= monitor loudspeakers

Sound Equipment

Each synthesizer player has a monitor loudspeaker beside him, which should be powerful enough to enable abalance of all instruments in rehearsals and for performances in small halls. The monitor loudspeakers of these players should, if possible, sound equally loud when playing or . In addition, for performances in larger halls, all instruments must be amplified: the winds with 6 microphones, the percussion in struments with 3 microphones, and the synthesizers with leads to the mixing console in the hall. (For the world première, S1 and S3 each had two leads, and S2, S4, and S5 each had one lead.)

All signals are circuited to a mixing console at the middle of the hall, where each has an individual fader and panorama potentiometer. There, they are mixed to stereo, dynamically balanced and projected over 2 x 2 loud speakers which are at the left and right above the stage, circa 4.5 m high.

Notation

Time

1 – 42	=	numbered moments. The moments follow each other with out a break at a sign given by the conductor.
–	=	6 groups of instruments.
	=	duration of 12 seconds.
START	=	Conductor starts a stop-watch (in his left hand).
STOP	=	Conductor stops the stop-watch.
1'23"	=	1 minute and 23 seconds from START until here.
ca. 37"	=	Conductor gives entry at about 37 seconds into the total duration of 83 seconds.
	=	7 beats of the conductor; the intervals of entry of the beats are free (if a tempo is not notated, as is the case between 19B and 20). He stops or starts groups with such beats.
	=	quite long.
	=	Conductor gives "soft" beat for a non synchronous stopping and starting of in struments (for example the transition from 5 to 6 etc.).
rit.	=	slow down to about half-tempo.
accel.	=	speed up from slow to fast.
IRR	=	irregular.
MORSE CODE	=	irregular rhythm, like Morse code.
REG	=	regular (periodic).
IND	=	individually (each player independently).
SYNCH	=	each entry is conducted.
STACC	=	relatively short sounds.
	=	tenuto (do not shorten duration).
LEG	=	legato.
LONG	=	long sounds or noises.
CONT	=	sustained sound or sounds (with out interruptions, but not slurred).
	=	repetition of the same pitch.
	=	tremolo with 2 pitches.
	=	gradual transition.
	=	conductor gives entry.
		The traditional indications and are used in a more general sense: there are irregular and regular (periodic) pitch repetitions and tremoli, i.e. slow ones, ones which accelerate, fast ones, and ones which slow down.
	=	flutter- tongue (Flzg.)
	=	pitch is sustained.
	=	glissando.
	=	caesura.

Pitches

All pitches sound as written.

Included with the performance material is a part with transpositions for bass clarinet, basset-horn and soprano saxophone.

In the parts for these instruments, the synthesizer notes of groups , , and are also transposed in the moments which are transposed.
If the soprano saxophone player can play other sections having lower pitches with a lower saxophone (for example, baritone), he (she) transposes these pitches him / her self.

Depending on the range of his instrument, each interpreter chooses pitches from those indicated, and changes them in any order, if not instructed otherwise. At the instruction change pitches with conductor SYNCH, the pitches may only be changed with each beat of the conductor.

Sounds – Noises

New, characteristic sounds should be produced by each synthesizer, which are also not imitations of any familiar sounds. The timbres should change as much as possible during the 42 sections.

Trumpet and trombone may use various mutes. At several places wawa mute and straight mute are prescribed for the trumpet, and wawa mute is prescribed for the trombone.

NOISES = All kinds of noises which can be produced by synthesizer or
                 sampler and instrument; they should be different in each noise
                 section, taking into account the prescribed dynamic level.

= noise sections.

The individual parts of the 5 synthesizers, as in the recording of the world première in 2002 ( CD 64 ) may be ordered from the publisher on 5 individual compact discs.

Dynamics

If several signs are indicated for dynamic levels, such as / / / / , then the player may begin at any level and freely permutate all of them.
