The circulation of music in the Iberian World was influenced by a number of diverse factors during the sixteenth and early seventeenth centuries including the commercial routes established for the general international book trade, the specific dynamic between printers active in Spain, Portugal and the New World and the mainly local or regional markets for the works they printed, and the impact of major historical developments such as the Council of Trent. Early Music Printing and Publishing in the Iberian World is a volume of essays by leading book and music historians that draws on a wide range of methodologies to address questions of distribution, accessibility and demand for vocal and instrumental repertories, the acquisition and use of books of chant and polyphony by ecclesiastical institutions, and to analyse the networks by which printed music circulated and the implications of printing for musical practice. This book marks the first step towards a greater understanding of how the advent of music printing at the beginning of the sixteenth century affected musical culture and development not only in the Iberian Peninsula but also in the New World.
