Tuned beer was a fun project to work on, It was part of my thesis as an undergrad. A friend and I collaborated on creating objects that made connections among everyday objects and sound/music.
We redesigned the bottle, label, and six pack, to become a music making kit. The bottle has raised ridges on the side, when played with the cap it mimics the sound of a guiro (a latin percussion instrument). The label has marks on the side that correspond to the notes in the musical scale. The sound is made by drinking until you reach the desired note, then blowing across the top of the bottle to make it whistle. The six pack holder, when turned upside down, is a tongue drum that has six different pitches. We received some good exposure from the project, it was published on many blogs and in magazines, it even led to an appearance of us playing Tuned Beer on The Tonight Show with Jay Leno!
