Missa Puerorum (Kleiner Und Leichter Messgesang). Par RHEINBERGER JOSEF GABRIEL. Of Josef Rheinberger's eighteen masses, five are for unaccompanied voices, four with accompaniment by a small instrumental ensemble and nine with organ. Among the last group the 'leicht ausführbare' [easy to perform] works take a special place: Considered by their composer as purely 'utility music', they achieved great popularity during his lifetime and soon became part of the standard repertory of small church choirs. / Messe / Répertoire / Solo S (Choeur S) et Orgue
