Aauuttooppooiieessiis

Aauuttooppooiieessiis è un brano dello sperimentatore austriaco Arno Steinacher pubblicato per la netlabel LuvSound.

Nei suoi lavori Steinacher cerca di tradurre modelli e idee scientifiche in musica. In questo caso l’idea alla base del brano è l’autopoiesi, termine coniato nel 1972 da Humberto Maturana a partire dalla parola greca auto, ovvero se stesso, e poiesis, ovverosia creazione. In pratica un sistema autopoietico è un sistema che ridefinisce continuamente sé stesso ed al proprio interno si sostiene e si riproduce. Un sistema autopoietico può quindi essere rappresentato come una rete di processi di creazione, trasformazione e distruzione di componenti che, interagendo fra loro, sostengono e rigenerano in continuazione lo stesso sistema [wikipedia].

Ne esce una musica piuttosto affascinante, minimale nella sua essenza, ma in continua trasformazione, dando l’idea di evoluzione automatica e spontanea.

Note dell’autore:

The basic idea of this work was to explore the term autopoiesis, which means selfcreation. In the context of theoretical life science, autopoiesis is often said to be the most fundamental principle of living systems.

To a certain extent autopoietic processes consist of repeated cycles of self-recurrance: glycolysis for instance, photosynthesis or autocatalytic RNA reactions. These processes are organized modular, forming a regulation network. As self-recurrance never happens exactly, there is space for errors and individuality, which in many systems causes something new on another level. This is one of life’s attributes: to create new dimensions spontaneously, another may be unrepeatablility.

“Aauuttooppooiieessiiss” reflects on and plays with these ideas. It consists of several loops with two main origins: instruments and machines, which stand for organic versus anorganic matter. The instrumental parts were all produced with electric guitar, the machine parts were for some part recorded in a factory near Vienna in 1999. Some loops run in parallel in many copies, but each copy differs in tempo and starting point. No situation in this work is repeated, every rhythm that emerges is ephemeric and takes place just one time, although it may be very similar to its neighboured ones, before and after. This ephemeric patterns that just arise at some times in this piece were my focus during the composition process.

One of the surprising results for me was that self-recurrence of machine sounds caused a more organic situation than the guitar-loops, which merely seemed to transform their sonic quality.

.at/on

.at/on is musician and composer Anton Holota from Ukraine.

.at/on main soundwork is offered through electroacoustic ambient and glitch and drone flavors. ‘fon a’ and ‘fon b’ are two small pieces of glitch ambient and experimental noise that together make up one complete story. ‘scape-01’ and ‘Products of Passed Days’ are much more on the ambient drone side, lenghtier and more spatious pieces, with a twist of dark ambient throughout.

Album excerpts:

Clepsydra

Clepsydra è un brano di Radulescu per 16 sound icon.

Questo strumento è una invenzione dello stesso Radulescu. Si tratta di un pianoforte privato del coperchio e appoggiato su di un lato, in verticale, in modo che sia possibile accedere alle corde che vengono suonate in vari modi: pizzicate, percosse oppure passando fra loro dei fili di nylon o dei crini, con risultati simili ad un archetto. L’accordatura è non standard, definita dall’autore. In fondo è simile al bowed piano di cui abbiamo già parlato.

Inner Time II

Inner Time II, op.42 (1993), di Horaţiu Rădulescu, è per sette clarinetti in SIb.

La struttura delle altezze è basata su una scala non temperata di 42 note ricavate dalle parziali 6, 7, 8, 9, 10, 11 e tutte le parziali dispari fino alla 83 di un LA basso (enfatizzare le parziali dispari, in effetti, è coerente con il timbro del clarinetto).
La nota derivata dalla 6a parziale è la più bassa e corrisponde al MI basso del clarinetto in SIb; la più alta, quella della 83ma parziale è appena sotto il RE più alto nell’estensione di un clarinetto in MIb.
In questo brano, però, tutti i suoni sono ottenuti da clarinetti in SIb.
Le 42 note della scala sono suddivise fra i 7 clarinettisti: ognuno di loro deve imparare a eseguire 6 note. Dico imparare perché, derivando direttamente dagli armonici, la scala non è temperata, ma naturale ed è richiesta una notevole precisione di intonazione essendo le altezze definite a livello del 64mo di tono. Dorante le prove vengono usati degli accordatori elettronici per aiutare gli esecutori a trovare la giusta intonazione.

Inner Time II è un omaggio ad Alexander Calder (quello dei mobiles). Qui Radulescu applica la tecnica del filtro di registro, il che significa che seleziona solo alcune parti della scala proprio come se vi applicasse un filtro passa-banda. In effetti l’intero brano è uno spostamento graduale dalle alte verso le basse frequenze con tempi diversi, come i vari elementi di un mobile che ruotano gli uni attorno agli altri.
La struttura temporale, comunque, è molto complessa e fa appello anche alla sezione aurea e alla sua controparte, la serie di Fibonacci.
Se volete maggiori dettagli, potete leggere le note di programma (pdf in 3 lingue).

Decisamente un bel brano, affascinante anche se non facile perché Radulescu non conosce compromessi, basti pensare che il tutto dura quasi un’ora e lo svolgimento è molto lento.

Il lavoro degli esecutori, poi, è superbo, anche se, quando sento brani di questo tipo giocati tutti sulla precisione dell’intonazione che va oltre il sistema temperato, mi chiedo se non sarebbe il caso di utilizzare l’elettronica, senza sottoporre gli esecutori a inutili crudeltà.

Soft Morning, City!

Un altro brano di Tod Machover dopo Light. Anche questo è distribuito da AGP da cui potete scaricarlo in formato FLAC.

Si tratta di Soft Morning, City! che presentiamo con le note dell’autore, è per soprano, contrabbasso e suoni elettronici sia sintetici che ottenuti elaborando gli strumenti. Il testo è tratto dal monologo di Anna Livia Plurabelle, nel Finnegan’s Wake di James Joyce.

Soft Morning, City! (which was commissioned by the Calouste Gulbenkian Foundation for Jane Manning and Barry Guy) presents its qualities more immediately and directly. This is due mostly to the presence of James Joyce’s text, the final monologue from Finnegans Wake. The particular passage that I have chosen here has interested me for many years. Coming at the end of this monumental epic, it is a melancholy and moving swansong of the book’s main female character, Anna Livia Plurabelle. Now appearing as a washerwoman, she recalls her life as she walks along Dublin’s River Liffey at daybreak. Many different planes of narrative are interlaced, the mundane with the spiritual, the sexual with the aesthetic, the personal with the universal. Joyce achieves the closest thing to the temporal parallelism of music by snipping each layer of narrative into short, constantly varying and overlapping phrases. The great beauty is that Joyce creates not the eclectic choppiness that such a procedure might suggest, but a majestic form of tremendous power and sweep. It seems to me that Joyce achieves this through an organization of the over-all sound of the passage in an unprecedented way. Listening to a reading-aloud of the text, one is carried by its cadences, tidal flows, crescendos and dvina-awavs, even while being sometimes onlv half-sure . , of the meaning of certain words. it is the rare combination of polyphonic verbal richness with inherent sonic structure that makes it ideal for a musical setting.

My setting takes the form of an aria, though a rather extended and elaborate one. Attention is always focused on the soprano, who alternates between long melodic lines and short interjections that change character quickly. The double bass lends support to the soprano, provides harmonic definition and melodic counterpoint, and often adds musical commentary.

The computer tape helps to amplify, mirror and extend the myriad reflections of Anna Livia, but at the same time acts as a unifying force. To emphasize closeness to the live performers, a new process is added whereby soprano and double bass music is directly transformed by the computer, producing at times sounds that seem to fuse the two into one musical image.

The work begins in stillness, with the soprano evoking the atmosphere of morning, surrounded by an ethereal transformation of her own breath. With the entrance of the double bass, various different strands of the textual polyphony are introduced one after the other, each with characteristic music. As the sonority of the tape gets closer to that of the live instruments, the musical layers begin to overlap with greater rapidity. In the lengthy middle section, many different layers are superimposed so that at the moment of greatest intensity and complexity a new unity is formed.

From this plateau, the rest of the work is built. Quiet communion is achieved between soprano and bass. This leads directly to a long melodic section, with soprano accompanied by a continuous harmonic progression in bass and tape.

After a final moment of lonely reflection (“O bitter ending!…”), an enormous wave washes over Anna Livia and carries her away. A quiet coda uses delicate, distant images to recall the stillness of the work’s opening. A chapter is closed, a deep breath taken, and we prepare, led by Joyce’s Liffey (“Riverrun…”), to begin again.

Light

AGP ha ripubblicato recentemente alcune incisioni di musica elettronica degli anni ’80 che trovate nell’Internet Archive ai numeri 106, 107, 108 da dove potete scaricarle in FLAC.

Il 107 contiene due brani di Tod Machover, compositore americano del 1953 molto attivo anche in area multimediale.

Qui vi faccio ascoltare Light, un pezzo del 1979 scritto per l’Ensemble Intercontemporain più due flussi elettronici preregistrati ottenuti mediante elaborazione di suoni strumentali.

L’autore spiega in dettaglio il brano:

The piece takes its title from a quote by Rider Haggard, the English fantasy author: “Occasionally one sees the Light, one touches the pierced feet, one thinks that the peace which passes understanding is gained – then all is gone again.” The atmosphere and expressive content of the work reflect these words, which also influenced the choice and treatment of musical materials.

From a single melody (heard in entirety only at the climax of the piece) a complex polyphony is developed that creates layers of simultaneously overlapping, shifting musical planes, like independent clouds that move each at its own speed, and part momentarily to allow rays of light to pass through. Each of these layers is characterized by a different musical elaboration of the same basic materials. The largest contrast is between the instrumental ensemble (14 players) and two separate computer-generated 4track tapes. Each of these tapes represents a different (and opposing) approach to the elaboration of musical structures. The first uses traditional instrumental timbres and playing techniques as a starting point and transcends the “normal” by extending past the human capacities. The second explores microscopic details of sounds derived from these same instruments, although the connection between the two worlds is made clear only gradually during the course of the piece.

The instrumental ensemble is musically situated between these two approaches. It is divided into four sub groups (string quartet; woodwind quartet; piano, harp and wood/skin percussion; trumpet, trombone and metal percussion), each of which develops a distinct set of musical tendencies, and possesses a clear timbral identity. The piece was conceived for IRCAM’s experimental concert hall, or Espace de Projection, where all acoustical and physical characteristics are controllable. The instrumental ensembles are placed in the four comers of the room, on platforms, with the public seated in the middle. Tape I is distributed through 4 speakers, one placed over each instrumental group, thus emphasizing the “instrumental” departure point for this tape’s electronic sound. Tape II emanates from a set of 4 speakers placed on the ceiling of the hall, to exaggerate the separateness of this ethereal and delicate murmuring that develops gradually into the thunderous crashes that mark the climax of the piece.

The piece begins by emphasizing the distinctness of all its various layers. Each group follows its own developmental principles in a section that culminates in a series of cadenzas. After each group has had its say, all material is combined in the large solo of Tape I which builds until the first crashes of Tape II. In the quiet that follows, a new, more homogeneous order is built up gradually, and leads to a final section of delicate chamber music, where equality prevails among all the diverse elements. The main harmony of the piece provides the basis for a meditative coda, which dissolves into the isolation and bareness of the final piano notes, a shadow of the defiance and brilliance shown by the same instrument at other points of the piece.

The musical form is dramatic, the expressive mood quite romantic, and both are founded on a conviction of mine: that faced with todafs confusing kaleidoscope of equally valid parallel lifestyles, cultures and ideas, the only response is to search quietly but resolutely for a deeper truth, perhaps out of nostalgia for a lost simplicity, but hopefully from a courage aid belief in a “new order” of synthesis and unity behind the surface choas. It is this search that I have tried to portray in Light.

a pressure triggering dreams

“a pressure triggering dreams” (1996-1997) è un brano del compositore americano David Felder (b.1953), per orchestra ed elettroacustica dal vivo nella forma di campioni di flauto elaborati elettronicamente e affidati a un campionatore per l’esecuzione. Completano la parte elettrica un basso elettrico e una amplificazione selettiva di alcuni strumenti.

Concettualmente ho qualche riserva (i.e. perché proprio suoni di flauto?), ma il risultato sonoro non è male, frenetico e ad alta energia, anche se gli interventi elettronici si sentono solo in particolari punti e a volte si fatica a discernerli nella massa orchestrale.

Ma forse questo è proprio quello che il compositore voleva. Comunque ognuno può farsi la propria opinione. Ecco le note di programma e il brano

“The work a pressure triggering dreams was commissioned by the American Composers Orchestra for Carnegie Hall, for a premiere in May 1997 … [It] was to be a work that included electronics. I elected to respond to this request by incorporating a companion ‘orchestra’ consisting entirely of computer-processed flute sounds within the orchestral tapestry and to expand the orchestra by using live sampler keyboard, electric bass, and by selectively amplifying solo instruments. […]

“The title is a rough translation of some remarks made by Friedrich Nietzsche in The Birth of Tragedy (1870-1871) when he is speaking of the effect of Richard Wagner’s musical language upon the listener — this remark characterized my subjective response to the piece I was then composing and therefore serves as a kind of emblem for the composition. A wide variety of materials (extracted from my series of ‘Crossfire’ pieces — soloists, electronics, video, and computer processing of acoustic materials made by the individual musicians) is deliberately compressed in the attempt to create an atmosphere of saturation somehow related to the experience of persistent musical afterimages suggested by Nietzsche’s brilliant observations.
