scelsi/uitti resonators


scelsi/uitti resonators june 2009

Interview from a meeting at Udin&Jazz, June 28 2008 published in the Rivista della Fondazione Isabella Scelsi in Italian.
The rivista drawing is of one of Giacinto's originals, the middle photo is of the later models I redesigned, while the bottom photo is of the model I made for Giacinto shown flipped back when not in use. (The 'butterfly' body normally sits between the strings on the normal bowed side, the wings vibrating on top of the strings)

Luciano: Tell me about the sordinos you redesigned with Giacinto in the 70's.

FM: Thank you Luciano, First I'd like to say that technically speaking, they aren't mutes at all as mutes are used to dampen the sound- but they are actually resonators designed to produce a low rumble. When I asked Giacinto why he wanted to incorporate this sound into the second quartet and Triphon, he said that this sonority reflected certain Tibetan ritualistic practices wherein a ground tone, or vibrating sound was produced to evoke a certain magical power along with the Tibetan flutes trumpets and chanting monks.
As a practitioner myself, I haven't been able to verify these practices in the Buddhist canon; perhaps it was a visionary interpretation derived from his own meditative experiences.

Luciano: When did this all take place?

FM: I met Giacinto in the mid-seventies and almost immediately began to work on his solo cello composition Triphon (1956). We soon discovered that the metallic resonator he'd developed with a New York sculptor had some basic design problems for performing musicians. When playing forte or fortissimo it vibrated so heavily on the bridge that it lost its stability; it vibrated itself loose and eventually fell off. Of course this was an impossible situation for performance.

Luciano: Why did Giacinto ask you, a performer, to redesign his resonators?

FM: A bit of personal history will help you understand why I got involved in all this: the seventies was an exciting period of experimentation in timbric research. I was very much involved in all this as well as improvising solo and in groups such as Nuove Forme Sonore. This lead me to develop a chordal technique wherein the cello could be played polyphonically, first with an extreme convex bow that I commissioned from Roman luthier Giorgio Corsini, and later through the use of two bows in the right hand. By having one bow under the other over the strings, one could play 2,3,4 strings simultaneously and any combination of non adjacent strings that my previous work with a curved bow couldn't obtain. And relevant to this interview, it was during these years that I developed several preparations on the strings and resonators for my own music including one that amplified difference tones in quasi-unison playing, producing an octave below the sounding pitches. Giacinto was aware of my work of course and asked me if I could improve the design for his own mute. I agreed to try. I'd seen several variants of his original resonator produced in copper and brass in differing proportions with weights soldiered on the top. They were all hand made and exuded the charm of antique relics that one might discover in the back room of a monastery. The body of some were made in brass while the weight was copper and vice versa, which led me to think that the designer, while keeping the basic form, was experimenting with the differing sonoral properties. They were all constructed of a thin double metal sheeting which straddled the strings loosely while balancing on top of the bridge, with another double strip that straddled the back of the bridge as a grip . It would be normal for a skulptor to assume these were secure on the instrument as the legs and tail extended a considerable length below the strings from the bridge. But for a player it was soon obvious that with extreme vibrations of the strings in forte playing, they slowly worked themselves higher and higher on the bridge until they eventually tipped over and fell off. (see my sketch in Rivista pdf)

Luciano: We documented some of this in the Rivista Isabella Scelsi

Luciano: How did you solve this problem?

FM: To redesign them, two fundamental requirements needed to be addressed: uninhibited vibration on the strings and at the same time, complete stability. I decided to experiment using the same materials as the originals. During this experimentation period, one problem presented itself: in Triphon the sound of the resonator needed to be reduced or eliminated in the second movement and reintroduced in the third. Therefore the design needed to accommodate these back and forth changes quickly, without time consuming or clumsy actions of putting on and off in performance.

I experimented with modifications that straddled the strings like Giacinto's resonator, but without much improvement. Only by departing completely from the original resonator did I find new model that worked; a floating "butterfly" design whose wings rested loosely on top of the strings while the body was weighted between the strings.

This allows the performer to flip it backward without removing the fastenings. Later on, I made several variants of this design, weighting it down with lead.

Luciano: You used them for the recordings that you made with Giacinto, no?

FM: Giacinto liked the sound and design so much that he took me to his own lawyer who set up an appointment with a patent attorney. The attorney told us that it would be very expensive to take out a worldwide patent, pointing out that without a large commercial market, a patent wouldn't be worth it. But the lawyer added that we automatically had the copyright on them with my signature, so it wasn't pursued further.
Giacinto asked me to make up several extra sets for quartets as well as some reserves.

I used this model when I premiered the Trilogia in the Como Festival in 1979 and again for the recordings we made of the Trilogia both in the International Studio in Rome, and again when I recorded the Trilogia and Ko-Tha in a better acoustical space with Dutch radio producer Frans von Rossum. Giacinto agreed that these latter tapes were far superior and they were eventually used for the Raretone vinyl release and later again for the Etcetera cd release with Michel Arcizet. After changing ownership several times, it is now available through in the Netherlands.

Luciano: Are these older recordings available?

FM: While preserving the original archive of all Giacinto's tapes by transferring from reels to DAT. I did run across some recordings of Devy Erlih and others, but never found those old recordings we did in the International Studios. In any case, the published recording is the one that Giacinto and I both preferred so perhaps the first one isn't of importance.

I subsequently redesigned the resonator with brass weights instead of lead (see above), the design principle and sound being the same and recently made up a set of these for the Flux String Quartet's Scelsi series at Miller Theater, New York.

Scelsi/Uitti Resonators update

It has recently come to my attention that a Swiss "modification" of my resonator originally requested and created for G Scelsi, is in reality an almost exact copy of my work. The shape is practically identical to the original, the materials used are the same and the basic design features of the butterfly-winged free suspension between two strings with a swing mounting is copied.

Upon testing and comparing the copy to the original, we found that the former didn't resonate consistently on the up and down bow, with the up bow producing almost double the volume. The original produces an equal resonance at all dynamics, bow speeds, and bow placements.
Upon further examination it was confirmed that the size of the copy was almost 1/3 larger and heavier than the original, and that there were other features that might have caused volume discrepancies. Perhaps lateral rocking caused by the ring mounting on the tail is a factor.
(see comparison photo above)

The original resonators are the result of many months spent in experimentation and prototyping. Giacinto and I finally agreed to use this model for its appearance, sound quality, and volume. He subsequently handed it out to his interpreters for use in concert.
For further historical information on the original resonator, please see interview in the
Isabella Scelsi Foundation Magazine.

-just scroll down to the middle of the page-

The copies, produced in Switzerland without my knowledge or permission, are based on my original resonator which G. Scelsi gave to another musician to use in a performance.

To avoid confusion, recent and ongoing production of the original Scelsi/Uitti resonators are signed on the underside of the tail. Each is tested on the instrument for consistent sound and functionality.

I would be pleased to work with the above person or any expert craftsman to reproduce the authentic version of this resonator, provided it sounds the way Scelsi wished and is credited properly.
