Arabella

Arabella, Op. 79, is a lyric comedy or opera in three acts by Richard Strauss to a German libretto by Hugo von Hofmannsthal, their sixth and last operatic collaboration.
Arabella is determined to marry for love, not wealth - against the wishes of her impoverished aristocratic parents. When she gives her heart to the mysterious Mandryka, a series of misunderstandings puts their love to the test.
