This term I took phonetics, and learned about the acoustic analysis applying to speech sound and musical sound, which makes me realize that Chomskian approach isn't indeed the only legitimate method in linguistics, and in musical analysis likewise. Empirical methods can be very productive; but it is on a different level than other methods, for instance, the analysis of the neutral existence of the sound object, namely, the acoustic analysis.Or the cognitive musicology in SEM.Anyway, I'm glad I broadened my vision.
