Bisbligliando

Bisbligliando is a special trill?ing effect on the harp where a chord or note is played quickly over and over again. Usually, it is with both hands playing different strings but the same pitch?es. This is possible because of enharmonic spellings created by the pedals. It can sound like strumming a guitar or even "watery".

On sheet music, it is represented by three thick lines connecting the notes to be trilled.
