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

The auditory image of a melody can be "recoded" in a verbal or spatial 
format. Thus, subjects required to rehearse a melody may not really 
rehearse a purely auditory (sensory) image.
There is evidence that a purely auditory image cannot be rehearsed 
efficiently, at least during a silent delay. See:
