The first four harmonics of a string fixed at both ends. Each rose shape is that mode's up-and-down envelope; the hollow dots are its fixed nodes and the loops between them swing hardest at the antinodes. The highlighted row is the mode your current frequency and speed are driving — raise the frequency and the pattern climbs the ladder.
