"So what did the women play? A very tight self-regulation of activity in the name of "maintaining reputation" limited musical options for women. Many wealthy women played harpsichords on which they practiced and performed for family and friends. The other instrument of choice for women was what we call today an English guitar, a now extinct 10-string version of a Renaissance cittern with a flat back and a tear-drop shape, tuned to an open C chord, seen in the picture above. The grandmother of our modern guitar was around also, but not as popular; it is called today a Baroque guitar, and it was a small version of a classical guitar with gut strings, frets of gut tied around the neck, and strung as a modern 12-string without the bass E strings, so it was also a 10 stringed instrument. It wasn't until around 1820 that the standard guitar had 6 strings. Women also played harps, but not before the end of the 18th century."
