While there is no agreed-upon notation system for tricot, the following is based on interpreting the generator as a supermajor second. ^^C and vDb are enharmonic. | While there is no agreed-upon notation system for tricot, the following is based on interpreting the generator as a supermajor second. ^^C and vDb are enharmonic. | ||

A notable feature of tricot is the small diesis, known as the [[quark]], encountered after 5 steps, which represents one-third of a [[diatonic semitone]]. This makes tricot scales cluster around [[5edo]]. | A notable feature of tricot is the small diesis, known as the [[quark]], encountered after 5 steps, which represents one-third of a [[diatonic semitone]].

[[Slendric]] is the most obvious [[7-limit]] interpretation of tricot, where the generator is [[8/7]] and three of them stack to make [[3/2]]. It is best tuned with a slightly flattened 3/2, or equivalently a slightly sharpened 8/7, but the just tuning of either works. | [[Slendric]] is the most obvious [[7-limit]] interpretation of tricot, where the generator is [[8/7]] and three of them stack to make [[3/2]].
