As a player of chamber music Ewald Demeyere has worked with, among others, Barthold, Sigiswald and Wieland Kuijken, and with Paul Dombrecht. For many years he has been a member of La Petite Bande (Sigiswald Kuijken) and was also part of the discontinued ensemble Il Fondamento (Paul Dombrecht). In July 2004 he was Guest of Honour at the Festival of Flanders Musica Antiqua in Bruges.
Ewald Demeyere has taken part in many recordings for radio and television. Among his CD recordings are Eight Keyboard Sonatas by Thomas Augustine Arne, Sonatas & Fugues by Wilhelm Friedemann Bach, the sonatas for flute and harpsichord by Johann Sebastian Bach (with Barthold Kuijken), the complete sonatas for flute and basso continuo by Carl Philipp Emanuel Bach (with Barthold Kuijken), Pièces de Clavecin by Joseph-Hector Fiocco and Sonatas by Domenico Scarlatti.
In 2007 he founded the Baroque orchestra Bach Concentus, which has already appeared in Belgium, Italy and Spain. Bach Concentus realized recordings of overtures by Johann Bernhard Bach and Georg Philipp Telemann, vocal and orchestral works by Telemann inspired by the commedia dell’arte and symphonies of the sons of Johann Sebastian Bach.
Apart from his work as a harpsichordist and conductor, Ewald Demeyere is active in the field of musical theory. He is principally interested in the influence of the theories from the Baroque era on instrumental practice, and in particular on the interpretation of the music of Johann Sebastian Bach.
In 2009 he obtained a PhD at the University of Antwerp and the Artesis Hogeschool Antwerpen (Associatiefaculteit Kunsten), when he presented his thesis A Contextual, Text-Critical Analysis of Johann Sebastian Bach’s Art of Fugue – Reflections on Performance Practice and Text-Critical Analysis, and the interaction between them.
His book Johann Sebastian Bach’s Art of Fugue – Performance Practice based on German Eighteenth-Century Theory was published by Leuven University Press in 2013.
