Harmonic The nodes of a vibrating string are harmonics. Two different notations of natural harmonics on the cello. First as sounded (more common), then as fingered (easier to sightread). A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency, i.e. if the fundamental frequency is f, the harmonics have frequencies 2f, 3f, 4f, . . . etc. The harmonics have the property that they are all periodic at the fundamental frequency, therefore the sum of harmonics is also periodic at that frequency. Characteristics[edit] Harmonics and overtones[edit] An overtone is any frequency higher than the fundamental.
