Unless you're a professional musician you probably don't think about acoustics that often. But every room you walk into (or building, or field) has its own unique sound properties that leave their mark on your voice. This video from Austrian production company Touché Videoproduktion demonstrates this perfectly with a melodic singer who moves from church, to attic, to gym with a clap of his hands. There's even an anechoic chamber in the mix — a type of room used in audio engineering to completely absorb echoes. If the method in the video looks familiar, it's because Touché Videoproduktion did the same with a traveling drum kit last year (embedded below). Let's hope they're building their way up to using even more musicians. Personally, we'd like to see it done with a mariachi band.
