Instrumentation Codes


Humdrum provides standard voice and instrument names in order to facilitate various tasks. Voice and instrument names are used both in tandem interpretations, and in AIN reference records identifying the instrumentation for a work (see Appendix I).

Instrument tandem interpretations are used to identify the instrumentation pertaining to a specified spine. The word "instrument" is used in a broad sense and embraces vocal qualities and vocal types as well as mechanical sound makers.

Three distinctions are currently made in Humdrum: instrument name, instrument class and instrument group. The following table identifies six pre-defined instrument classes:

Code Meaning
*ICvox voice
*ICstr string instrument
*ICww woodwind instrument
*ICbras brass instrument
*ICklav keyboard instrument
*ICidio percussion instrument (idiophone)

The following table identifies five pre-defined instrument groups:

Code Meaning
*IGacmp accompaniment instrument
*IGsolo solo instrument
*IGcont basso-continuo instrument
*IGripn ripieno instrument
*IGconc concertino instrument

The following set of tables list currently defined instrument names. When the name is used to form an instrument tandem interpretation the instrument keyword is preceded by an asterisk, *, and the upper-case letter I. For example, the instrument tandem interpretation for the guitar is *Iguitr. If the guitar appears as an instrument in a AIN Reference Record only the designation guitr is used. The instrument codes in the following tables are available merged into a single list on this spreadsheet.
