Petros Bakalakos was born in Thessaloniki, Greece. There he completed his piano studies with distinction. He then studied piano and organ at the Royal Academy of Music in London and at the Stuttgarter Musikhochschule as a scholarship holder of the Nicholas Danby Trust. He also studied harpsichord and song composition and worked as a teacher of accompaniment. His love for singing led him to work as a répétiteur at the International Opera Studio in Zurich and at the operas in Antwerp and Ghent. In 2009 he was a finalist in the song competition 'Schubert and the Music of Modernity' in Graz. As a répétiteur and musical assistant he has worked with conductors such as René Jacobs, Teodor Currentzis, Philippe Jordan, Alberto Zedda and Riccardo Chailly for opera productions at the Opernhaus Zürich, the Ruhrtriennale, the Theater an der Wien, the Dutch National Opera in Amsterdam and the Salzburger Festspiele, among others. As a conductor, he has conducted Offenbach's 'La Vie Parisienne' and Bizet's 'Don Procopio' for the Zurich Chamber Orchestra's Operabox, as well as Purcell's 'Dido and Aeneas' at the Teatro Arriaga in Bilbao. Since 2021 he has been teaching the subject of accompaniment and role studies as an academic assistant at the Hochschule für Musik Freiburg i. Breisgau.
