What does transposer mean?
A transposer is a person or device that moves something from one position or order to another. As a person, the word can describe someone who rearranges text, music, or other material, although rearranger is usually more familiar in this sense. Its more distinctive use is in music, where a transposer is an instrument, mechanism, or electronic device that causes music to sound at a pitch different from the pitch at which it was written. This allows performers to hear or play a composition in a different key while leaving the notation unchanged. The word is therefore associated with both structural rearrangement and musical pitch transformation. It is specialized rather than everyday vocabulary, but it precisely identifies the agent or mechanism responsible for such a transformation.

Where does transposer come from?
Transposer belongs to the English word family formed around transpose and the suffix -er, which identifies a person or device performing an action. Transpose comes through French from Latin transponere, a verb built from trans- meaning “across” and ponere meaning “to put.” The same Latin family of putting and positioning underlies words such as position, composition, and deposition.
How transposer is actually used
As a noun referring to a person who rearranges material, transposer is relatively uncommon and literary; rearranger is often more natural. The term is more readily understood in musical and technical contexts for a device or mechanism that shifts pitch or rearranges elements.
