Well, suppose you hear a melody, and then imagine it for a while 
thereafter; would that not be nonspeech auditory rehearsal?

Tasks such as that certainly seem to involve dorsolateral and 
ventrolateral frontal cortices known to be involved in working memory, 
along with auditory cortex (even in the absence of sound), analogously 
to visual cortex involvement in visual imagery.

(For more on this, see papers by Halpern and myself, available on my web 
site)
