This is the first monographic work to be published on one of the most important musical centres and chapels in the Valencian Community: the cathedral of Segorbe, which until now had not been researched. Thanks to the work carried out in the archives of the cathedral on the chapter minutes, factory books and other unpublished documentation, it has been possible to bring to light for the first time numerous data and conclusions that show the extraordinary importance that the music chapel of Segorbe reached throughout the 18th century
