Olive Music‘s Modena Codex Edition is the first complete edition of this famous manuscript ever to be published. For the first time, all 104 compositions and ten related works have been brought together in a single volume by the authors Kees Boeke and Jos Haring. Every work has been transcribed in an innovative way and is individually accompanied by a descriptive analysis. All information from the manuscript, however insignificant it may appear, has been incorporated into our new transcriptions in order to facilitate research and to assist performers in their performance decisions. Suggestions for the use of instruments are given for each piece individually. An Introduction discusses the musical styles, the composers, instrumentation and is followed by a clear explanation of the editorial conventions used in this special book, that helps to bring the Ars Subtilior style to life for musicians, scholars and amateurs alike.
