Sei Miguel: Original Copy

Sei Miguel, the trumpeter and composer who died in 2025, wanted his fellow musicians to play dynamics and tensions that standard notation had no symbols for. So he invented his own: diagrams poised between drawing and writing, symbol and word, which Culturgest says were "devised to offer guidance in the dark".

Original Copy gathers a broad selection of these scores in Gallery 3, the small former bookshop. You walk in to look at instructions written for players rather than for an audience. The pages sit behind glass on a shelf, and curator Bruno Marchand says the chance you take them for drawings is the point. The title is the method: he amended and re-photocopied each page until the piece worked, so there is no original. His partner, Fala Mariam, says the roughly 50 pieces were kept in a tupperware.

Admission is free. Birgit Ulher and Joe Morris play a free concert of about an hour in the gallery foyer on Saturday 12 December at 6pm, limited to capacity.
