Pärt's Solfeggio for mixed a cappella-choir - sung on the solmization syllables Do-Re-Mi-Fa-Sol-La-Si - was composed in 1963 and premiered in Tallinn (Estonia) by the Estonian Radio Choir (director: Eri Klas) a year later. Solfeggio (1964) is the only work on this recording which predates Pärt's tintinnabuli period, although the simplicity of its conception - the notes of the C major scale in overlapping sequence and with frequent octave displacement - is entirely characteristic.
