科学如诗：声学与现象
THE POETICS OF SCIENCE: phenomenology and acoustical occurrences

“……在2007年北京现代音乐节, 中央音乐学院邀请了Alvin Lucier……他的作品《为脑波和打击乐而作》……是通过脑电波产生的一种特殊声音的现场表演，这部作品是他用这种方法创作的第一部作品。而这种所谓的生物刺激在Lucier后来的创作跟表演中都起着越来越重要的作用……

“……In 2007 Beijing modern music festival, Central Conservatory of Music invited Alvin Lucier……Music for Solo Performer for Enormously Amplified Brain Waves and Percussion……was the first piece to feature sounds generated by brain waves in live performance and the biological stimuli played an increasing role in Lucier's subsequent work……”

我觉得我正在尝试着让人们再次拿起贝壳放在耳边，倾听大海的声音。

音乐其实是自然的声学现象，即声音的表现方式，声音的自然存在。而所谓制作音乐，其实就是以声音现象为基础，揭示声音的本质在自然界传播的过程。

‘I guess I’m trying to help people hold shells to their ears and listen to the ocean again’

Music about natural acoustical phenomena; the way sounds act, the way sounds ARE. The phenomenology of sound and the revelation of its natural characteristics and processes are music-making.

Alvin Lucier is a batman. Why I say it? In his music, he is always fightting with "feedback". In 2007 Beijing modern music festival, Central Conservatory of Music invited Alvin Lucier to give a lecture. Alvin Lucier marked a new epoch in body language of performing arts. He uses dynamic-media convey visual-imagery in sound and makes people through his music evoke a natural view in brain. Some other people already talk a lot about his piece, I Am Sitting in a Room, so I will talk about his breakthrough composition, Music for Solo Performer for Enormously Amplified Brain Waves and Percussion. It was the first piece to feature sounds generated by brain waves in live performance and the biological stimuli played an increasing role in Lucier's subsequent work, most notably through his notation of performers' physical movements.

Everyone's body have magnetic field when people think, the magnetic field will change, became a biology electric current through magnetic field and we call that brain wave. Animals might have the same alpha wave came from human being. Is it possible we could have a real “three blind mice” ensemble?

I never thought about someone could use his brain wave to compose a piece. It reminds me a completely difference thing: Schumann Resonance. It is a set of spectrum peaks in the extremely low frequency (ELF) portion of the Earth's electromagnetic field spectrum. Schumann resonances are global electromagnetic resonances, excited by lightning discharges in the cavity formed by the Earth's surface and the ionosphere. I am wondering if we also can use this theory to compose a piece?

In my opinion, theses words are not only the course summary, also the good way to absorb the  important theory that beyond commercial music making. The courses in the past, we were just listening to Martijn, but today we had some interaction during the lesson. I think the course is becoming more and more interesting. After we got the meaning of some theory, new knowledge easier for me to accept.

To the word "Alpha", I have to talk something about the video Martijn shown to us. It uses the alpha signal from the brain wave of the sleeping man (Alvin Lucier himself) on stage to control the resonant frequency which can produce resonances with percussion. The performance gave me a lot of inspirations and questions. Our brain is so complicated and how can Lucier to do that amazing work. I think he must use many physical theory into this performance and It is necessary to study some knowledge about physical.
