In a piano, harmonics are multiples of the fundamental frequency produced by vibrating strings, while resonance frequency is the natural frequency at which an object vibrates most easily. The harmonics of a piano string contribute to the overall sound quality and richness of tone, while the resonance frequency determines the key frequencies at which the piano strings vibrate most effectively.
