Yes, inspired. But no, that's not what started it. I haven't actually found how to simulate those type of sounds in GarageBand without a MIDI keyboard. There's probably a way. And I can always can always fall back to FruityLoops/LMMS for that.
What I have now is more of a symphonic mess. Strings, piano, a bit of (simulated) clean guitar, and some flutery. It's just what came out. Who knows what I'll get next time!
