Sebastian de Leeuw
bas-bariton - klavecinist dirigent

Sebastian de Leeuw received his first singing lessons from Sara Klein Horsman and Felix Schoonenboom. After a preliminary year of music studies with Harry van Berne, he started a bachelor’s degree at the Utrecht Conservatory with Jón Thorsteinsson, while also taking lessons with Charlotte Margiono and Peter Bording. He then continued his studies at the Royal Conservatory of The Hague to specialise in early music under the expertise of Peter Kooij, Michael Chance, Pascal Bertin and Rita Dams. To dig even deeper into the performance and analysis of French baroque music, he studied in Paris with Iakovos Pappas and Hubert Weller.
Sebastian started his career as a soloist with a series of Bach cantatas in his home town, Zwolle. He then made the step to larger repertoire and sang several roles in oratorios and masses by Bach, such as the Matthäus- and Johannespassion (Westerkerk, Amsterdam) and the Mass in B Minor with the Bach Ensemble Amsterdam. As a choral singer, Sebastian performed Bach motets under the baton of Ton Koopman, and appeared in a staged version of Bach’s Johannespassion by the Nederlandse Reisopera. Past performances in operatic roles include: Chibante in A Vinganca da Cigana (Moreira), Bello in La Fanciulla del West (Puccini), Don Giovanni in Don Giovanni (Mozart) and Osman and Ali in Les Indes Galantes (Rameau).

As a vocal coach and chef de chant, Sebastian has worked with companies like BeVoice Berlin, Utrecht City Opera and Opera Minora. He has his own private lesson practice in the Netherlands.
In the first years of his singing studies, Sebastian was introduced to the harpsichord and quickly picked it up as his main instrument, taught by Siebe Henstra. He has since become a skilled continuo player and is a regular guest of ensembles like ’t Kabinet and the Kammerphilharmonie Emsland. As a soloist, he gave recitals throughout the Netherlands, as well as in Berlin, Paris, Rome and Izmir. He played on authentic period instruments at the Vleeshuys in Antwerp and in San Colombano in Bologna. Sebastian was chosen as a participant in the Académie Versailles 2018, organised by the Centre de Musique Baroque de Versailles (CMBV).

During his studies, Sebastian took conducting lessons in Utrecht and Paris. He is the founder and artistic leader of Le Concert du Trianon, an orchestra focusing on theatrical performance of French baroque music. Since 2016, he is conductor in residence and artistic advisor at Leeuwenbergh, Utrecht, as well as production manager at the festival Itinéraire Baroque in the French Dordogne, of which Ton Koopman is the artistic director.
