In the 5-limit, it supports [[gross]], which is a very high-accuracy temperament. The 118-tone [[maximal evenness]] scale produced by gross is [[concoctic]], since it uses 118\1547 as the generator. In addition, 1547edo tempers out the [[septendecima]] and thus supports the [[chlorine]] temperament in 5-limit and also in the 7-limit. 1547edo tempers out the 5-limit comma {{monzo| 236 -61 -60 }}, thus associating a stack of sixty [[15/8]]'s with [[4/3]], and sixty-one of them make [[5/4]]. | In the 5-limit, it supports [[gross]], which is a very high-accuracy temperament.

It also supports [[semidimi]], the 171 & 1376 temperament. In the 11-limit, it tempers out 117649/117612, and is a tuning for the rank-3 temperament [[heimdall]].
