Transcript of Meng Qi @ CCOM Digiscore Workshop Lecture: The Complete Design Concept of Horizon

video upload by 合成少数派 Synthesis Minority

"During the Digiscore Workshop at the Central Conservatory of Music, where I was invited by Professor Ken Fields, I engaged in a conversation with everyone about musical scores and instruments. We explored the relationship between musical instruments and people, as well as the dual-natured thinking that Trent and I condensed in our musical instrument work, "Horizon." The students at the Conservatory posed many constructive questions, and I truly enjoyed the intellectual exchange with everyone. Here is the lecture transcript, and I hope it is useful to many others."
