Tintinnabuli (singular. tintinnabulum; from the Latin tintinnabulum, "a bell") is a compositional style created by the Estonian composer Arvo Pärt, introduced in his Für Alina (1976), and used again in Spiegel im Spiegel (1978). This simple style was influenced by the composer's mystical experiences with chant music. Musically, Pärt's tintinnabular music is characterized by two types of voice, the first of which (dubbed the "tintinnabular voice") arpeggiates the tonic triad, and the second of which moves diatonically in mostly stepwise motion.[1] The works often have a slow and meditative tempo, and a minimalist approach to both notation and performance. Pärt's compositional approach has expanded somewhat in the years since 1970, but the overall effect remains largely the same. An early example can be heard in Cantus in Memoriam Benjamin Britten.
