Musical Composition
Defaults: Musical Instrument-2, or to Poetry-2 for song.
This is the ability to compose a piece of music. A successful skill roll means the piece is a pleasant listening experience.
To compose for an ensemble or band without a conductor, you must have a skill level of IQ with at least one instrument in the composition and a skill level of IQ-2 with the rest. Roll at -1 per "instrument group" after the first used in the piece; e.g., a jazz composition for a saxophone section, drums, and bass would require a roll at -2.
To compose for an orchestra or band with a conductor requires Group Performance (Conducting) skill at IQ level. Roll at -1 per general class of instruments after the first used in the piece. Classes include brass, percussion, strings, and woodwinds. Treat choir, harp, organ, or piano as its own class.
This skill includes the ability to read, write, and transcribe music in your culture's notation system (if any). Treat different systems – and different musical traditions – as familiarities (see Familiarity).
