Recording from 6 September 2004; Premiere by the Doelen String Quartet and New Trombone Collective as part of the Gaudeamus Music Festival 2004.

The idea for slow wave sleep came about from research I was doing about sleep and dreaming for a piece that I wrote in 2003 (lab fly dreams). Slow-wave sleep (also known as stage 3 and 4 non-REM sleep) is characterized by brain wave patterns with a frequency of less than 4 Hz and upper brain inactivity . The mind is ‘out cold’, but the body is free to move around. Sleepwalking, sleep talking and tooth grinding often occur during slow-wave sleep. The piece is based around EEG recordings I made of myself in this state of sleep. I use the sound of the raw data of the electrical activity in the brain and filter it to create rhythmic patterns that are connected with biological rhythms that occur in sleep.

The string quartet and trombone quartet walk in and out of the space as if they are sleepwalking, their sound is processed and distributed in the space. Pulse waves, filtered noise and granular synthesis are the main materials I use in this soundscape.

The idea for the instrumentation came as request from trombonist Koen Kaptijn, to write for the same instrumentation (minus the singer) as Stravinsky’s “In Memoriam for Dylan Thomas” (1954) for the project “Do Not Go Gentle” of the New Trombone Collective. This was then my starting point and reference point during the time I was composing the piece. It seemed to make some kind of sense to write a piece about sleep as an answer to Dylan’s poem “Do Not Go Gentle into that Good Night”.

Slow Wave Sleep (2004)

A live hörspiel by Saskia de Jong and Yannis Kyriakides, produced by WORM / Klangendum together with the Wintertuin in Nijmegen. The inspiration source of geluidhuiden / soundskins is ventriloquism, in the literal and metaphorical sense. In a raw and hypnotic soundscape, inner and outer voices compete to gain dominance, whispering and stuttering.

Deadzone from 'Soundscapes for La Mer'

Excerpt from 12 hour sound installation 'Politicus' for prepared disklavier by Yannis Kyriakides as shown at the Netherlands Pavillion at the Venice Biennale 2011. The work is an encryption of Plato's late dialogue 'Politicus' in which the 'Stranger' and 'young Socrates' discuss the art of statesmanship.

Politicus (excerpt)

trace was written for a dance project of Karin Post's (Take) in 1994. The concept of the piece was based on the early computer drawings of Peter Struyken (who also created the lighting-design for the project), where simple algorithmic rules govern the direction of a line. The basic structure of the four parts of the music is simply a progression of complexity from the ratio 1:2 - 2:3 - 3:4 to 4:5. These proportions are worked out on a rhythmic and structural level.

Premiere performance of Der Komponist performed by the Philarmonie Zuidnederland, conducted by Bas Wiegers at the November Music Festival in 's-Hertogenbosch.
The piece was commissioned to celebrate Helmut Lachenmann’s 80th birthday in 2015.

"Der Komponist, finde ich, hat nicht was zu sagen. Komponist hat etwas zu machen und das was er macht wird viel mehr sagen als was er sagen könnte... sollte auch ihm selbst was sagen...."

“The composer, in my opinion, has nothing to say, the composer must make something, and whatever he makes, will say more than he himself can...it should also say something to him”

(Helmut Lachenmann)

La Mode

La Mode I: Catwalk

Ode to Man was written for 4 female voices (& electronics) from the vocal group Silbersee, for their production Homo Instrumentalis. It is based on the text from the chorus of Antigone by Sophocles (line 332-375) known as The Ode to Man. 

The music is set to the original Greek text, but my personal favourite translation is this one by Anne Carson:

Many terribly quiet customers exist but none more
terribly quiet than Man:
his footsteps pass so perilously soft across the sea
in marble winter,
up the stiff blue waves and every Tuesday
down he grinds the unastonishable earth
with horse and shatter.

Shatters too the cheeks of birds and traps them in his forest headlights,
salty silvers roll into his net, he weaves it just for that,
this terribly quiet customer.
He dooms
animals and mountains technically,
by yoke he makes the bull bend, the horse to its knees.

And utterance and thought as clear as complicated air and
moods that make a city moral, these he taught himself.
The snowy cold he knows to flee
and every human exigency crackles as he plugs it in:
every outlet works but
one.
Death stays dark.

Death he cannot doom.
   Fabrications notwithstanding.
Evil, good, laws, gods,
honest oath taking notwithstanding.
Hilarious in his high city
you see him cantering just as he please,
the lava up to here.

Ode to Man

An improvisation made in my studio in April 2020 on the modular synth. It is largely based on ethnographic cylinder recordings from the Kodaly archive, made in April 1914. These small fragments are sampled with oscillators controlling the grain, loop size and time points of the samples. Pitch and envelope followers on the samples in turn control these oscillators and other physically modelled sounds. Yannis Kyriakides, Amsterdam, April 2020.
