undulations
Rolling wave patterns
Undulations are wavelike motions or forms—the gentle rises and falls of a surface or movement.
The word captures both the shape and the rhythm: the undulations of rolling hills, the undulations of a snake's body, the undulations of the music.
Anything that flows in smooth, repeated curves undulates.
