Spiegel im Spiegel (Mirror in the Mirror) is one of the best known and most performed pieces by Arvo Pärt and also one of his last compositions before his departure from Estonia.
The musical material of Spiegel im Spiegel is presented with utmost clarity and strictness. It only consists of the melody of the solo instrument and the three-note piano accompaniment. The structure of the piece follows a strict formula, where no note is left to chance and the piano part is deceptive but clear. It sustains an upwardly motion, accompanying the long notes of the violin. Although major and minor triads are very important to Pärt, here he breaks the conventional harmonies. When the violin plays an F, the piano plays and F major triad. When the violin plays a G, the listener expects a G minor triad, but only the outer voices of the triad remains true to this. The inner voice always acts as a T-voice in F major so it always goes to the nearest available note from the triad. Which constantly obscures the harmony. Whichever note is played, it corresponds to this formula, creating a unique harmonic realm. The very high notes that are appearing are always outlines the F major triad, reminding us of the tonality so somehow always stays true to giving out the main triad. This is a summary of this accompanying part. But what about the melody?
The violin only plays long notes from the F major triad. The beauty of this melody is that it sounds as if it is being improvised on the spot, almost childish like. But of course there is deep pattern hidden inside. It is actually hidden in the title itself. The second note of F major triad, A, serves as an axis and the melodic activity revolves around this centre.
As we progress through the melody, we make progress further away from the centre, moving away, coming towards, moving from and moving towards, creating a seemingly endless continuum. All motions are lined up symmetrical, like an image in a mirror, hence the title Spiegel Im Spiegel. A very simple sounding structure has a very systematic construction behind, a typical example of how Pärt composes.
A reduced version of how Pärt harmonises the notes of the scale. Whenever the melody plays a note from F major scale, it is harmonised by one of these chords in an arpeggiated way.
Additional Note
- Lowest note G in the melody also corresponds to the lowest pitch available for violin. Thinking about the ranges of the instruments is a crucial element when forming structures like this. There is also an arrangement of this piece for solo organ where it is transposed to C major so the lowest note of the piece corresponds to the lowest note of the keys.
