Acustica

Composto fra il 1968 e il 1970, Acustica, per “dispositivi sonori sperimentali” e altoparlanti, è uno dei più radicali e straordinari esempi della ricerca sonora di Mauricio Kagel.

Nei suoi continui tentativi di sfuggire ai vincoli e alle convenzioni della performance musicale tradizionale, Kagel ci guida in un mondo sonoro generato da strumenti esotici e invenzioni surreali.

Lo strumentarium di Acustica è immenso: va da strumenti di tutte le culture e di tutte le epoche storiche fino a invenzioni dello stesso Kagel, tutte notate meticolosamente.

Alcuni esempi tratti dalle note alla prima incisione, quella ormai fuori catalogo e rimessa in circolazione da AGP da cui potete scaricarla anche in formato FLAC (compressione senza perdita):

  • Nail-Violin, uno strumento a frizione inventato alla metà del 18° sec. in cui delle barre di ferro di egual diametro ma differente lunghezza vengono messe in vibrazione con un archetto
  • Roundpeg-Violin, come sopra, ma con barre di legno
  • Scabella, sandali rumorosi che venivano indossati dal direttore di coro nell’antica Roma
  • Hinged-board (Crepitacolo), un piatto di legno a cui sono attaccati vari pezzi di metallo che agiscono da batacchi quando il piatto viene agitato
  • Linguelle metalliche messe in vibrazione da un albero a gomiti
  • Puntine di vario tipo per esplorare approcci devianti alla bassa fedeltà: es. un grammofono in cui la puntina è sostituita da una lama di coltello infilata in un barattolo di latta
  • Megafoni di vario tipo
  • Soffiatore incrociato per la modulazione timbrica delle pagine di un libro
  • Palloncini usati come risuonatori negli strumenti a fiato oppure come riserve d’aria
  • Pipe-branch, un lungo tubo collegato a canne d’organo, alimentato da un cilindro pieno di aria compressa
  • Sordine per strumenti a fiato dotate di altoparlante collegato a un registratore su cui sono incise note di strumenti a fiato

Il brano è costituito dalla sovrapposizione di due diversi piani:

  1. un nastro pre-registrato a 4 canali composto principalmente da suoni elettronici, ma anche strumentali e vocali non modificati
  2. le azioni degli strumentisti in numero variabile da due a cinque.

Oltre alle indicazioni per costruire gli strumenti, la partitura è composta da 200 schede (filing cards: le schede degli schedari) ognuna delle quali reca nell’angolo in alto a destra il simbolo dello strumento utilizzato.
L’ordine delle schede è completamente libero, ma l’azione indicata su ogni scheda è descritta con precisione. Anche il comportamento degli esecutori e la loro espressione facciale è dettagliata sulle schede. Gli esecutori decidono in che ordine utilizzarle, così come i loro tempi di entrata.

Nell’incisione pubblicata da AGP, registrata a Colonia nel 1971 sotto la direzione dello stesso Kagel, le prime due parti sono live e comprendono cinque esecutori e il nastro, controllato dal compositore. Le parti 3 e 4 sono un assemblaggio effettuato in studio. Non ci si aspetta che vengano ascoltate di seguito.

Gli esecutori sono: Christoph Caskel, Karlheinz Böttner, Edward H. Tarr, Wilhelm Bruck e Vinko Globokar.

Miya Masaoka

masaoka laser kotoMiya Masaoka presenta se stessa come

musician, composer, sound artist – has created works for koto and electronics, Laser Koto, field recordings, laptop, video and written scores for ensembles, chamber orchestras and mixed choirs. In her pieces she has investigated the sound and movement of insects, as well as the physiological response of plants, the human brain and her own body. Within these varied contexts her performance work investigates the interactive, collaborative aspects of sound, improvisation, nature and society.

In effetti è attiva in molti campi cha vanno dalla musica per koto (anche elettrificato e in versione laser), alla musica per ensembles, al field recording e alla sperimentazione con piante e onde cerebrali, come potete vedere guardando i suoi lavori.

Qui vi presentiamo un estratto da For Birds, Planes & Cello. Come dice il titolo, si tratta di una composizione che utilizza una serie di field recording di aerei e uccelli. I due strati sonori sono mediati dal violoncello che agisce come elemento unificante. In questo estratto di 5 minuti (l’unico liberamente disponibile: il CD è distribuito dalla sua etichetta SolitaryB), l’azione del violoncello è limitata a lunghi suoni, più o meno armonici che si pongono come trait d’union fra le due registrazioni.

Hammerklavier

biasioniNo, non si tratta della sonata 29 op. 106 di Ludwig Van, ma di un recente lavoro elettroacustico di Massimo Biasioni, qui in versione Jekyll & Hyde.

Il brano, originariamente quadrafonico, è basato su campioni registrati all’interno di un pianoforte a coda. Lo strumento non è suonato in maniera convenzionale, i campioni sono stati ottenuti percuotendo, pizzicando o sfregando con oggetti le corde e il corpo dello strumento, allo scopo di ottenere le risonanze del pianoforte piuttosto che suoni con altezza definita.

Il mezzo elettronico è stato poi utilizzato per analizzare e risintetizzare tali suoni complessi, estraendone di volta in volta determinate caratteristiche, esplorando la zona che va dal rumore al suono intonato, modificando l’attacco del suono su modello di una corda pizzicata, disponendo infine il materiale derivato nello spazio quadrifonico e assemblandolo lungo lo spazio temporale allo scopo di costruire un forma organica.
I software usati sono Max/MSP e ProTools. La durata è di undici minuti.

Qui lo ascoltate in streaming (att.ne: inizia molto piano). Potete scaricare l’intero CD “Inside the instruments (l’instrument outragè)”, con altri 4 brani, dal sito dell’autore.

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.

Soft Morning, City!

Un altro brano di Tod Machover dopo Light.

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

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.

Amok!

Un’orchestra di gamelan campionati è quanto esce dalle mani di Evan Ziporyn, compositore americano nato nel 1959, che si dice fortemente influenzato dalla cultura balinese.

Il brano, in 6 movimenti, si intitola Amok! ed è del 1997. L’autore scrive

[Amok!] uses sample technology and the incredible virtuosity and dedication of the musicians to create an impossible musical landscape, a virtual gamelan and then some. Our voracious sampler eats up the whole gamelan and spits it out again, with chromatic gong scales, gigantic gangsa chord-clusters, six reong sections in different keys. Robert Black’s effect boxes and triggering devices allow his bass to match the 25-piece gamelan blow for blow. Melodies begin in the gamelan and find themselves someplace else; simple bass melodies, transformed by delay and harmonization, find their way to Bali and end up sounding almost traditional. The technology makes anything possible with enough megabytes of memory, and the exhiliration this creates is matched only by the terror of figuring out what to do with it. As soon as one abandons the safety of traditional form, western or Balinese, what is to be done? Nothing but to run amok and see what’s left standing when the smoke clears

Seroton

This new sound output [Seroton EP] of Sascha Neudeck (biochemist and musician, based in vienna) is to carry out a test by the idea of different drone-interpretations. It is more a collection of different quotations in doing with such these topics. The result is quite different to his previous work, which was more noise- and random-oriented. This new section is quite a try to arrange such these things – from totally abstract elements to poetic narrative parts. Different ideas come out from an abstractness and get into an often sparely melodic part – otherwise a changeover from the lightness of sound into a deep and noise drone, which is interrupted by fragement spikes of sound. Neudeck is working only with software, sinus generators, self produced sound equipment and lately with the sidrassi organ (totally crazy tool). So I am often surprised by the result, when it sounds like a field recording. But when I see, how he works in his nerdy laboratory, I understand that his output can irritate.
