Loudness is the perceptual quality most closely related to the level or amplitude of an auditory stimulus, which is expressed in decibels. Pitch, the perceptual quality we describe as "high" or "low," can be defined as the property of auditory sensation in terms of which sounds may be ordered on a musical scale (Bendor & Wang, 2005). The idea that pitch is associated with the musical scale is reflected in another definition of pitch, which states that pitch is that aspect of auditory sensation whose variation is associated with musical melodies (Plack, 2014). While often associated with music, pitch is also a property of speech (low-pitched or high-pitched voice) and other natural sounds.  Timbre is closely related to the harmonic structure of a tone. The difference in the harmonics of different instruments is not the only factor that creates the distinctive timbres of musical instruments. Timbre also depends on the time course of a tone's attack (the buildup of sound at the beginning of the tone) and of the tone's decay (the decrease in sound at the end of the tone).
