Clara Schumann's cadenzas to piano concertos by Beethoven (Opp. 37 and 58) and Mozart (K466) not only give a unique insight into her performing and composing style; they also throw light on her relationship with Johannes Brahms, whose cadenzas have considerable similarities to those of Schumann. This Urtext edition of the cadenzas includes a preface in which the renowned Canadian pianist Ludwig Sémerjian explores the interaction between Schumann and Brahms. The edition also marks the first publication of Clara Schumann's early cadenzas for Mozart's D minor Piano Concerto, previously only available in the manuscript in the Library of Congress in Washington DC.
