*****************************************************************
In Western musical notation, a dotted note is a note with a small dot written after it. The dot adds a half as much again to the basic note's duration. 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.
