Orchestral Music

Among a variety of orchestral works, including a piano concerto and a violin concerto, Reger's Variations and Fugue on a Theme of Mozart, an arrangement of his work of the same title for two pianos, is typical of his resourceful and sometimes complex use of the theme on which it is based.

Chamber Music

Reger wrote a considerable amount of chamber music of all kinds, with a number of violin sonatas and other duo sonatas, as well as string quartets and works for other groups of players. While of interest, nothing of this has become a part of popular repertoire, either for players or audiences.

Vocal and Choral Music

Among choral compositions by Reger the eight Geistliche Gesänge (Spiritual Songs), Op. 138, have proved particularly moving. Once again his choral works and songs have failed to achieve any significant position in performing repertoire.

Piano Music

Reger wrote a number of short piano pieces. His Variations and Fugue on a Theme of Mozart, Op. 132a, for two pianos, is probably the best known of his compositions for piano. Other sets of variations include Variations and Fugue on a Theme of Beethoven, Op. 86,for two pianos, Variations and Fugue on a Theme of J.S. Bach, Op. 81 and Variations and Fugue on a Theme of Telemann, Op. 134, for one piano.

Organ Music

Reger's organ music offers a considerable challenge to performers and some works are said to have been composed as just such a challenge to his friend, the organist Karl Straube. Notable organ works include Chorale Fantasias on Ein' feste Burg ist unser Gott, Op. 27, and other Lutheran chorale tunes. His compositions for organ include a Fantasia and Fugue on the name of Bach.
