context: Title: CastaDiva

  Title: La somnambule, ou L'arrivée d'un nouveau seigneur
  Passage: La somnambule is a ballet-pantomime composed by Ferdinand Hérold and premiered on 19 September 1827 at the Académie Royale de Musique.  The scenario was by Eugène Scribe, and it was choreographed by Jean-Pierre Aumer.  This ballet was produced in 1827 at the height of a fashion for stage works incorporating somnambulism.  The work was quite popular in Paris and inspired many more works incorporating somnambulism, including Vincenzo Bellini's well-known Italian opera "La sonnambula".
  Title: Antonino Votto
  Passage: Antonino Votto (30 October 1896 - 9 September 1985) was an Italian operatic conductor.  Votto developed an extensive discography with the Teatro alla Scala in Milan during the 1950s, when EMI produced the bulk of its studio recordings featuring Maria Callas.  Though Votto was a dependable conductor (and the teacher of Riccardo Muti), critics frequently faulted his recordings for their lack of emotional immediacy.  This may have been an occupational hazard of working in the studio, as his live sets with Callas, including a "Norma" (December 1955, La Scala) and "La sonnambula" (1957, Cologne) are considered to be great performances.

  Title: Monumentum pro Gesualdo

It was first performed in conjunction with "Movements for Piano and Orchestra" in 1965, and this practice has been followed almost consistently since 1966, with the same leading female dancer in both in most performances.  The ballet has three parts, each of just over two minutes duration.  NYCB principal dancer Darci Kistler chose to include "Monumentum pro Gesualdo" in her farewell performance, Sunday, June 27.

  Title: Tenore di grazia
  Passage: Tenore di grazia , also called leggero tenor ("graceful" and "light" tenor, respectively), is a lightweight, flexible tenor voice type.  The tenor roles written in the early 19th-century Italian operas are invariably leggero tenor roles, especially those by Rossini such as Lindoro in "L'italiana in Algeri", Don Ramiro in "La Cenerentola", and Almaviva in "Il barbiere di Siviglia"; and those by Bellini such as Gualtiero in "Il pirata", Elvino in "La sonnambula" and Arturo in "I puritani".  Many Donizetti roles, such as Nemorino in "L'elisir d'amore" and Ernesto in "Don Pasquale", Tonio in "La fille du régiment", are also "tenore di grazia" roles.  One of the most famous leggero tenors of that period was Giovanni Battista Rubini, for whom Bellini wrote nearly all his operas.
