Organology is not, as you might expect, the
study of organs--either human or pipe--but rather, the
study and classification of musical instruments in general, which just doesn't make any goddamned sense. Why isn't it called "instrumentology?" It is a field that musicologist usually enter when they can't even hack their own field, so that in the hierarchy of
music it is sort of
like second viola in a string quartet.
Organologusts, only a step above Musical Iconographers (
q.v.), have to resort to the study of the forms, history, and classification of the instruments that real musicians get to play and that real scholars get to write about.
