In fact, many of the current shortcomings of contemporary pronunciation teaching relate quite directly to its not being sufficiently artistic (tied to expressiveness), musical (attending to prosodic features such as intonation and rhythm) and "physical" (cf. HICP, of course!) Likewise, when the education culture sees art, music and physical education as first in line during budget cutting, it should come as little surprise that pronunciation instruction falls in the same category. Although there are any number of reasons within the recent development of the field from communicative language teaching forward for the declining interest in pronunciation teaching, the trend represents a more general evolving, post-modern societal attitude toward form, body and person.
Pronunciation teaching as we know it, as a more or less discrete, "skill-based" specialization that is of sufficient value to the field such that it should be reestablished in teacher training programs in these times of fiscal and form-based restraint may well be beyond resuscitation.
