Question

Quizplus · Accepted Answer

In this case, the first note was played softly, which means the amplitude was low, while the second note was played with a lot of force, resulting in a higher amplitude and therefore a louder sound wave. Timbre refers to the unique qualities of a sound produced by a particular instrument or voice. Frequency and wavelength are related to pitch, not loudness.
