Mandolin 1796: Sonatine WoO 43a; Adagio ma non troppo WoO 43b; Sonatine WoO 44a and Andante con Variazioni WoO 44b. The opera "Don Giovanni" by Mozart (1787) includes mandolin parts, including the accompaniment to the famous aria "Deh vieni alla finestra", and Verdi's opera Otello calls for guzla accompaniment in the aria "Dove guardi splendono raggi", but the part is commonly performed on mandolin. Gustav Mahler used the mandolin in his Symphony No. 7, Symphony No. 8 and Das Lied von der Erde. Parts for mandolin are included in works by Schoenberg (Variations op. 31), Stravinsky (Agon), Prokofiev (Romeo and Juliet)
Mandolin instruments. The mandolin and guitar were played in both classical music and pop music. Although used in popular music, both instruments were also taught in the Saigon National Conservatory (now the Conservatory of Ho Chi Minh City). However, the mandolin has disappeared from the conservatory where it had been taught, apparently dropped from the curriculum. Instead of Guitar-Mandolin department, the school lists Guitar-Accordion. Though probably never a dominant instrument, the mandolin was learned by enough people to have a presence among the settlers who left Vietnam for the United States, and who continued to play mandolins in their new home.
