The results presented in this dissertation, written by Kathryn Cok, demonstrate the generous contribution that the Dutch Republic has made to the genre of basso continuo, including a survey of twenty-six Dutch sources from the 17th and 18th centuries. Focus has been made on the written record of the practice in the Dutch Republic of the time, including method books, music books where mention is made of basso continuo, dictionaries with detailed descriptions of the practice, and translated foreign treatises, all helping to paint a picture of how the practice was put into effect. Special attention has been given to a relatively unknown manuscript by Jan Alensoon.
