Denis Lossev is a pianist and assistant professor in the Piano Chair alongside Milana Chernyavska at the Reina Sofía School of Music in Madrid. He previously worked with Dmitri Bashkirov (2010–2021) and was a piano accompanist in Zakhar Bron’s Violin Chair (2006–2010).

Born in Saint Petersburg, he trained at the Special School for Gifted Children and the Rimsky-Korsakov Conservatory. In 1997, he moved to Madrid on a full scholarship to study with Dmitri Bashkirov at the Reina Sofía School of Music. He later earned advanced diplomas in Piano and Concert Performance from the École Normale de Musique de Paris.

He made his solo debut at 19 at the Grand Hall of the Saint Petersburg Philharmonia, receiving critical and public acclaim. He was the first pianist to perform Britten’s Piano Concerto in that venue after Sviatoslav Richter.

He has performed in festivals and venues including the Ruhr Piano Festival, Madrid’s Auditorio Nacional, and the Moscow Conservatory, and has taken masterclasses with Maria João Pires, Alexis Weissenberg, and Michel Béroff.
