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.
