Ewald Demeyere studied at the Koninklijk Conservatorium Antwerpen, where, besides winning first prizes in solfège, written and practical harmony, counterpoint and fugue, he obtained his master's degree for harpsichord in Jos van Immerseel's class.
On completion of his studies in 1997, he was engaged as a teacher of harmony, counterpoint and fugue by the Koninklijk Muziekconservatorium Antwerpen. In 2002 he succeeded Jos van Immerseel as Professor of Harpsichord, and teaches harpsichord there on the instruments in the famous collection of the Vleeshuis Museum.
As a player of chamber music he 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 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, for the ACCENT label, 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), Johann Sebastian Bach – The Young Virtuoso, the complete sonatas for flute and basso continuo by Carl Philipp Emanuel Bach (with Barthold Kuijken), Pièces de Clavecin by Joseph-Hector Fiocco, Sonatas by Domenico Scarlatti and Flute Sonatas by the Bach Sons (with Barthold Kuijken).
In 2007 he founded the Baroque orchestra Bach Concentus, which has already appeared in Belgium, Italy and Spain. Bach Concentus realized until now two CD recordings, both for ACCENT. In March 2008 a first double CD appeared with overtures by Johann Bernhard Bach and Georg Philipp Telemann. In January 2010 a new CD by Bach Concentus was released, entitled La Bouffonne, with vocal and orchestral works by Georg Philipp Telemann inspired by the commedia dell’arte (with Dorothee Mields, soprano). In the spring of 2012 a recording will appear, again for ACCENT, with 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.
He has published two articles in the Dutch Journal of Music Theory (Amsterdam University Press): Ebenezer Prout: Bach as a model for the teaching of fugue (2003) en The Art of Fugue: exemplary or experimental? (2005).
In 2007 he wrote the articles La fugue partimento : exercice ou composition ? for the book Les Écritures Musicales (Éditions Mardaga, 2007) and On BWV 1080/8: Between Theory and Practice (Eighteenth-Century Music, 2007).
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.
