A very nice example and explanation of music printing.
This is a small video that, in a very clear and resumed way, shows how music books were printed in the sixteenth century and afterwards. It features the process using movable pieces of type, very similar to that of traditional printing of the time. Most of the video takes place in the Plantin workshop in Antwerp, one of the most important music printing houses of Europe during the sixteenth century and where Portuguese composer Duarte Lobo printed four polyphony books in 1602, 1607, 1621 and 1639 respectively. The video is provided by The Open University.
