Just checking out where the name comes from.
I know a couple of Trovatos (trovato = found), but that seems to be another, if related, case.
Best of all is the Greek, tropos, in this Shitipedia entry:
The name "troubadour" and its cognates in other languages—trov(i)èro and then trovatore in Italian, trovador in Spanish, trobador in Catalan—are of disputed origin.
Latin
The English word "troubadour" comes by way of Old French from the Occitan word trobador, the oblique case of the nominative trobaire, a substantive of the verb trobar, which is derived from the hypothetical Late Latin *tropāre, in turn from tropus, meaning a trope, from Greek τρόπος (tropos), meaning "turn, manner". Another possible Latin root is turbare, to upset or (over)turn. Trobar is cognative with the modern French word trouver, meaning "to find". Whereas French trouver became trouvère, the nominative form, instead of the oblique trouveor or trouveur, the French language adopted the Occitan oblique case and from there it entered English. The general sense of "trobar" in Occitan is "invent" or "compose" and this is how it is commonly translated. A troubadour thus composed his own work, whereas a joglar performed only that of others. This etymology is supported by the French dictionaries Académie Française, Larousse, and Petit Robert.
Not surprisingly, the Greek → Latin → Occitan → French → English hypothesis has been widely supported by those who find the origins of troubadour poetry in classical Latin forms or in medieval Latin liturgies, such as Peter Dronke and Reto Bezzola.
Arabic
There is a second, less traditional and less popular, theory as to the etymology of the word trobar. It has the support of some, such as María Rosa Menocal, in the camp which seeks the troubadours' origins in Arabic Andalusian musical practices. According to them, the Arabic word tarrab, "to sing", is the root of trobar.
Some proponents of this theory argue, on cultural grounds, that both etymologies may well be correct, and that there may have been a conscious poetic exploitation of the phonological coincidence between trobar and the triliteral Arabic root TRB when sacred Sufi Islamic musical forms with a love theme were first exported from Al-Andalus to southern France. It has also been pointed out that the concepts of "finding", "music", "love", and "ardour"—the precise semantic field attached to the word troubadour—are allied in Arabic under a single root (WJD) that plays a major role in Sufic discussions of music, and that the word troubadour may in part reflect this.
