Bisbigliando ("whispering" in Italian) is a special tremolo effect on the harp where a chord or note is rapidly repeated at a low volume. Usually, the effect is achieved by both hands playing adjacent strings set to the same pitches. This is possible because of enharmonic spellings created by the pedals. It can sound like strumming a guitar or even "watery". Tremolo is a musical term with two meanings: A rapid repetition of the same note, a rapid variation in the amplitude of a single note, or an alternation between two or more notes. ... The harp is a chordophone whose strings are positioned perpendicular to the soundboard. ... In music and music theory, a chord (from the middle English cord, short for accord) is three or more different notes or pitches sounding simultaneously, or nearly simultaneously, over a period of time. ... In music, pitch is the perception of the frequency of a note. ... The classical guitar typically has 3 nylon and 3 nickel-wound strings. ...
On sheet music, it is represented by three thick lines connecting the notes to be trilled. Sheet music is written representation of music. ...
PS; A one handed bisbigliando downwards is somehow easier for me, while a two handed bisbigliando is easier upwards..........
I just have to add, "one-handed bisbigliando" sounds like one of those strange instruments that P.D.Q. Bach comes up with, like "left-handed sewer flute." And for some reason, composers are always stupidly fascinated with the fact that we have bisbigliando, or as more familiarly known, bisbigl.
A bisbigliando is a rapidly repeated pattern of notes that is played by both the left and right hand.
