What did Jongleurs and troubadours performed?
Jongleurs and troubadours were minstrels, who travelled around France in the Middle Ages, performing songs which they usually wrote themselves, accompanying themselves on the lute and other stringed instruments. If they lived in the 21st century, we'd call them singer-songwriters! In fact, their lyrics are some of the earliest examples of love poetry (in French, also in the Provencal language).
