`Spiegel im Spiegel` is a well-known example of Arvo Pärts Tintinnabuli style and has been used in many films.
Arvo Pärts Spiegel im Spiegel illustrates his creative principles: above a permanent flow of chords on the piano, the cello unfolds acantilena in long note values, which grows out of succinct steps. This cantilena spins out sweeping, chorale-like arches and spreads itself out more and more. It thus gives rise to a new architectonic configuration which, like a mediation chapel, stimulaties reflection, prayer or the desire for redemption. Jürgen Köchel
