D4 (lowest note) Panpipes in the minor pentatonic scale (9 pipes). Decorated (Full Color Sandstone) with van Gogh's "Starry Night" painting. Color materials are water reactive! Seal with water-resistant finish (e.g., shellac, polyurethane) if you wish for this to be more than decorative. The pipes are tuned to the indicated scale, and thus can be played.
