What do 당신 do during instrumental parts?

i 사랑 instrumentals. I even made an amv on an instrumental! hehe. And i am no 팬 of lyrics matching to the clip, its just the scene and the motion which i love.

When it's at the main part of the Song like the part that has most of it's beat i try to match it up with what ever kinda song it is like say Rock i do faster motions
and when it turns into the sudden quiet parts of the Song i either slow the video down 또는 i leave it as is because sometimes the Video Clip is already slow enough so when the song turns back into the louder part i turn it back to fast X3

That's where I try to emphasize the story I'm telling with clips that don't have mouth movements. The lyrics are good for the general emotions involved, but don't tell the whole picture. Just like the song itself, a video must use both the speaking and the non to get its mood and plot across.
