What does definite pitch mean for music?

Definite pitch in music refers to notes that have a specific, identifiable frequency, allowing them to be perceived as distinct tones. Instruments like pianos and violins produce definite pitches, enabling musicians to play melodies and harmonies. In contrast, indefinite pitch refers to sounds that do not have a clear frequency, such as those produced by drums or cymbals. Definite pitch is essential for creating structured musical compositions and scales.
