A Strange, Overpowering Feeling - Whimsically Macabre

A piece in 5/4 that uses different versions of only two chords, F and GbMaj7/Bb. It also has 2 different 3-note isomelodies over the repeating 5-note accompaniment pattern that eventually combine into an 8-note isomelody. The title is a phrase from The Listing Attic, by Edward Gorey.
