In a way, he went even further.  He wanted Anne-Sophie Mutter to play
Chain 2 and the Partita in the same programme and he decided the two
concertante pieces needed to be separated, and yet linked, by suitable,
and therefore contrasting, interlude music.  His resulting, slow-moving
"Interlude" is written for orchestra and lasts just over six minutes.
The predominant contrapuntal strings sing softly overall, with twinkling
highlights from the winds.

Although he dedicated his 1989 Interlude to Paul Sacher, it so drew its
title from what he wished its function to be, and the first performance,
as part of what was then virtually a triptych, took place in Munich in
1990, with Mutter, of course, and Lutoslawski himself conducting the
Munich Philharmonic.  Interestingly, the order chosen was not chronological:
Partita (1988) - Interlude (1989) - Chain 2 (1985). It works very well.
