Tuned Pale Ale is a product by designer Matt Braun. There’s a musical scale down the side of each bottle. You can drink down to a particular level, blow on the rim, and the bottle will produce the note. If you get a few people together with these bottles, you’ll be able to perform a melody. Braun advised that the label serves a two-fold purpose: the product aims to inform users about the musical qualities of existing bottles and makes the bottle a better instrument.
