Spiegel im spiegel

Spiegel im Spiegel (German for 'mirror(s) in the mirror') is a composition by Arvo Pärt written in 1978, just before his departure from Estonia. The piece is in the tintinnabular style, in which a melodic voice (operating over diatonic scales) and a tintinnabular voice (operating within a triad on the tonic) accompany each other. The piece is about ten minutes long.
