As a noun, a part is a section of a greater whole. It is normally an intentional segment rather than one caused bydissection. See e.g. Standard Industrial Classification for various categories.
As a verb, to part means to divide or separate.
In the performing arts
Music
A part is the music played by an individual instrument or voice (or group of identical instruments or voices) within a larger work, such as a melody. It also refers to the printed copy of the music for each instrument, as distinct from the score, which holds the music for all instruments. For example in a string ensemble you would have separate parts for Violin 1, Violin 2, Viola and Cello, even though there might be several of each instrument (and therefore several copies of each part).
