ISBN 9780757999741. One of the leading composers of instrumental music of the early Romantic period, Louis Spohr was a violinist, composer, and conductor. In addition to symphonic works, string quartets, and other solo and chamber music, he composed operas, operettas, and songs. Of the fifteen violin concerti he composed, his Violin Concerto no. 7 in c minor was written in 1814. There has been a trend, starting in the late 20th century, to revive his instrumental works and songs.
