Framed by two the sound space striding and combining pieces Introductions consists of a total of eighteen short and shorter compositions, which always refer to a coming one which then doesn’t appear. Each of the miniatures seems like a redemption of the promise done within the preceding bars so that casually a multiply interlocked form arises: the "first theme" turns out to be a further "introduction". Not only progressing in slow tempi and in their unconcluded provisionalness rather less working in itself, the mouvements, held together by fermatas and got going by frequent tempo changes, seem to stand unconnected next to each other and appear to raise the question whether the actual resounds only into us.
