路易吉·诺诺的《为大号和电子音乐而作》
"Solo Tuba and Live Electronics (1987)" by Luigi Nono

“……直到今天上了这堂课我才知道Nono的作品中有电子音乐的元素。他的作品《为大号和电子音乐而作》（1987）非常独特。我不确定这是否是第一部在电子音乐中使用现场乐器的作品，但是我相信它一定对现今的电子音乐产生了深远的影响。今日的科技远胜从前，尽管这部作品使用了极其有限的技术手段，比如混响和延迟，却有令人耳目一新的效果！……”

“……I have never known about Nono could compose electroacoustic music until I had this lesson today. His piece, For Solo Tuba and Live electronics (1987), is very unique .I'm not sure it is the first piece that uses live instrument an electroacoustic music, but I certainly believe it influences electroacoustic music at present. Science and technology of today is better than past, I have to say although this piece used extremely limited method, such as reverb and delay, it did an amazing things!……”

Luigi Nono was an Italian avant-garde composer of classical music and remains one of the most prominent composers of 20 century (wikipedia)

Nono’s music is very quiet and simple; however this idea is throughout his music. Expect “II canto sospeso”, I have never known about Nono could compose electroacoustic music until I had this lesson today.

His piece, For Solo Tuba and Live electronics (1987), is very unique .I'm not sure it is the first piece that uses live instrument an electroacoustic music, but I certainly believe it influences electroacoustic music at present. Science and technology of today is better than past, I have to say although this piece used extremely limited method, such as reverb and delay, it did an amazing things! In this piece, chapter one is my favorite. He used a few rows and each row has a different performance practice, for instance when you play "row number one", you need to play the note and sing at same time; when you play "row number two", you need to play a note just get the valve half pressed and so on. There are seven of rows in total.

In summary, chapter one is a puzzle for me, which was why I like it so much. If I'm a tube soloist, when I play this chapter, it is more like an adventure I have never had before. Seven rows use seven different colors and it does not mean "row number one" has to be played at the beginning. Before he writes his music, he will discuss with someone. It is just like a brain storm. Nono invented a lot new performance practice, so it is also a challenge to the player. There is an interesting thing in the score, you can see a long note its dynamics from "pppp" to "ffff". It is kind of extreme use of dynamic and it is very hard to play. I think it's a dynamic envelope as same as "ADSR"(attack, decay, sustain, release).
