Cedrik Fermont is a composer, musician, mastering engineer, author, independent researcher, concert organiser, curator who operates in the field of noise, electronic and experimental music.

In his lecture, he told a lot about his own travel and the problems and stories found in his travel. He has been to many countries and regions to give some speeches, lectures and seminars. In that era when there was no Internet, he traveled around the world to visit various countries to promote some western music types. Although he encountered many difficulties in this process, and some locals did not think there was experimental and electronic music, he insisted on exploring and discovering.

He said he was happy to grow up in an era without Internet, technology and computer, because he can use his creativity to create his own things. For example, if he wants the sound of a river, he will record the sound on the spot instead of downloading things on the Internet. His passion for sound art and music makes me very admire, because in that era without the Internet, Cedrik can break through some difficulties to create his own unique things.

Sam Auinger is a sonic thinker, composer and sound-artist.He cooperates with urban planners and architects, gives lectures and often participates in international seminars on urban planning, architecture, media and senses.

In the lecture, Sam talked about many things in the past, such as what inspired him to engage in sound art. I remember what he said that it was possible to distinguish which model it was by the sound of the car engine. This was very interesting, just like when I was a child, I listened to the calls of various birds in nature class to distinguish what birds it was.

The acceptance of sound has a certain relationship with temperature, age, gender, culture and so on. Therefore, everyone’s feelings for the sound he hears and his feelings for the sound will be different.

Blue Moon is one of project of Q+A. The three “tuning tubes” installed in the harbor create melodies and chords based on the sound of the city, such as jet, helicopter, wave, ship,etc. The sound is played through five “Cube” speakers arranged in an arc on the square to create a real-time and harmonious urban sound area. As the tide rises and falls, the combination of tuning tubes changes the key, adjusting with the orbit and period of the moon. Nature and harmony are injected into urban public space.

Finally, I tried the pebble experiment. When I hit the window in my room with a small ball, the sound of hitting the center of the glass and the edge of the glass is different. I was thinking it might also have different quality of every part of the glass, but this experiment is very interesting. Then I tried to drop the ball at different heights and found that when I put the ball high, the tone of sound made more high. When the ball falls at the same height, the sound on the marble surface is higher than that on the wooden floor.
