Fire and Colour: Modern chorale harmonisation and free improvisation for organ (Instrumental Solo)

A comprehensive modern organ method

Fire and Colour: Modern Chorale Harmonisation and Free Improvisation for Organ presents Iris Rieg’s complete two-volume exploration of creative approaches to organ playing. Designed for both study and performance, it integrates harmonic theory, improvisational freedom, and historical awareness across styles from the Renaissance to the modern era.

Volume I – Harmonic exploration and technique

The first volume introduces a systematic approach to building harmonic vocabulary through exercises in parallel shifting structures such as intervals and chords. The harmonisation of scales leads to innovative chord progressions, including those based on thirds and tritones. Ostinato models form the basis for virtuosic toccata-style improvisations, encouraging both creativity and control.

Volume II – Stylistic imitation and historical models

The second volume traces key developments in organ music history and demonstrates improvisational techniques typical of each era. It includes detailed discussions of multi-movement forms such as the concerto, mass, and suite, along with stylistic guidance for Romantic and French tonal idioms inspired by Reger and Dupré. Practical examples help the performer develop an authentic stylistic voice within diverse musical traditions.

For self-study and advanced performance

Intended for students, teachers, and professional organists alike, the method encourages a playful and exploratory approach to improvisation. The material can be entered at any chapter, making it flexible for both structured study and spontaneous inspiration. Featuring bilingual text (German/English) and a clean modern layout with numerous musical examples, *Fire and Colour* is an indispensable companion for anyone seeking to expand their improvisational mastery at the organ.
