ation of the pair of eighth notes.
        The default is 50%, which is no swing; both eights have the same duration and the ratio is 1:1.
        66% is a common value for triplet-swing, with a 2:1 ratio of the first note to the second.
        Other common swing values are 60% which corresponds to a 3:2 ratio of the first note to the second and 57%
        which corresponds to a 4:3 ratio.
        The maximum value of swing is 75; in this case the first half of the pair is 3 times longer than the second
