12 pipe panflute tuned to the "Mojave" scale (Natural minor, Melodic Minor (Descending) Scale: semitones 2-1-2-2-1-2). The low note is D4 (whole step above middle C on a piano). The panpipes are around 11 inches in length from top to bottom of the longest pipe. 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.
