The main idea behind the piece is the creation of dialectic situations within the mon­o­phon­ic limitations of a solo instrument. The already rather versatile dialectic capabilities of the pipe organ are further increased through a quintet setting:
a) a trio of organists: one player treating the instrument at the organ console or keydesk, the other two in its interior;
b) two extra instruments: contrabassoon and tuba complementing the larger bass pipes.

Timbrally, the piece investigates different levels and qualities of the organ tremolo. The old principle of the tremulant device (French: “tremblant”), i.e. the production of fluctuating sounds by manipulating the mighty air column inside the organ pipe, is extended and intensified with the help of preparations. Different external materials and objects, like sheets of paper, plastic and aluminium foil, rubber balloons, animal calls and party horns, are attached to a small selection of organ pipes, esp. larger bass pipes and louder reed pipes.
