Baritone Bas Cornelissen began singing in the Dutch National Children’s Choir but first embarked on a mathematical adventure. During his PhD in computational musicology, Bas fully embraced music and he is now completing a master’s in early music singing at the Conservatory of Amsterdam with Xenia Meijer and Sinan Vural. He studies privately with Andreas Wolf and has taken masterclasses with Margreet Honig, among others.
Bas regularly performs as a soloist in works such as J.S. Bach’s Johannes and Matthäus Passions, Buxtehude’s Membra Jesu Nostri, Charpentier’s Te Deum, Mozart’s Requiem, and Vaughan Williams’ Dona Nobis Pacem. Mahler’s Das Klagende Lied is on the programme for his solo debut at the Concertgebouw in fall 2024.
In addition to his solo work, Bas has extensive experience as an ensemble singer, performing with groups such as the Reisopera. In 2023, he co-organized the Dutch première of Maximilian Steinberg’s choral concerto Passion Week. Currently, he is planning new musical adventures with the newly founded early music ensemble Tempera Mente.

Tempera Mente sings music that tempers the mind and stirs the spirit. After singing together with leading early music groups, six musicians from across Europe formed Tempera Mente in 2024 to find their own path through past musical worlds.
Their debut programme, Seeds of Sorrow, explores music written amidst the ruins of the Thirty Years’ War, a period of profound social upheaval. Praised for its “outstanding mastery” in the interpretation of this repertoire (Südkurier), the ensemble strikes a fine balance between individual expression and a harmonious blend. Each voice enjoys rhetorical freedom to speak directly to the audience—to move, to persuade, and to stir.
Central to Tempera Mente’s approach is a curiosity about the music itself, its performance, its historical context, and how all of this resonates today. Tempera Mente has appeared at festivals such as the Early Music Festival in Utrecht and is thrilled to be part of Sustainable-EEEmerging (2026-27), a European initiative supporting young early music ensembles.
