Question for experimental string players

What is the performance direction meaning: 'To play below the bridge'?

i.e. The sqeaky part.

Thanks,

Rick.

Well, just that? (Usually it's called a variant of "behind the bridge" though.)

There's also a special symbol for it, although like all these extended technique symbols it's not -that- standartised and not known by everyone, so you should still make a verbal annotation, at least in the performance notes. I don't have an image of it on hand right now though and don't feel like drawing it up, but it's basically a set of vertical lines symbolizing the strings (sometimes also reduced to just two) and a small curve across them, symbolizing the bridge.

Great!

Thanks very much.
