Overtone numbering is offset one step behind harmonic numbering
Evidence
An earlier term still used by many authors for referring to the components of a periodic waveform is “overtones.” The first overtone refers to the first frequency component that is “over” or above f0, which is the second harmonic. The second overtone is the third harmonic and so on. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 790
