The lute's strings are arranged in courses, of two strings each, though the highest-pitched course usually consists of only a single string, called the chanterelle. In later Baroque lutes two upper courses are single. The courses are numbered sequentially, counting from the highest pitched, so that the chanterelle is the first course, the next pair of strings is the second course, etc. Thus an 8-course Renaissance lute usually has 15 strings, and a 13-course Baroque lute has 24.
