Fundamental frequency

Fundamental frequency refers to the lowest frequency of a sound or wave, which determines its perceived pitch. In music, it's the note you hear when a string is plucked or a tuning fork is struck. This frequency is crucial because it serves as the foundation for all higher frequencies, known as harmonics, which contribute to the richness and quality of the sound. For example, when you hear a musical note, the fundamental frequency is the primary sound, while the harmonics add texture and depth, creating the unique character of that note.
