A Sacred Work Rediscovered
Charles Tournemire’s L’Orgue Mystique is one of the most ambitious sacred music projects ever composed: Fifty-one suites, one for nearly every Sunday of the liturgical year, rooted in Gregorian chant and meant to sanctify time through sound.
This book brings that visionary work back to life, contextualizes it, and makes it relevant to a new audience.
“Charles Tournemire’s L’Orgue Mystique: La Haute Mission” is the first comprehensive English-language exploration of this musical masterpiece. Part history, part theology, part performance guide, it is the culmination of a fifteen-year journey through study, performance, and prayer, combining performance insight, liturgical context, and cultural depth.
This is a book that makes an important work of organ music accessible, and invites the reader into a dialogue with tradition, mystery, and transcendence — whether you approach it from the console, the lectern, or the pew.
This magnificent book is not to be absorbed in a single sitting. It is a book to be read and re-read… gradually integrated into one’s understanding of the historical, political, aesthetic, and intellectual currents of the period.”
— William Renwick, McMaster University

The Structure of the Book
This richly structured book unfolds in three major parts, each offering something unique:
Part I — Spiritual & Cultural Foundations
A deep exploration of Tournemire’s influences: chant revival at Solesmes, the writings of Dom Guéranger, Symbolist aesthetics, and the mystical ambitions of post-Revolution Catholic France. Over 200 pages of cultural, spiritual, and political background spanning the French Revolution through the early 20th century.
Part II — Performance & Interpretation
Detailed insight into the structure of L’Orgue Mystique, with guidance on performing, adapting, and breathing life into the cycle — whether on grand cathedral instruments or modest parish organs. Spotts explores the liturgical architecture of the 51 Offices and their roots in the Messe basse tradition. Offers guidance on registration, rubato, rhythmic flexibility, and interpretive freedom — even for smaller organs.
Part III — Liturgical Texts & Chant Connections
Includes full chant incipits, scripture texts, and commentary aligned with each suite, helping readers uncover the rich interplay between liturgy and melody. Presents the chants, antiphons, and liturgical readings for each suite — with commentary that helps connect Gregorian themes to musical expression and theological symbolism. Based on Dom Guéranger’s L’Année liturgique.
“As someone who has performed L’Orgue Mystique extensively, Spotts is in a unique position to enlighten his readers concerning performance and interpretation.”
— William Renwick
Spotts encourages the performer to move beyond the notation — toward something more expressive, more fluid — closer to chant and improvisation.”
— Ann Labounsky
Why This Book Matters Now
This isn’t a mere reference text — it’s a call to rediscover sacred time, through music that was meant to lift the soul, not just accompany a rite.
Tournemire’s music is radical, reverent, and still radiantly alive. Spotts gives readers the tools to hear it, understand it, and bring it to others — in worship, on the concert stage, or in quiet reflection.
A thorough, detailed, and sensitive account… essential reading for all those interested in French organ music and the role of music in the Catholic liturgy.”
— Kevin Faulkner
Spotts writes with passion and humility, always allowing the subject to lead.”
— Harold Stover
This book will be of great value to organists who wish to better understand the nature of this vast musical and liturgical cycle.”
— Ann Labounsky
