_C !1Susanna: A Program Note!2 _S200 This newly edited version of Handel's oratorio !4Susanna!2 has been produced electronically, utilizing facilities developed by Walter B.

Handel's music has been fed into a computer system, part by part, from his autograph and other early sources. The text, which is anonymous, has been adapted from a recently discovered copy of the 1749 libretto at the University of Texas, Austin. After extensive proofreading and proofhearing, final copy was approved by the conductor, Nicholas McGegan, for the creation of the performing score and parts. This version of the work, in which material not available in other modern editions has been added in Nos. 14, 22, 68, and 71, remains on-line and will become part of the Center's !4Handel Database!2. _NP In relation to the autograph, which was revised for subsequent performances, this version of the work reflects the following changes: _M+50 _L-100 1. !4Components!2.

Like a few text revisions in a lighter ink, they may in fact derive from a performance given in 1759, a few weeks before the death of the composer, who was then blind. 3. !4Orchestration!2. Handel's violins are generally divided into two sections. In No. 71 a third section is added. Trumpets also appear in the last large numbers of the work. Handel does not call for timpani in this work, although at this date it timpani were frequently used in conjunction with trumpets. The rare independent lines for bassoon, which generally follows the continuo line, serve
