo, and/or taking a playful, improvisational approach to the melody and the passage as a whole.
A Capriccio is an Expressive card. It gives the okay to be unpredictable, to do the unexpected, to express playfulness; it implies a kind of freedom. It can also indicate a time when unpredictability, frivolity, or caprice is at hand.
