In music, instrumentieren means to arrange a musical work for specific instruments, i.e., to determine which parts are played by which instruments. While Orchestrierung is a common synonym for the broader process of arranging for an ensemble, instrumentieren is used particularly when specifying a given instrumental combination or adapting a score for a particular group of players.

In the sciences and economics, instrumentieren is used in the sense of instrumental variables. This refers to the technique of using external variables as instruments to obtain consistent estimates in models affected by endogeneity. The term appears in econometrics and policy evaluation literature.

In medicine and dentistry, instrumentieren describes the use of instruments to perform a procedure, such as shaping and cleaning tissues or canals. For example, in endodontics the root canal is instrumentiert using specialized dental files.

Related terms include Instrumentierung (instrumentation), Instrumentalisierung (instrumentalization), and, in the musical domain, Orchestrierung (orchestration). The exact meaning of instrumentieren thus depends on the professional field, ranging from physical act of using tools to symbolic acts of arranging or modeling with instruments.
