In summer 2005 I was the orchestra director for MTG's Sweeney Todd. I reduced the orchestration to only five instruments: flute, clarinet, violin, cello, and keyboard (aka Pierrot Ensemble). This enabled us to fit on a tiny stage with a large cast, and not drown them out (the singers were not amplified). It also allowed me to use exactly the same excellent ensemble for every single performance of a 3-weekend run, which would not have been possible even with the "official" reduced orchestration.

The keyboard used only real keyboard sounds (piano, pipe organ, and of course harmonium). The pipe organ helped to make up for the lack of brass in the climactic scenes.

I've provided arrangements for several other productions since then, often with custom revisions for their unique needs.

If you're doing Sweeney Todd in a small space and are interested, please email me.
