Trimpin, a single-named German sculptor and composer, created the Sound Arch as part of the Libbey Bowl renovation in 2011. The arch consists of 24 metal tubes of varying lengths with resonators and internal mallet mechanisms that produce melodic sounds similar to a xylophone or chime.

When you walk through the arch, a motion sensor triggers a pre-composed melody to play. The individual compositions vary, meaning that each visitor has their own experience.

Since its installation, there have been many calls to have the sound turned down or off. Neighbours complain, and even performances in the Bowl are impacted. I’ve noticed on my recent visits that the Arch has been silent, so maybe it’s been deactivated for good?
