Purpose:
Anybody remember the old PLAY command in early BASICs, where you could enter a tune encoded in a string and it would play it through the scratchy speaker? This is similar. namedNoteSequenceFrom: expects an array of either:
* Triplets of note (a-g, optionally b or s for flat or sharp, and a number indicating octave), duration, and loudness. The loudness range is 0..1000; 100 is too soft to hear on my PowerMac, and 1000 is full volume.
* Or a double of #rest and a duration.
Sending this to a subclass of AbstractSound will create the sound. Tell the sound to play to hear it.
Why This is Interesting:
Squeak has some powerful music capabilities: sound synthesis, stereo sound, etc. This is a starting point into them. If you look at the class method examples in AbstractSound, you'll find a lot more.
