Nothing about practice in this post, but you can bet it took a lot of practice of all sorts to shoot this very cool video from musician Nigel Stanford. In fact, it took months of preparation, and 2 days of shooting in a Brooklyn warehouse.
Composers use lots of ways to create compositions. Stanford’s use of these physical properties of sound (and frame rates of cameras) to create a piece is fascinating. Check out the “behind the scenes” vids for details on these experiments with sound.
