Instrumentation Codes
Introduction
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.
