Turnarounds
for horn and tape
2008
Israel Neuman
The premises of Turnarounds are rooted in the perception of music as transformation of
energy. Potential energy is transformed to kinetic energy with the release of the first
statement and with other following events. The ratio between repetition and change
determines the efficiency of energy utilization. Change creates a forward motion; repetition
creates only the illusion of motion.
Systematic organization of extended techniques, which are manipulated through various
matrix operations, forms the fundamental structure of the piece. Both the horn part and the
tape part are products of this system. The sound source of the tape is derived from audio
recordings of the horn’s extended techniques. In two sections of the piece the performer is
asked to choose a path within an array of musical choices presented to him in a cyclic
notation. These unpredictable repeated cycles are the inspiration for the title of the piece.
Turnarounds incorporates various levels of approximation mainly due to the choice of
material for the horn. While the tape part is fixed, the horn part allows some flexibility in its
performance, as long as important points of alignment are maintained. Those points of
alignment are marked in the score with vertical dashed lines. The tension created by this
approximation is a structural feature of the work.
The tape part is realized in four channels. During performance, an auxiliary monitor is
required for the display of the time code for the performer.
Notation
Performance notes appears inside the score. Below is frequently used notation.
Breath mark – approximately a quarter note
Slashed breath mark - approximately an eight note
Square fermata – hold or rest in duration of indicated seconds
Hand mutes:
Open
Stopped +
½ stopped
Gradual hand change/ hand glissando
with no pitch adjustment
Unusual glissandi
Contour gliss. use half-valve, smooth elongated glissando.
Irregular gliss. random flutter valves.
Written out gliss. use valves, as accurate as possible.
Fast gliss. when indicated, fast ascending glissando.
Tremolos:
regular tremoloalso used withfluttered tonguing
irregular tremoloalso used withrapid irregular tonguing (mix of double, triple and fluttered tonguing)
Trills:
normal trill
microtone trill –trill to the smallest possible interval, either above or below.
