The Trait de l'harmonie of Jen-Philippe Rameau is one of the most important books in the history of Western music. Written while Rameau was still a relatively obscure organist and music master at Clermont-Ferrand, the book received but one printing during Rameau's life, in 1722, shortly before he settled in Paris. The Trait was immediately recognized as a profound advance in musical theory, however, and it established Rameau's reputation as a theorist. His book was the first to codify those principles of tonality that were to dominate the music of the West for almost two centuries. Even today the theories of Rameau remain the basis for the study of harmony.
Rameau's Trait de l'harmonie is divided into four books, the first of which presents the mathematical basis from which Rameau sought to derive his theories. Book Two may be considered the most important section of the Trait ; in it Rameau generates his entire harmonic system from fundamental principles, explaining intervals, chords, and modes -- everything, in fact, essential to musical composition in tonal style. Working from the principles developed in Books One and Two, Book Three treats the practical rules of composition, including such topics as harmonic modulation and chord progressions. Book Four concerns the practical art of accompaniment on harpsichord or organ, including the realization of a figured bass. Corrections added by Rameau in a supplement are included in the text, and all the musical examples have been reset in modern musical notation. In addition, two pages from a unique copy of the first issue of the first edition are given in facsimile. The translator's introduction discusses the history of the work, Rameau's mathematics, and his place in the history of music theory.

I wouldn’t recommend this for strong chewers.
Color: Orange, Color: Orange
Is it fun? Sure. Was it easy to charge and set up? Yep. That being said, this toy kind of fell flat for me. It really didn’t do any big movements once charged that I expected it to, so that was a bummer. I initially got it for my dog, but my cats were more interested in this than my dog was. The battery does seem to last a long time and the motor is pretty quiet. I WOULD NOT recommend this toy for strong chewers as the material for this is a foam rubber and I don’t think it’s durable enough for strong chewers. While the material makes this ball extremely lightweight for more movement, a strong chewer would have this disintegrated in five minutes flat. My Dog is a super strong chewer. I don’t think I would feel comfortable leaving him unattended with this because I know he would destroy it.

Well-designed and quiet, but didn’t keep my dog interested
Color: Blue
My dog was interested in this at first, but she would lose interest after a few minutes and move on. I do like that it’s quieter than the hard plastic ball toys, and the charge lasts well. The internal charging port that twists closed is also a nice design feature. That said, it will occasionally turn on by itself, which can be a little surprising. Overall, it has some nice features, but it just didn’t keep my dog engaged.

Good - for a few hours
Color: Blue, Color: Blue
Concept is fantastic. Dog loved it. Problem is that she figured out how to open it within two hours of play. The robot core, alas, did not survive. In the photo, you see a tooth went cleanly into the button and that was the end of the toy.

The most engaging interactive toy for my Border Collie
Color: Orange, Color: Orange
My Border Collie is not a big ball player. He prefers tug type games and actually gives me a look like, “Are you stupid? I’m not going to keep bringing that to you if all you’re going to do is throw it away again!” after about the third time I throw a ball for him to fetch. However, I can only play tug so often and I need him to be entertained and engaged as much as possible. I got him a smaller, non-padded ball like this hoping he would like the interactive aspect of it. He did- he actually loved it! But it was loud, hard on his teeth, would come apart periodically, and he kept hitting the off button when playing with it. It drove me crazy. This one is so much better overall! The soft outer shell is not only easier on his teeth, but it is super resilient to biting and chewing. He actually likes to carry this thing around in his mouth while it’s bouncing and vibrating. The three modes give great flexibility for different kinds of play. His favorite is the most active mode: the ball reacts to touch and practically bounces itself across the floor when he touches it with his paw or mouth. I will point out that in one of the modes, I thought the battery wasn’t charged or there was a motor issue because it’s very subdued movement; however, it’s just set up as a low-key option. Be sure to check out each mode to see which works best for your dog at different times. I can’t say enough about this ball- I have been so pleasantly surprised by how much he loves it. The rechargeable feature is super convenient, it’s big enough to not get stuck under the couch, and it automatically shuts off based on whichever mode it’s set on. As the owner of a busy, super-smart dog who needs to be engaged in mental and physical activity, I think this all is worth every penny. In fact, I’m buying one for a friend who has a Border Collie pup with lots of energy to burn! I highly recommend this toy- it’s the most engaging toy I’ve found that Finn will play with on his own.
