Stephanie McCallum (born Sydney, Australia, 3 March 1956) is a classical pianist. She has recorded works of Erik Satie, Ludwig van Beethoven, Charles-Valentin Alkan, Franz Liszt, Robert Schumann, Carl Maria von Weber, Albéric Magnard, Pierre Boulez, and Iannis Xenakis among others. 　　Stephanie McCallum has released 18 solo CDs, and her recordings of the music of Liszt and her popular CDs of French piano music have recently been re-released as boxed sets. Her recording of all of Beethoven's Bagatelles for piano, contains the published sets of Bagatelles, Opus 33, 119 and 126, individual pieces such as the popular Für Elise, and also the first recording of what is believed to be the last piano piece that Beethoven wrote, never before published or even catalogued (the piece was edited by Stephanie's husband, the musicologist Peter McCallum).[1][2] She has made a particular specialty of virtuosic nineteenth century music, making a specialty of Alkan, and of contemporary solo and ensemble music. She made the first recording of Alkan's Studies in all the Major Keys, Opus 35, and subsequently recorded Alkan's Studies in all the Minor Keys, Opus 39, being the first pianist to record both sets. In 2013, during the centenary of Alkan's birth, she released recordings of all five Books of Alkan's Chants, along with other previously unrecorded music by this composer. Her performances of Xenakis's Herma, and Brian Ferneyhough's Lemma Icon Epigram have received critical acclaim. She has released CDs of the music of Liszt, Weber, Alkan, Schumann, Magnard, Pierre Boulez, Xenakis and of contemporary Australian composers. Stephanie McCallum is the only pianist to have recorded both the major and the minor key studies (Opus 35 and 39) of Alkan. In addition to Alkan and Pierre Boulez, she has recorded much other music by French composers: Erik Satie, Albéric Magnard, Vincent d'Indy, Maurice Ravel and Guy Ropartz.
