Definition
The fundamental frequency is the lowest frequency at which an object or system can vibrate, producing its simplest and most basic sound.
Related terms
Harmonics: These are higher frequencies that are integer multiples of the fundamental frequency. They give a unique character to a sound.
Resonance: This occurs when an object vibrates at its natural or resonant frequency due to external forces matching its own frequency, resulting in increased amplitude and energy transfer.
Overtones: These are additional frequencies present in a complex sound wave that are not harmonics but still contribute to its overall quality.
