What does treble mean?
Treble is the conventional English term for the highest register of a voice or the upper part of an instrument. As an adjective, it describes something sounding at a high pitch, as in treble clef, a treble voice, or the upper register of a violin. As a noun, the treble denotes that upper range or the part written for it; musicians may also say that a part is “in treble.” The term is familiar from sheet music, where the treble clef fixes the pitch of the notes written on the stave, but its everyday use extends to descriptions of singing and speech. Treble is not limited to children or women: an adult male singer can sing in a treble register, while a “treble voice” simply means a high-sounding voice. In ordinary prose the word is most often heard in musical or technical contexts. A rare verb, “to treble,” means to sing or play in the treble register. Overall, treble is useful where precision matters, especially when distinguishing an upper register from lower voices such as alto, tenor, and bass.
The highest or upper register of a voice or instrument; the musical part written for that register.
"She sang the treble while the other singers provided the lower harmony."
Common in musical contexts and in the phrase “in treble.”
High-pitched or relating to the upper register of a voice or instrument.

Commonly used attributively in expressions such as “treble voice,” “treble clef,” and “treble range.”
To sing or play in the treble register.
"In this arrangement, she trebles the melody in the upper register."
Rare, literary, or specialized rather than part of everyday usage.
The plural is used when referring to separate upper registers, parts, or voices.

Hidden inside “treble” is “triple”: the name ultimately descends from Latin for threefold, even though modern treble refers to the highest register.

Where does treble come from?
Treble entered Middle English from Anglo-French treble. Its ultimate source is Latin triplum, meaning “triple,” a medieval Latin alteration of a form associated with Latin triplex. The Latin word drew on Greek triplous, meaning “triple” or “threefold,” from the same numerical and folding roots found in modern words such as triple, triplet, and triplicate.
