Impossible for me to select one, but some of my favorites are: Machaut: Notre Dame Mass Ockeghem: Missa Mi-mi Byrd: Mass for Three Voices Monteverdi: L’Orfeo, Beatus vir J.S. Bach: Art of the Fugue, Brandenburg Concertos Haydn: Symphonies 22,46,60,63,77; Cello Concertos in C and D Beethoven: Symphonies; Piano Concertos #4 and #5; late string quartets, Violin Concerto Schubert: Symphonies #5 and #9, String Quintet in C; Rosemunde Mendelssohn: Octet for Strings, incidental music for Midsummer's Night Dream Dvorak: Slavonic Dances, Opp. 46 and 72; Legends, Op.59; Serenade for Strings Vaughan Williams: Lark Ascending, Tallis Variations, Five Variations on Dives and Lazarus Copland: Quiet City, Our Town Also in regard to the "what do you mean by classical" discussion happening here... No offense, but this is not accurate. As we know, the term "classical" has numerous meanings. The correct musicological term for what the general public calls classical music is Western art music with classical being the period of Western art music from 1750 to 1825...the 6 main periods of Western art music: Medieval: c. 500 A.D. to 1450 Renaissance: 1450 to 1600 Baroque: 1600 to 1750 Classical: 1750 to 1825 Romantic: 1825 to 1900 Modern: 1900 to present (there are other terms which have been used for this period...this is a really general way to refer to this...and there are numerous styles within this period) Also, Western art music is not limited to music written for orchestra. Best to all, Ken
