Hyden and the symphony T There are 106 symphonies by the classical composer Joseph Haydn. Of these, 104 have numbers associated with them which were originally assigned by Eusebius Mandyczewski in 1908 in the chronological order that was known at the time.[1] In the subsequent decades, numerous inaccuracies in the chronology (especially in the lower numbers) were found, but the Mandyczeski numbers were so widely used that when Anthony van Hoboken compiled his catalogue of Haydn's works, he incorporated the Mandyczeski number into Catalogue I (e.g., Symphony No. 34 is listed as Hob. I/34).[1] Also in that time period, two additional symphonies were discovered (which were assigned non-Mandyczeskian letters A and B) bringing the total to 106. Franz Joseph Haydn[1][2] (March 31, 1732 – May 31, 1809) was an Austrian composer. He was one of the most important, prolific and prominent composers of the classical period. He is often called the "Father of the Symphony" and "Father of the String Quartet" because of his important contributions to these genres. He was also instrumental in the development of the piano trio and in the evolution of sonata form.[3][4] A life-long resident of Austria, Haydn spent much of his career as a court musician for the wealthy Hungarian aristocratic Esterházy family on their remote estate. Isolated from other composers and trends in music until the later part of his long life, he was, as he put it, "forced to become original".[5] At the time of his death, he was one of the most celebrated composers in Europe.[6] Joseph Haydn was the brother of Michael Haydn, himself a highly regarded composer, and Johann Evangelist Haydn, a tenor. He was also a close friend of Wolfgang Amadeus Mozart and a teacher of Ludwig van Beethoven. http://www.youtube.com/view_play_list?p=07639388576F9C81 &playnext=1&playnext_from=PL&v=ILEsEK-JkJI That's all tnx
