Thanks for starting to work out a write-up how to deal with sound in Squeak 4.1.

This is interesting. Do you have a reference?

Yes, we need a good way to access sounds. That means 'code idioms'
which are easy to grasp for a beginner to use sounds.
(Or in SW engineering terms - an embedded DSL for handling sounds)
It would help to have a couple of good example statements what can be
done with sound as of now.
Did you check out the Squeak wiki? I found an entry
Squeak sound architecture
I did not go through it.
We need to know what still works or how things are done these days.
This could then be an entry in the 'Help' menu called 'Sound' which
contains code snippets and instructions how to deal with sound.

I agree. And you did that step.

In your service as well
P.S. The class AbstractSound and the subclasses - do they contains
