Mass in A major, Op. 126 (Rheinberger)

The Mass in A major, Op. 126, is a choral setting of the Ordinary of the Mass composed by Josef Rheinberger. It is scored for a mixed choir of four voices (soprano, alto, tenor, and bass), organ, and strings (typically violin, viola, cello, and double bass).

Rheinberger composed the Mass in A major in 1881. It is a late work in his extensive catalog of sacred music. The mass is characterized by its lyrical melodies, rich harmonies, and skillful orchestration. It is considered one of Rheinberger's most significant contributions to the repertoire of sacred choral music.

The Mass consists of the traditional five movements:

• Kyrie: A plea for mercy, often expressing sorrow and humility.
• Gloria: A hymn of praise and thanksgiving.
• Credo: A statement of faith.
• Sanctus: An acclamation of holiness.
• Agnus Dei: A prayer for peace.

The Op. 126 Mass is particularly known for its melodic beauty and its sophisticated harmonic language, reflecting Rheinberger's mastery of counterpoint and orchestration. The work is frequently performed by choirs around the world and remains a staple in the repertoire of late Romantic choral music. It is often used in liturgical settings as well as concert performances.
