Pierre JANSEN (1930-2015). Autograph musical manuscript, ...Un voile qui s'illumine de soi..., rêveries pour 24 instruments à archet; 124 sheets 35 x 27 cm (cut-outs at bottom of plate). Piece for string orchestra: violins A (4), B (4), C (6), violas A (2) and B (2), cellos A (2) and B (2), double basses A and B. The work has 100 bars, and begins very slowly. It is dedicated " for André Girard and the Orchestre de chambre de l'O.R.T.F. ". The title is borrowed from Gaston Bachelard's L'Espace onirique (the quotation appears on the enclosed printed title page): "Thus dream space has as its background a veil, a veil that illuminates itself in rare moments, in moments that become rarer and more fleeting, as the night penetrates more deeply into our being." The manuscript is carefully written in Indian ink on tracing paper with 30 lines.
