Franz Josef Stoiber, organ professor and organist at Regensburg Cathedral, has decided not to present a conventional improvisation tutor here. Instead, he offers a multi-faceted reader and workbook containing useful methodical and pedagogical reflections, e.g. on cultivating a feeling for sound and training responsiveness. It also features a wide range of practical exercises for improvising in various styles, all reflecting his years of experience as a teacher and performer. This guide to organ improvisation has the potential of becoming a standard work in the training of today’s organists.
