The Dutch pianist, organist, improviser and music theorist Bert Mooiman studied at the Royal Conservatoire in The Hague, The Netherlands, where he took his certificates as a solo pianist and organist cum laude. In 2003 he finished his Music Theory studies with a prize winning paper on the relation between the work of Olivier Messiaen and French Romantic tonal harmony. Since then he has taught music theory as a principal subject, improvisation and piano at the Royal Conservatoire, where he also works as a research supervisor. He performs both on piano (solo, chamber music) and on organ (solo, basso continuo). His work as a researcher and his activities as a performer meet in his lifelong interest in improvisation as a basis for true interpretation, which also became the topic of his current PhD research at Leiden University
