So that's what it's called? Myself I've just called it "Roundabout", since I simply try to write a song while running around the same note. No, I have never studied any musical theory in an organised fashion. As a matter of fact, I think about three quarters or thereabouts of my knowledge of musical theory and vocabulary comes from - you guessed it - you guys.
Yea, I've used it quite much of lately - including on your song l'b'xxx, I'll have something soon - and I really like it. You never really have to be afraid of not finding anything at all for a solo or an ending and it still leaves you quite a lot of room for creativity.
