drum kit

This term refers specifically to the integrated assembly of percussion instruments, distinguishing the entire setup from a single drum. While "drum set" is a common synonym, "drum kit" is more frequently used in British English and professional musical contexts to describe the physical hardware and instruments as a unified tool.

Because it describes a composite object, it is treated as a standard countable noun. It is typically modified by adjectives describing the size or type, such as "acoustic drum kit" or "electronic drum kit," to specify the technology used.
