Hanna-Elisabeth Müller is a prominent soprano, active in opera, song repertory, and concert music. She has a large repertory stretching from Mozart to the contemporary era.

Müller was born in Mannheim, Germany, on May 3, 1985. She started her musical life on the violin but switched to voice after joining a choir. Beginning at age 11, she took voice lessons from Judith Jantzen, and three years later, she took the boy soprano part in a performance of Leonard Bernstein's Mass at the Kultursommer Ludwigshafen festival. She continued to sing through secondary school, and after winning several prizes in youth Jugend musiziert competitions, she enrolled at the Hochschule für Musik und Darstellende Kunst Mannheim. She went on to take master classes from such famed singers as Dietrich Fischer-Dieskau, Júlia Várady, Elly Ameling, and Thomas Hampson. Müller racked up several more prizes, including Ton und Erklärung-Werkvermittlung in Musik und Wort of the Kulturkreis der Deutschen Wirtschaft (which required her not only to sing music but also explain it), and then joined the opera studio of the Bavarian State Opera for the 2010-2011 season. She was added to the company itself in 2012 and remained there until 2016, also appearing at a variety of other houses. In 2013, she was featured on tenor Rolando Villazón's Stars de Demain ("Stars of Tomorrow") series. She made her recording debut in 2017 on a recording of Mahler's Symphony No. 4 in G major with the Düsseldorfer Symphoniker under conductor Ádám Fischer. That year, she was also a last-minute replacement in Beethoven's Symphony No. 9 in D minor, Op. 125, at the Elbphilharmonie in Hamburg.

Another milestone in 2017 was Müller's debut at the Metropolitan Opera in New York as Marzelline in Beethoven's Fidelio. Since then, she has appeared at other major houses, including Italy's La Scala, as Donna Anna in Mozart's Don Giovanni. Müller is also an enthusiastic song recitalist whose concerts have often been broadcast on Germany's Südwestrundfunk radio network. In 2019, she was signed to the PentaTone Classics label, where she released the song recital Reine de coeur, accompanied by Juliane Ruf, the following year. She returned in 2022 with the orchestral song album Sinnbild: Strauss Songs, joined by the WDR Symphony Orchestra under Christoph Eschenbach. ~ James Manheim, Rovi
