Spiegel im Spiegel
Spiegel im Spiegel is a piece of music written by Arvo Pärt in 1978, just prior to his departure from Estonia. The piece is in the tintinnabular style of composition, wherein a melodic voice, operating over diatonic scales, and tintinnabular voice, operating within a triad on the tonic, accompany each other. It is about ten minutes long.
The piece was originally written for a single piano and violin – though the violin has often been replaced with either a cello or a viola. Versions also exist for double bass, clarinet, horn, flute, bassoon, trombone, and percussion. The piece is an example of minimal music.
The piece is in F major in 6/4 time, with the piano playing rising crotchet triads and the second instrument playing slow F major scales, alternately rising and falling, of increasing length, which all end on the note A (the mediant of F). The piano's left hand also plays notes, syncopated with the violin (or other instrument).
"Spiegel im Spiegel" in German literally can mean both "mirror in the mirror" as well as "mirrors in the mirror", referring to an infinity mirror, which produces an infinity of images reflected by parallel plane mirrors: the tonic triads are endlessly repeated with small variations as if reflected back and forth.
In 2011, the piece was the focus of a half hour BBC Radio 4 programme, Soul Music, which examined pieces of music "with a powerful emotional impact". Violinist Tasmin Little discussed her relationship to the piece.

Pärt himself endorsed a recording on the ECM New Series album entitled Alina, recorded in July 1995 and released in 1999. It includes two variations of Für Alina by pianist Alexander Malter, and three versions of Pärt’s Spiegel I'm Spiegel (for piano and violin, violoncello, and violin, respectively). According to the liner notes, the two versions, somewhat like “mood improvisations”, were handpicked by Pärt from a recording that was originally several hours long. The two versions most strikingly differ in the use of rubato and that of the use of the low octave b. Both versions clock slightly under eleven minutes.
