Façades is IMHO a fascinating piece, although this upload may give quite a poor idea of it. It's typical Glass music, rather sweetly dark, with a flute melody over repetitive and obessive motorike strings. It could evoke something like the story of a beloved and comfortable world going inevitably to its end.
, we have first the strings restless motive, and then the "root" of the piece with a slow flute melody which will be developped later
, music becomes more animated, with sweet flute scales
: an animated section with flute whirlings
a progressive return to calm...and to the void.
Façades was composed first for a kind of chamber ensemble (strings, piano, saxophones, flutes, synthetiser). Then Glass transcribed it for orchestra and also for flute and piano.
I used here the version for flute and piano because there was no transcription to write down : organ right hand for the flute, organ LH for the piano part RH, pedal (coupled, without stops) for the piano LH. Warning : there are some phrasing subtleties which are not properly rendered, for instance a bar where : 6=1+5 at RH, while 6= 2x3 at LH and 6=3x2 at pedal.
The Annaberg Walcker is used because it has both a strong and singing flute on I and a wealth of string tone stops on III.
