Par PART ARVO. Psalm 133, a pilgrim song of David with three verses, is one of the short psalms. It describes the blessing of brotherly unity: 'Behold, how good and pleasant it is for brethren to live in unity!' Arvo Pärt set this verse to music in a brightly reflective choral piece and dedicated it to his long-standing music editor at Universal Edition, Józef Stanislaw Durek. / Musique contemporaine / Répertoire / Choeur [S,A/Ct,T,B] ou Ensemble Vocal [S/Ct,A/Ct,T
