In memoriam Mátuás Seiber

Instrumentation. 4 flutes (1-4 also piccolo). 4 oboes. 4 clarinets (4th also clarinet Eb). 3 bassoons. Contrabassoon. 6 horns. 4 trumpets. 4 trombones. tuba piano (2 players - if possible percussionists). 14 first violins.14 second violins. 10 violas. 10 violoncellos. 8 contrabasses (1st, 2nd and 3rd with fifth string).

The clarinets, clarinet in E, and horns are notated as they sound. Piccolos, contrabassoon and contrabasses are notated in the usual octave transpositions (even the harmonics in the contrabasses). The bar-lines in this piece are purely a means of synchronization of the individual parts and an aid to temporal articulation. There is no such thing as a beat in the sense of metrical pulsation. Therefore, the be ginning of a measure does not mean an accentuation. The piece should be played completely without accent, with the exception of a few places which are specially marked. Besides the usual mute, "scraps" (a soft cloth, tightly stuffed into the bell) are required for the horns (see cue J).
The piano is to be placed as near as possible to the trombones. The top is to be removed. Before beginning the piece, the piano pedal is to be depressed and secured with a wood wedge or a suitable weight. The piano part is to be performed by two players standing as follows.
If possible, two pianos should be used instead of one. In this case, the second player stands at the second piano in the same manner as the first player at the first piano.
