👉 Notes are essentially pure tones produced by a single sound source that resonates at one specific frequency, resulting in distinctive timbres or "colors" of sound when played simultaneously with other notes; these basic sounds form the basis for creating melodies and harmonies in music composition, where different combinations create complex auditory patterns. Sounds, on the other hand, refer to a broader range of acoustic phenomena that involve more than one frequency component, such as chords or rhythms, and often include harmonics, overtones, and other subtle variations that enrich the perceived sound quality when multiple notes are played together.
