Try experimenting with the HelpBrowser.
Ah, sorry if what I wrote seemed to imply I will do something - I will not.
On sound and music in general, I have for years provided an image with a lot of contents and documentation (including help browers, and also notebooks that are way more dynamic):

Before I do anything else in this area, I would expect feedback on that work - and so far I never had any, which lead me to conclude that there is in fact no interest in this topic (of course I'll be happy to be wrong, but again I will only be convinced after someone has actually reviewed even a fraction of what I have done).
