Pedal direction

[mwf]

Hi,

can anyone tell me what the symbol is concerned with pedalling which looks different to the normal one with the bracket underneath, the symbol I am reffering to is a line with an upwards pointing triangle at regular intervals, I think it means to half pedal or something, because normally you get a direction to say when to put your foot on the sustain pedal and when to remove it, but is the symbol I am going on about mean to half pedal, and if so what do you do? do you only lift your foot off half way up and not to the top? An example of the symbols I am reffering to are used alot in nyman's score for the piano film, 'the heart asks pleasure first'.

Thanks.

This is the modern notation (as opposed to "Ped." and "*")

The initial vertical line means "depress pedal". The triangle means "repedal" (quickly release pedal and press it again); the last vertical line means release pedal. To my knowledge, there is no sign for "half-pedaling".
