doesn't show temperament data anymore as zinc got moved to landscape temps and this is just now a description of what makes zinc notable beyond belonging in landscape family |

Within the reach of a standard 128-note MIDI keyboard, zinc has mos scales of size 60, 90, and 120. These scales are significantly distinct from either landscape rank-3 scales or the 10th-octave mos scales that produce neon or its descendant temperaments like [[deca]]. The 120-tone mos has [[65/64]] within reach. | Within the reach of a standard 128-note MIDI keyboard, zinc has mos scales of size 60, 90, and 120.

=== Oyster === | |||
Oyster is a 2.7.11.19 restriction of zinc of reasonably low badness and contains all the harmonics within the reach of a standard MIDI 128-note keyboard ― 120 notes is sufficient to cover all the temperament for the subgroup. Furthermore, [[7/4]] is the generator and it is of badness comparable to full-limit zinc variants. As harmonics 3 and 5 are not used, oyster is neither a landscape nor neon temperament. | |||
Named so because oysters are the biggest source of the element zinc, the namesake of the temperament it is derived of. | |||
