I've noticed that you don't have "Harold in Italy" by Hector Berlioz. Could you please add this to your Library. I would like to add this to my library also. This piece also ranks up there with Mozart's Symphonie Concertante K364 for Violin & Viola.
The orchestra is composed of strings, with violas divided playing two separate parts, two clarinet sand two horns. The concerto has a rather warmer sonority, maybe with the intent of matching the soloist’s timbre. Sometimes in the second movement the soloist is accompanied only by the two violas.
The work is sometimes arranged and performed as a concerto for violin and viola. A new Urtext edition of the concerto is available from Edition Peters.The viola concerto is a concerto contrasting a viola with another body of musical instruments, usually an orchestra or chamber music ensemble.Early examples of the viola concerto include, among others.
