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.
