This is a collection of [[rank-2 temperament|rank-2]] '''landscape microtemperaments''', which [[tempering out|temper out]] the [[landscape comma]] ({{monzo|legend=1| -4 6 -6 3 }}, [[ratio]]: 250047/250000). For the [[rank-3 temperament]], see [[Landscape family #Landscape]].


'''Landscape microtemperaments''' are rank two temperaments tempering out the [[landscape comma]], |-4 6 -6 3> = 250047/250000. This is the amount by which three [[63/50]] intervals exceed an octave. Tempering 63/50 interval into one degree of 3edo (exact 400 cents) is highly characteristic of landscape tempering; any tuning system (41edo, for example) which the number of divisions of the octave is not multiple of 3 cannot be tempering out the landscape comma.

=== Vasca ===
Vasca can be described as the 357 & 525 temperament, extended as high as the 23-limit. It tempers out the {{monzo| 95 0 0 0 0 0 0 0 -21 }}, and sets a stack of twenty-one [[23/16]]'s equal with eleven octaves. The name derives from elements vanadium (23) and scandium (21), since this uses the 23rd harmonic, which itself is extremely well represented in 21edo.
