Three notes with staccato dots

Staccato ([stakˈkaːto]; Italian for 'detached') is a form of musical articulation. In modern notation, it signifies a note of shortened duration, separated from the note that may follow by silence. It has been described by theorists and has appeared in music since at least 1676.
