Forum Professional Harpists: one handed bisbigliando

In B. Andres' " Elegie pour la mort d'un berger" is a passage with a bisbigliando in the right hand while the left hand plays the melody. Are there any tips on how to have a nice, clean, fast one handed bisbigliando ( upwards) without cramping ? I never had to play a bisbigliando with only one hand............Is it possible to make it sound as beautiful as a two handed one?
Thanks!

PS; A one handed bisbigliando downwards is somehow easier for me, while a two handed bisbigliando is easier upwards.......... Does anyone have the same or opposite experience?

I personally wouldn't play it, as it sounds like something that practicing would lend itself to injury. But I would think of it as slow, effortless arpeggios, with oscillation and shoulder movement to prevent any possible cramping while learning.

I agree with both Saul and Elizabeth. I first would be very careful of this passge. Sounds like, with any sort of tension, it's a set up for tendonitis. I would experiment with various patterns and notes and possibly considering not making a true bisbigliando, but something that is effective, and not so demanding. Kind of strange to be in one of Andres pieces. He writes so well for the instrument and this sounds clumsy to say the least.

The word Bisbigliando fired a circuit in my brain that had been dormant for years and I wanted to share the memory with you all. The person who played the best (two handed) bisbigliando I have ever heard was Aristid Von Wurlitzer, my undergraduate teacher. His bisbigliando was magic. It had no begining and no end. It was even in tone, rhythm, and volumn like I have never heard anyone else do. You couldn't hear any shift from one hand to the other, and you couldn't hear any pulse to it at all. It was a miraculous bisbigliando. I believe I only ever heard him do a 4 finger bisbigliando, not a 3 fingered one.

I don't know how that came out like that. His name was Wurtzler, not Wurlitzer.

A bisbigliando is a rapidly repeated pattern of notes that is played by both the left and right hand.  It can be a 3 or 4 note pattern, and usually outlines a chord.  Here's an example: Play a 4 note C major arpeggio from the bottom up with the right hand(C,E,G,C-4,3,2,1) then repeat the exact same notes with the left hand.  Repeat this over and over again(right, left, right, left, etc.) with an absolutely even rhytmic distance between the notes, and an absolutely even volumn so that no single note stands out.  It's played very fast so that it sounds like a kind of tremolo.  The trick is to touch the strings at the moment that they are played and not a nanosecond  sooner, and to place in sequence, i.e., place only one finger at a time ahead of the one playing.  With both hands playing right no top of each other you will muffle the sound by placing too early, or placing all four fingers together.  Hasselman's Follets is an entire piece written on a 3 note bisbigliando pattern.
