Sound is created by vibrations that travel as longitudinal waves through solids, liquids, or gases. When these waves reach our ears, the brain interprets them as sound. Sound has five basic properties: pitch, which depends on frequency, with higher frequencies producing higher pitches; loudness, determined by amplitude, where larger amplitudes result in louder sounds; timbre, the unique quality of a sound, formed by its specific combination of harmonics and overtones, which is why a piano and a violin sound different even when playing the same note; duration, or how long a sound lasts; and velocity, the speed at which sound travels through a medium. Designing musical instruments relies heavily on the relationships between the physical properties of sound (frequency, amplitude, waveform, etc.) and human perception (pitch, loudness, timbre, consonance, dissonance) to create, organise, and express music…read more on NOPR
