Just Intonation is an infinite universe. A justly-intoned pentatonic can be very effective in the hands of a sensitive composer, and in this electronic age that same composer on another day can use a scale with hundreds of notes in an octave.

One approach to making just intonation not only practical but easy is to map an octave-repeating 12-tone JI scale to a standard keyboard. This page collects some of these scales, and a companion page does the same for tempered scales.
