What does instrumental mean?
Instrumental has two broad, well-established uses. In general contexts, it describes someone or something that helps make a result possible: a negotiator may be instrumental in reaching an agreement, or careful planning may be instrumental in a project’s success. The word often suggests an important or enabling contribution, so it is more emphatic than merely saying that someone helped. In music, instrumental refers to music performed by instruments rather than singing. It can describe an entire piece of music, an instrumental version of a song, or a musical passage without vocals. The related noun refers to such a composition or passage. The word comes from the Latin instrumentum, meaning “instrument” or “means,” and its modern figurative sense developed from the idea of being an instrument in bringing about an outcome.
Serving as a means or important factor in bringing about a result.
"The mayor was instrumental in securing funding for the new library."
Commonly used with “in” followed by a gerund.
Relating to music played by instruments rather than sung.
"The band released an instrumental version of the theme song."
In music, it may describe a composition, arrangement, or passage.
A musical composition or passage performed by instruments, typically without vocals.
"The soundtrack combines several dramatic instrumentals with dialogue."
This noun is less common than the adjective and is especially associated with film, television, and game music.
Plural is used for separate instrumental compositions or passages.
"The film features several suspenseful instrumentals."
The word “instrumental” can describe both a crucial helper and music made without singing: one person is instrumental in solving a problem, while a band can release an instrumental recording.

Etymology of instrumental
Instrumental derives from Latin instrumentalis, meaning “pertaining to an instrument or means.” The underlying noun instrumentum referred to a tool, device, or means of accomplishing something. English adopted instrumental in the late 16th century for both the general sense of serving as a means and the musical sense of music performed by instruments. Its figurative use for a person or factor that makes an outcome possible reflects the older idea of an instrument used to achieve a result.

How instrumental is actually used
When describing a contribution, “instrumental” is usually followed by “in” and a gerund: “instrumental in improving the service.” In music, it commonly means a version of a song without vocals, although it can also refer more broadly to music composed for instruments. The adjective is often formal or descriptive rather than neutral everyday vocabulary.
