théorbe de pièces: Gavotte en Rondeau de Mr. de Visée

Gavotte on page 375 (Vaudry de Saizenay manuscript). One of three gavottes, part of 17 pieces listed in the key of G. re sol mineur. In this recording it sounds in C minor because of the higher tuning of théorbe de pièces.
Why is it called G.re sol tierce mineure?

The little theorbo sounds great! Concerning your question about "G. re sol": the key denominations in the MS Saizenay use the old hexachord terminology from the modal counterpoint system of the sixtenth century. In this system, the note G could have different functions depending on the context: it can be a Ut when the context is G Major, a Sol when the context is C Major, or a Re when the context is G Minor. The third note after the Re is a Fa, therby resulting in a minor third (tierce mineur). It is weird that this system is used, because there are pieces in this MS in impossible keys from a 16c standpoint, e.g. F# Minor.
