Autoharp Beer

Anyone who has spent time with beer knows that glass beer bottles make a chimelike sound when tapped with a hard utensil. Autoharp beer capitalizes on this for musical effect. The beer bottles are printed with lines on the side corresponding to levels of beer. The drinker(s) drinks down each beer to the correct level, then arranges them in a line according to the instructions. Runninga fork or knife across the bottles then generates a chord. The chord can then be changed by drinking a little more beer out of certain bottles.

It occurs to me that this could be accomplished using preprinted level stickers, which could then be affixed to bottles of any type of beer. Or wine! The stickers would be reusable as well.
