'''8L 5s''' or '''petroid''' (named after [[5L 3s/Temperaments#Petrtri|petrtri]] temperament) is a scale pattern that expands on oneirotonic ([[5L 3s]]). This MOS is the chromatic scale of Semidim, Tridec, Ammonite and Petrtri temperaments. It represents tempered chains of the 13:10 or 17:13 | '''8L 5s''' or '''petroid''' (named after [[5L 3s/Temperaments#Petrtri|petrtri]] temperament) is a scale pattern that expands on oneirotonic ([[5L 3s]]). This MOS is the chromatic scale of Semidim, Tridec, Ammonite and Petrtri temperaments. It represents tempered chains of the 13:10 or 17:13 [[semisixth]], thus rendering 10:13:17 as an equidistant triad and tempering out 170:169. Also, the ratio between the generator of this MOS and its inverse is close to [[logarithmic phi]], or even logarithmic phi itself. | ||
