The wave is an ornamental tone that fluctuates rapidly between the main tone upward or downward and the neighboring tone (usually a second).

Waves can be categorized as single or compound according to the number of fluctuations, and as up or down according to the upward or downward fluctuations, with the downward fluctuations being indicated by the addition of a vertical line in the middle of the wave notation.

Waves can also be accompanied by a temporary change sign, which indicates that the neighboring note is a change note.
