José Carlos de Sequeira Costa (born 18 July 1929 in Luanda, Angola) is a Portuguese pianist who is especially renowned for his interpretations of the Romantic repertoire.
As a child, Sequeira Costa showed exceptional musical talent. When he was eight years old, he moved to Lisbon to become the protégé of José Vianna da Motta who was one of the last pupils of Franz Liszt. Following Vianna da Motta's death in 1948, Sequeira Costa continued his studies in London under another eminent pianist, Mark Hambourg. Sequeira Costa also worked with Marguerite Long and Jacques Fevrier in Paris and Edwin Fischer in Switzerland. Under these teachers, Sequeira Costa was immersed in both the German and French schools of pianism. In his performing career, Sequeira Costa has drawn upon his understanding of both traditions to develop his personal style of musical interpretation.
At the age of 22, Sequeira Costa won the Grand Prix at the Marguerite Long International Piano Competition. Five years later, he founded the Vianna da Motta International Music Competition in Lisbon. In 1958, Dmitri Shostakovich invited Sequeira Costa to sit on the jury of the inaugural International Tchaikovsky Competition in Moscow, on which he served a further six times.
Today, Sequeira Costa continues to appear regularly on the panels of some of the world's most prestigious music competitions, while also delivering numerous master classes and giving regular tours. Sequeira Costa has recorded the complete cycle of piano concertos by Sergei Rachmaninoff, and has recently completed his final recording of the complete sonatas of Beethoven.
