Felix Mahr was born in Ulm, Germany and raised in a small community near Berlin. At the age of 12, he attended the Musikgymnasium Schloss Belvedere in Weimar, where he studied recorder and piano. In 2011, he graduated and began studying in the same year BA1 Studienrat (teacher accreditation) at the Universität der Künste. Later, he also studied recorder (focus: early music) and achieved in both studies a bachelor degree (Bachelor of Arts and Education / Bachelor of Arts). Currently Felix Mahr is studying recorder and music theory to get a Master degree in both subjects.
His approach to music theory is very practical and focused on the compositions itself rather than a theoretical concept. Thus, an important field is composing in different historical styles and a form of analysis that treats practical compositional problems. A major focus is early baroque improvisation, which he learns in an autodidactic way and already teaches in private lessons. In 2017 and 2018, he improvised on the harpsichord in university concerts. As a member and tutor of the Kontrapunkt-Chor Berlin, Felix Mahr is also trained in vocal renaissance improvisation techniques. The recorder plays an important role in his personal relationship to music and recently, he participated in the performance of the French Baroque Opera David et Jonathas by Charpentier (2018, St. Elisabeth Kirche, Berlin-Mitte) as a recorder player in the orchestra.
