"the tune itself then is, because it relies on the intermediary's transcription." I agree, but suggest, with respect, that to fit with the definition we have been working with fully, some comment could be made upon the approach to transcription of the transcriber. Eg for Sharp we know something about the way he tried, when faced with singers who often sang successive verses differently, to produce something representing the essence. For me, just assigning the label 'mediation' is less interesting and useful than making use of the concept to interrogate what is offered to the end user of mediated material and, ultimately, to support evaluation of that material.
