Rieg, Iris: Fire and Colour

Moder Organ Improvisation

In her two-volume organ improvisation method, Iris Rieg presents an immense wealth of creative yet systematic approaches for discovering colourful harmonies on the “queen of instruments.” She clearly demonstrates how one can experiment and play with intervals, chords, scales, rhythm patterns and much more, in styles ranging from the Renaissance to the modern era. In the first volume, the author provides an introduction to various harmonic techniques, starting with systematic exercises based on parallel shifting musical structures (intervals, chords). The harmonisation of scales leads to interesting chord combinations, including those based on thirds and tritones. Using ostinato models, instructions are given for the conception of a virtuoso toccata. Significant milestones in the history of organ music form the guiding principle for the second volume. Here organists becomes acquainted with characteristic improvisation techniques. Valuable tips for creating stylistic imitations enrich the detailed descriptions of multi-movement forms, such as concerto, mass or suite. Particular emphasis is based on romantic harmonisation (Max Reger) and French tonal aesthetics (Marcel Dupré). The two volumes, which are ideal for self-study for students, teachers and professional organists, are aimed at those who want to start improvising in church services, but also offer inspiration to those who already improvise on a daily basis and, for example, want to create an organ symphony based on hymns in a live setting. The numerous exercises at different levels of difficulty are logically structured yet allow organists to start at any chapter and begin right away. Above all, the joy of playing always takes centre stage!
