This study score of Â"La clemenza di TitoÂ" is based on both Franz GieglingÂ's edition from 1970, which was published as part of the Â"New Mozart EditionÂ", and the critical commentary from 1994. The autograph manuscripts of numbers 2, 11 and 12 of MozartÂ's opera were considered lost after the end of World War II. In 1979/80 these manuscript parts were made available again and are kept in the Biblioteka Jagiellonska, Kraków. The evaluation of this source was published in the critical commentary from 1994 and was included in the second printing of the respective New Mozart Edition volume (1997). The Bärenreiter study score is based on this revised edition of Â"La clemenza di TitoÂ" as published in the Â"New Mozart EditionÂ".
