Quizplus · Accepted Answer

The third primary characteristic of a sound wave is timbre, which refers to the quality, tone, or color of the sound. It helps distinguish between two sounds with the same pitch and intensity, such as the difference between a guitar and a piano playing the same note. Loudness is related to the amplitude, while frequency determines the pitch. Melody refers to the arrangement of multiple pitches in a sequence, and noise refers to a random or chaotic sound.
