Jean-Philippe Rameau - 3 Ouvertures: Castor et Pollux, Naïs & Platée 

Not unusual for those times.

They sure did. It's nice to get exposed to this from time to time.

^ Yes, the French have always prided themselves on being different, even in the baroque, haha.

Check out his Treatise on Harmony, it includes a chapter with probably every use of clefs at the time.

^ The maddening thing about Rameau is that he was indeed a technician and a theorist. After all, he was the one who corrected the erroneous belief at the time that inverted chords of the same sonority were different chords from one another altogether. However, in spite of his mathematical approach to music, much of his music is stunningly beautiful and holds a great deal of character. Apparently, while at the harpsichord experimenting/composing, he would come alive. When he closed the lid, he receded back into his very non-personable and cold shell.

@@rominn2184 I wouldn't say erroneous. Music was just thought of much differently at this time. Even Bach himself didn't exactly "buy" the whole inversions thing because not all inversions of chords in functional contexts are equal. In counterpoint, you would never end a tune on a second inversion tonic chord (it doesn't even have tonic function in modern music theory) and chords based on the third scale degree were almost always in first inversion according to inversion theory. Not all inversions are equal in counterpoint based music. Just my two cents.

if only mathematics were so harmonious and so ispirating !
