La Gioconda and Louise are both types of which musical style?
La Gioconda (opera) La Gioconda is an opera in four acts by Amilcare Ponchielli set to an Italian libretto by Arrigo Boito (as Tobia Gorrio), based on "Angelo, Tyrant of Padua", a play in prose by Victor Hugo, dating from 1835. (This is the same source as Gaetano Rossi had used for his libretto for Mercadante's "Il giuramento" in 1837).
Goadec Sisters The Goadec Sisters (Ar C'hoarezed Goadeg in Breton) usually known as "Les sœurs Goadec" in French, was a Breton singer group originating from Treffrin (Côtes d'Armor, France). The trio represent the traditional music of Brittany, singing a cappella. The three sisters were Maryvonne (1900-1983), Eugenie (1909-2003) and Anastasie Goadec (1913-1998). They began to animate "fest-noz" (night festival) in 1956, among the pipers and bombard players. Accompanied until 1964 by their two sisters, Louise (1903-1964) and Ernestine (1911-1964), their repertoire consists mainly of laments ("Gwerzioù" in Breton). As a trio, they attempted to integrate the song to dance and adapted the technique of repetition ("kan ha diskan").
