Juan Carlos Amat (c.1572 - 1642)
Today, Juan Carlos Amat’s treatist, Guitarra española, survives him. Interestingly, the only extant edition of the treatise is a reprint from 1626. A letter of dedication at the beginning of the treatise is dated 1596, which is presumably the date of the original publication. Amat’s book did not include any real pieces. Instead, it’s a 9 chapter work that describes stringing, tuning, and playing all the major and minor chords on the five-course guitar.
