Tripledot

In Western musical notation, a dotted note is a note with a small dot written after it. In modern practice the dot increases the duration of the basic note by half of its original value. If the basic note lasts 2 beats, the corresponding dotted note lasts 3 beats. A dotted note is equivalent to writing the basic note tied to a note of half the value, or with more than one dots, tied to notes of progressively halved value. Any number of dots may be added to a note; n dots serve to lengthen the note by of its original duration.

Although notes with more than three dots do not occur often, one can determine the length of any given note a with n dots: .
