Raphael Höhn began his singing career with the Boys Choir of Zurich. His success as an alto soloist led to the recording of several CDs. As a young tenor he started his pre-studies in voice performance at the Konservatorium Zürich under Frédéric Gindraux. After completing his Master in Music Pedagogy at the Zürcher Hochschule der Künste with Scot Weir, he decided to devote his studies to early music and completed a Masters in Early Music Voice in the Royal Conservatory of the Hague where he studied under Rita Dams, Peter Kooij, Michael Chance and Jill Feldman. He attended masterclasses with Andreas Scholl, Gerd Türk, Jean-Paul Fouchécourt and Mariëtte Witteveen.

As a soloist he gives concerts all over Europe. Within his broad repertoire reaching from the renaissance polyphonic to contemporary music, he is particularly devoted to the interpretation of baroque pieces, placing special emphasis on the rhetorical implementation of the text. He worked with conductors such as Ton Koopman, Frans Bruggen, Jos van Veldhoven, Vacalv Luks and Howard Griffiths and his path led him to the Lucerne Festival, the Händel Festspiele Göttingen, and the Bachfest Leipzig. At the same time, he sings in the professional soloist vocal ensembles Voces Suaves and Vox Luminis.

Raphael Höhn was awarded a grant by the Migros Kulturprozent in 2014 and is prize winner of the International Bach Competition Leipzig (2016).
