Mercedes Capsir (Catalan pronunciation: [mərˈsɛðəs kəpˈsi]) (20 July 1895 - 13 March 1969) was a Catalan Spanish opera singer, a high coloratura soprano, particularly associated with light Italian roles, such as Lucia and Gilda.
Mercedes Capsir was born in Barcelona, Spain, in the same house where another Spanish soprano had been born 12 years earlier, Maria Barrientos. She studied (piano, composition, voice) at the Music Conservatory in Barcelona, before making her debut in Genora, in 1913, as Gilda in Rigoletto, a role she will remain closely associated with throughout her career.
In 1916, she made her debut at the Liceo in Barcelona, the Teatro Real in Madrid, the "Teatro Nacional São Carlos" in Lisbon, the Teatro Colón in Buenos Aires, as well as at the Paris Opéra in 1917. Gilda was her debut role at all these opera houses.
Her Italian debut took place in Bologna, as Rosina in Il barbiere di Siviglia, followed by Elvira in I puritani, in Venice, opposite Giacomo Lauri-Volpi, she also appeared in Rome, before reaching La Scala in Milan, in 1924, again as Gilda, opposite baritone Carlo Galeffi and tenor Miguel Fleta, and conducted by Arturo Toscanini.
Capsir sang mainly in Europe, and in a very limited repertory, other roles included: Amina in La Sonnambula, Lucia in Lucia di Lammermoor, and Violetta in La traviata. She took part in performances of Giordano's Il Re at La Scala in 1929.
