I am an absolute beginner with basic knowledge on linguistics, phonetics, phonology, poetics or musicology acquired by reading from Wikipedia, and currently attending a short course to learn to use the IPA chart. Despite the practical motivations to pronounce English words correctly, the way sounds, tones and rhythms interacting and resonating with our mind and psychology really fascinates me. I know poetics and musicology may largely be out of linguists' scope, but since phonetics is essential for these fields, I think it is appropriate to ask about its theory and applications here.
Do you know any good introductory book on phonetics, preferably with its applications in poetics or musicology? I have a physics background.
