Those are both interesting articles - but they brought to my mind the fact that speech itself has been used as/ seen as music for at least 40+ years.
I am thinking in particular of the "phase music" of minimalist composer Steve Reich's 1966 piece "Come Out" - in which phase differences begin to make spoken word into sound until it is unintelligible.
I composed a piece using snippets of radio preachers, who after endless repetition in the context of other speakers and musical phrases found their pieces sounding no longer like words but like music, and also the composition of a former professor of mine wherein he literally transcribed the pitches of conversations and used them as the basis for a contemporary art music piece.
Personally, I can sit and listen to 72 tracks through a console in a studio control room - and hear just the kick drum, or just the bass part, etc. even as they are being played back as a mix - and switch attention at a moment's notice. This seems similar - the skill of being able to pull one thing out of a huge audio stew.
I was asked at a noisy party not long ago "Did you hear what he said?" - Yeah - a good 80% of it. My NT interlocutor understood less. And yet Audio Processing Disorder seeems linked to Autism.
It's an area that deserves further study - but I'd like to see the science people include the hardcore music and audio people into the designs of the studies.
There's stuff we hear daily quite differently from what regular people do - and that kind of learning and practice might well be of use to autistic kids.
But the original book that I cited touched on the themes of repetition and orderliness in music as a way of connecting Neurotypicals, who enjoy the same things about music, with how autistic people approach everyday life.
Great articles, though.
This is a link to a very recent re-mix by Ken Ishii of "come Out" - I suggest the original, but it seems unavailable on YouTube.
