THE BLIND MAN (1979)

for two-channel tape based on a poem and reading by Norbert Ruebsaat

The Blind Man is a realization of a poem by Norbert Ruebsaat that uses a reading and improvisation on the text by the writer as its basic source material. Additional environmental sound material from the World Soundscape Project Library is also used, sounds that are largely metallic: bells from the Salzburg Cathedral (with which the piece opens) and the Storkyrkan in Stockholm, and a series of locks and heavy doors from the vaults of the Vienna State Library.

The piece was realized in the extremely well-equipped Studio Charybde at the G.M.E.B., Bourges, France, during the first 5 days of a two-week work period (Ascendance was realized during the second week), as the result of a commission from the GMEB, based on the composer's prize winning Sonic Landscape No. 3 (computer music category, 5th International Competition of Electroacoustic Music, Bourges, 1977).

Norbert Ruebsaat recorded the poem in the Sonic Research Studio, S.F.U., on his own (the 4th and last reading was the one used), plus a fascinating improvisation on the words and phrases in the poem, giving the composer more than enough raw material to be used, as well as significant insights into the sonic images in the poem as conceived by the author. The reading clearly divided the poem into 5 sections, each with its own imagery and mood. The two bell sequences (Salzburg and Stockholm) were dubbed from the W.S.P. tape collection, having been originally recorded in 1975 during the group's European tour. The spectral richness of these sounds made them ideal material for use with the extensive filter banks in the studio, as well as suitably contrasting timbres to the voice. The original Salzburg recording, which featured the 10,000 kg Salvatore Mundi bell, was used in its entirety and hence determined the length of the first section, from the first ring to the last (heard in its muted filtered version at 5:50-6:00). The original recording of the Storkyrkan bells in Stockholm followed the recordist from outside the church as he approached the entrance, and then into the interior, thereby producing a strong peak in the spectrum at the closest distance. This sequence is not heard in its original version in the piece, but rather the heavily filtered version establishes the ambience of the last section of the piece.
