Resources you might find interesting to supplement the lecture on The Butt Music from Hell, which I’ve given in multiple venues, most recently as a DEAR Luncheon Lecture on May 18, 2023. Most are links to websites I ran across.
Hieronymus Bosch and his work
- Gallerix.org Hi-res images of Bosch paintings and drawings
- Bosch at the Prado in Madrid
- Bosch Art Center in ‘s-Hertogenbosch (You’ll need to have your browser translate from Dutch)
- House of Bosch in ‘s-Hertogenbosch – His studio, newly restored and open to the public (in Dutch)
- ‘s-Hertogenbosch Stories from their municipal website (in Dutch)
Period instruments and modern replicas
- Instruments page from Musica Antiqua at Iowa State
- Harry Wass Hurdy Gurdies Facebook page
- Hell Harp thesis by Johannes Bergmark (no kidding!)
There are lots of videos resources on plainchant notation, most of which are likely more extensive than you’d like. Here’s a document that is pretty accessible, as you might gather from its title.
- Idiot’s Guide to Square Notes from MusicaSacra.com

Al’s transcription of the Butt Music from Hell
Other renderings of the Butt Song, all derived from Amelia Hamrick’s transcription
- Original Amelia Hamrick video made just after her blog entry exploded
- Elaborate arrangement of Amelia’s transcription – Very pleasant
- Metal version (of course there’s a metal version…)
- Vocal “arrangement” with less-than-profound “lyrics” tastefully buried in reverb
