Discover the exciting world of electroacoustic music and learn to make music with sounds.



Listen to these sounds:

New Sound One

How would you describe this sound?

New Sound Two

Does it sound like anything that you have heard before?

New Sound Three

What is this sound? Where did it come from?

  • Do they sound like anything that you have heard before?
  • Where did they come from?
  • How were they created?


Recording technology captured the sounds, and sound editing programmes on the computer were used to transform them.

(Curious about EXACTLY how each of these sounds were made? Click here for MORE information:)

New Sound Two: Was made by transposing an original recording of birds and adding reverb. The recording of birds was transposed upwards to eight times its original. A highly reflective reverb was then added to make the sound blur.

New Sound Three: Was made by using time stretch and transposition. The original sound (of a car driving past) was taken and stretched to make it twice its original length and half its original pitch.

Later, we can combine and organise these sounds to create pieces, for example:

Except of a piece

This is a short clip of a piece made by combining and organising some of the sounds from above. All of the sounds in this clip can be found as part of the External sound card pack in the Compose With Sounds software.

Appreciating All Sounds

One of the Futurists, Russolo, LuigiItalian artist and writer who wanted to make music with all sounds. In 1913 he wrote the 'Art of Noises', a leaflet arguing for composers and musicians to use all sounds, especially noise sounds.More infoLuigi Russolo argued that most music was only made with about four or five different types of sound:

    • 弓奏乐器
    • 拨奏乐器
    • 铜管乐器
    • 木管乐器
    • 打击乐器






Listen to some examples of sounds from each category. Which collection of sounds do you prefer? Why?

Orchestral Sounds


Discrete and contained pitches


Steady pitch sound


Mainly only used for emphasis.


Steady pitch sound.

All Sounds


Complex vibration and beating


Different textures


Solid thump


Many small sounds with depth



Schaeffer, Pierrea radio engineer and composer who founded the group that became the GRM (Musical Research Group). He studied sounds and developed the idea of Musique Concrète.More infoPierre Schaeffer was working as a technician at the French radio (RTF) in the 1940′s when he became fascinated with the possibilities of recorded sound. He recorded sounds onto vinyl disks (like LP records) and then explored the transformations that were possible: for example: reversing sounds, transposition, time-stretch and loops.

Using these techniques he invented a style of music which he called Musique ConcrèteA term created by Pierre Schaeffer in 1948 to describe his new music, which started from the concrete sound material, from heard sound.More infoMusique Concrète

Summary: 新音乐的可能性

Recording technology changed music forever. Any sound can now be captured, controlled and organised to create new works.

It allows us to do things with sound that were never before possible. And lets us break free from the limitations of tradition.

Computers give everyone access to tools for sound transformation and organisation, opening up the full world of sounds to all.



The majority of music that we hear would not exist without the technology of recording.


In 1913 Luigi Russolo published a leaflet called ‘The Art of Noises’ in which he called for a new music. – Read his leaflet here.
