This work is based on the theme of "cinematic time on film." Suddenly, I noticed the musical scale of the curtain hanging on the window in my room. The film was shot with a modified 16mm camera. The footage even made it onto the soundtrack. On film, the picture and sound are the same and it's perfectly synchronized. However, due to the structure of the projector, the sound reproduction part is separated from the image,. The picture and sound on the screen are out of sync. However, if you organize the preceding sounds into a phrase, the misalignment on the screen appears to be perfectly synchronized.
