Note: A erformance of To ragments on Water and Light requires the use of additional custom technology in the form of hand-built controllers. urther, a erformance of this iece requires the use of a Max/MS atch. If you are interested in erforming this iece, additional resources and information are required. lease contact the comoser directly (troyal7563@aol.com or tmroyal@uncg.edu) in order to receive the Max/MS atch and the instructions on building and connecting the controllers.
Levis Exsurgit Zehirus for voice and invisible instruments By Thomas Royal
Levis Exsurgit Zehirus for voice and invisible instruments Levis exsurgit zehirus Et sol rocedit teidus, Iam terra sinus aerit, Dulcore suo difluit. Lightly rises the est ind And the sun roceeds teidly, No the earth bares its breast, Seet in its floing aart. rom Cambridge Songs, No. 40 (Loose literal translation by the comoser) Levis Exsurgit Zehyrus is a iece for solo voice and to erformers using controllers built by the comoser. One erformer lays the Torion lus and, hile the other lays the Lichtflöte and controllers the automated electronics using a foot edal. Toriton lus: This controller, designed by Sebastian Tomczak at the Electronic Music nit, Elder Conservatorium of Music, niversity of Adelaide, consists of bol or late of ater hose surface is disturbed to roduce sound. This might be done by bloing or touching. Generally, this controller is used to control a hysical model of ind chimes. 1 The controller might also be used to rocess other sounds, or to lay back the voice in an altered ay. : The Bls are made u of four ooden bols ith contact microhones attached to each of them. The sounds of the bol being struck or scraed are icked u by contact microhones and fed into a banded aveguide model of a bell. 2 The tuning of the bell is determined in advance, though it changes throughout the iece. The art is notated on a five line staff. Each of the saces corresonds to one of the bols. If bols of different sizes are used, the largest should be number 1, and the smallest should be number 4. It is notated thus: 1 2 3 4 Note that this does not indicate hat sounds are made, but hat motions are used to create the sound. Lichtflöte: The Lichtflöte is a tube that lights u at one end. It also has three keys at the oosite end. A light source is laced at the other end of the tube. This instrument is used to control a hysical model of a flute. 3 The ider the mouth is oened, the louder or more intense the sound of the hysical model. itch is controlled using the keys at the oosite end and the other hand, hich covers u the other end of the tube. The choice of itch is imlemented like a brass instrument. Electronics: The erformer ho lays the Lichtflöte is also resonsible for ressing the edal at indicated oints. The staff for the electronic art indicates the aroximate tuning of the hysical models, hether or not a sound is being samled, various actions taken by the comuter, and the routing of sounds into the delay line of various hysical models. 1 Cook, erry.

Nubibus Atris Nubibus atris condita nullum fundere ossunt sidera lumen. Si mare volvens turbidus Auster Boethius The notation and erformance methods of Nubibus Atris are very similar to Levis Exsurgit Zehirus. There are a fe imortant differences. : There is no indication of itch given in the score. There are moments hen the vocalist is called on to hiser, sing, do both, or even transfer beteen one method of vocal roduction to the other. lease follo all erformance instructions as given by the score. Toriton lus / : The are often sent to delays ith feedback in this iece, not an organized aveguide. The music should be layed in the same ay as the revious movement. Lichtflöte: or the most art, itch is not indicated for the Lichtflöte. Rather, lines are given to indicate the level a articular hole of the light flute is to be oened or closed. The holes should remain closed throughout the iece unless otherise indicated. At certain moments, the letters C and O aear. The letter C indicates a hole that is comletely closed. The letter O indicates a hole that is comletely oen. At some laces, traditional note heads are given. roduce the sound as done in the first movement, by oening the mouth to lay a sound, and closing it to end the sound. inally, a trill line ith a symbol of six circles searated by a slash is a trill indication. Alternate beteen the to fingerings given by the notation.
