Treble refers to tones whose frequency or range is at the higher end of human hearing. In music this corresponds to "high notes". The treble clef is often used to notate such notes. Examples of treble sounds are guitar tones, piccolos, etc.Treble means the highest part in a composition that has three parts which came from the Latin “triplus.” It is characterized by a very high pitched sound or tone and is the higher part in a recording. They have frequencies from 2.048 kHz-16.384 kHz (C7-C10). Treble sound is the counterpart to bass sound.
The term "treble" derives from the Latin triplum, used in 13th century motets to indicate the third and highest range.
The treble control is used in sound reproduction to change the volume of treble notes relative to those of the middle and bass frequency ranges.
