This concerto by Franz Danzi is in the classical style.  It consists of three movements; the first comprising the majority of the work.  The first movement, written in sonata form, is quite challenging in terms of range, endurance, and style.  The second movement is lyrical and the final movement is a lively rondo.  This piece, while frequently overlooked, is an admirable alternative to both the Mozart concerti and the Beethoven sonata.  In terms of technique and musicality, this piece requires strength, flexibility, and elegance for proper execution.
