First, it manifests itself as a form of [[tuning map]]. Its columns represent tunings of [[formal prime]]s in terms of [[monzo]]s. The tuning map in the logarithmic scale can be obtained by multiplying the projection map by the [[JIP]] on the left.

where T is the tuning map, J the JIP, and P the projection map.

The projection map multipled by a [[Temperament mapping matrices|temperament map]] on the left yields its [[Tmonzos and tvals|tempered monzos]]. In particular, if V is the temperament map of P, then
