Did some songwriting/jamming with the band last night. We were trying to work in a bridge on a song and couldn't get the part to feel right. I tossed out the ol' "let's go halftime here" and it seemed to fit pretty well. So the song's cruising along and then, boom, the halftime part hits and it's kinda jarring, but in a good way. I always like that effect and it's fun to play.
We do a similar thing. I like the sudden shock of big, slow, open notes.
