During recent years the solo concert repertory for viola has been extended by several works. One example is the Viola Concerto in C, the reconstruction of a harpsichord concerto by Johann Sebastian Bach. Other compositions, such as those by Ignace Joseph Pleyel or Antonio Rosetti, have been published for the first time. They are all welcome additions to this classical genre, one of whose most ingenious works is surely Wolfgang Amadeus Mozart's Sinfonia Concertante in E flat major. Two further classical works are the Concertos in D major by Carl Stamitz (Op. 1) and Franz Anton Hoffmeister (1754-1812). The latter was known and respected in his time not only as a composer, but also as a publisher. Both works are the most common audition pieces for viola players to this day.
