What is Electroacoustic Music ?
- Electroacoustic Music is concerned with the exploration of sound.
- Being categorized as Music, one naturally draws on views held
about the centuries of music preceding this present century.
This is unwise.
You must adopt a new method of listening.
- Electroacoustic Music is structured by the "concrete" nature of sounds
themselves.
- For the most part, this music exists entirely on tape and is normally
diffused (performed) over a multi-channel loudspeaker system (like BEAST).
- Electroacoustic Music is that which uses technology as a tool and
gives the composer access to virtually any sound.
- There are many "brands" of music now that involve technology. Categorizing
Electroacoustic music to any one specific use of technology would be wrong.
- Electroacoustic / Computer Music / Acousmatic ?
- This final definition compares just three names that composers use
to describe their music. Computer Music can normally be attributed to those
specialising in synthesis and algorithmic composition. The term Acousmatic was
first used by the followers of Pythagoras.
When lecturing Pythagoras sat behind a screen so that
content was heard but source was not seen. Acousmatic has been taken
up by composers most notably from France and Canada who
suggest that we detatch cause from sound (car, voice, sea "sounds like a
bird" etc). Electroacoustic is an amalgam between Electricity and Acoustic
- how sound (pressure variations in the air) gets converted to electricity
by microphones, gets recorded and treated, and is finally converted from
electricity to pressure vibrations in the air by loudspeakers.

Why Electroacoustic music ?
We know for a fact that our ears can listen to combinations / articulations of
ANY sound between 20 and 20,000 Hz so why deny our ears the ability to
function at their best. Our mental faculties will be tested to
the full in order to process this information and this can only be an
improvement.

When did it all begin
- From the early experiments by people like Russolo, Martenot, Theremin and Varese
- Pierre Schaeffer, working
in Paris around 1950. It was Pierre Schaeffer who created musique concrete,
recorded sounds from the environment / the studio used to create music.
His first work for this new medium was "Etudes aux chemins de fer".
His work was criticised because of its sound association. This focused his
research into l'objets sonores and eventually to the idea that there
should be a solfege for these sound types which enabled description
of sounds in terms of aural phenomena.
- At the same time in the West German Radio electronic music was being
composed using only analogue synthesis (sine tone generators with serial
control over duration, intensity, frequency, and timbre - the superposition
of sine waves to form composities).
The early electronic studies of
Stockhausen most clearly represent this approach.
- The differences between these two types of music were clear both in style
and sound. Through the increases in technology the two schools have merged
and yet one still sees a divide between the work (research and composition)
of IRCAM and GRM for example.
- The problem of association remains to this day. I believe that incorporating referential sounds (environments, human utterance, text), create extreme
problems for the composer as they can often be heard 'extra-musically'. It's
a problem to be looked at. (Michel Chion - and the idea of melodrama for
example). That's not to say that abstract, 'synthetic' pieces are easier, its
just that they dont carry any extra baggage with them. References can be
a point of contact or a barrier to comprehension.

The Basics
from early tape techniques to spectral design on the micro and macro levels !
Then:- with tape recorders one could play sounds faster, slower,
forwards, backwards, loop a small piece of tape so that it repeats itself,
mix two or more sounds depending on the number of tape machines, create delays
between the heads, simple flanging etc.
- Alongside being able to record sounds (natural sounds) one could create
sounds from their very beginnings ie Sine waves. This is where the serial
school of composers found the ultimate in disinterested composition.
Absolutely everything could be serialised. With oscillators you could control
speed, wave shape and then start synthesis by adding waveforms or multiplying
them together (modulation).
Now- With digital techniques one can perform all the above.
Composers still do pitch changes and reverse sounds just like in the 60's.
This could be an answer to why some music today sounds similar to music then.
(The deeper reason is that there is a common language - like the tempered scale
- between eamusic now and eamusic then.)
- Composers can now treat sound with such finess that listening must
be directed "spectrally": how a sound lies within the audible frequency
spectrum.
- One can now change the pitch of a sound without changing the speed and
change the length of a sound without changing the pitch. One can graph
spectra (the sonic quality) of one sound onto another. And so on, the
list is endless.

Composers
There are so many composers of electroacoustic music that this section must
concentrate on those that are most enjoyed by the author of this document.
I follow with interest the composers entering music into the following
competitions
- Borges
- Noroit
- Prix Ars Electronica
- Musica Nova
- Luigi Russolo competition
and of these communities / societies
- GRM - Groupe de recherches musicales, Paris
- IRCAM - also Paris
- SONVS - Lyon
- the CEC - Canadian Electroacoustic Community
- SAN -
the Sonic Arts Network of England
Some composers have web sites (see the composers corner). As many British
composers are resident lecturers at Universities, their details can be found
by going to a university music department's site (see hotlist). However, here
is a list of composers that would form part of a history of electroacoustic
music to name but a few.
- Pierre Schaeffer
- Edgard Varese
- John Cage
- Karlheinz Stockhausen
- Pierre Boulez
- Philippe Manoury
- Kaija Saariaho
- Francois Bayle
- Bernard Parmegiani
- Francis Dhomont
- Michel Chion
- Chrisitian Calon
- Robert Normandeau
- Ake Parmerud
the music of the GRM can be found on their own label. The label Empreintes Digitales carries many excellent examples of electroacoustic music (see hotlist for Empreintes' page).
here are some composers living and working in England
-
Denis Smalley
- Jonty Harrison
- Simon Emmerson
- Trevor Wishart
-
Alistair MacDonald
- Andrew Lewis
- Javier Alvarez
- Alejandro Vinao
-
Mathew Adkins
- Joe Hyde
- Pete Stollerey
I am sure to have missed other "important" composers so let me know

The listening experience
In listening to a work of electroacoustic music we make judgments based on
gestalt principles, such as proximity, symmetry and continuation.
If sounds are close together they tend to get grouped together. The more
symmetrical an object is the more likely it is to seen as a figure. This
visual statement translates to the more a phrase or sound has a start and
a finish the more it is heard as a gesture. Symmetry in sound can be found
between the three dimensions of frequency, amplitude and time.
There is a structuralist approach to electroacoustic music which says that
there is musical structure at all levels. Being time based
we are continually defining something by what it is not as we hear more in
a piece. Therefore our short term memory must play a role in securing
sounds that are vital and letting less important sounds pass away.
The "newness" of composers' soundworlds is more than "sensation". There are
deeper levels of meaning to be perceived.
Electroacoustic music does not have to rewrite its own language for each piece
and should not be dismissed for baring resemblance to anything.
It is the resemblances within itself that are the most important.
What is it in a sound simple or complex, that attracts our ear so that
we attend further ? Is it all based on our experience or on other more
objective values like volume / spectral content / human utterance ?
Is there a universal "liked" sound-world ? The odd thing about electroacoustic
music over the past few decades is that the form has not really changed, only
the content (the sounds used). If anyone has comparative sonogram analyses of
works from the past 30 years that can back up this statement I would be
interested. For all the diversity we can achieve it is remarkable to hear the
similarity of composers' music.

Sound Diffusion - The performance practice of electroacoustic music
For the majority of electroacoustic music, a 2-track stereo master is used
to diffuse sound in a space. In the case of BEAST, our 2 track master is
'split' many times into a custom desk such that each fader controls an
individual loudspeaker. From experience BEAST has grown to a large selection
of loudspeakers which can be effectively placed in a hall to orchestrate
a piece of music on tape. These speakers, positioned correctly can also
compensate for many designs of theatre allowing one the chance to place
sound sources in new places whilst at the same time ensuring adequate sound
coverage for the maximum number of audience.

How to become involved
For those on the web who have not heard Electroacoustic music, try finding
some concerts. Follow links to other University music departments.
If what you read about BEAST interests you then you have to attend concerts.
Recordings are not the same. There is normally nothing to look at so shut
your eyes to allow yourself to concentrate more on listening.
As stated earlier, the main places of composition are music departments
at universities. However, electroacoustic composition is reaching ever
wider, from schools onward. With the availability of technology, more and
more people are building studios at home. There is a great deal of software
on the net.
