Tintinabulum

Barley, a dog, ponders a sonic sculpture consisting of sheet metal but into bulbous shapes that hang within a red framework.

I’m a big fan of this sculpture. As it was explained to me, the harmonic profile of a traditional, 3-dimensional tubular bell can be closely approximated by an appropriately-shaped flat sheet of metal. And sure enough, if you strike any one of these bits of sheet metal, it rings with a pleasantly sonorous note on a 12-tone scale (with the 13th note providing the octave). I always make sure to do so when I walk by, although Barley gives the impression of not being as big a fan of its musical potential as I am.
