The Registration of Baroque Organ Music is the first book-length study of the registrational practices of organists from c. 1550 to 1800. Each of the four parts of the book-the Renaissance and the Early, High, and Late Baroque-starts with a brief description of the political and religious climate of the period and the way such factors affected the compositions and the organ-building of the time.Within each historical period, Owen provides for each country a list of the active composers and information about representative organs, including their locations, dates, and builders, along with stoplists. She then discusses the registrational practices in each area in relation to contemporary musical styles and forms, referring to sources such as scores and treatises.
