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:
*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:
*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
