The revision contents are below, presented both in the original Wikispaces Wikitext format, and in HTML exactly as Wikispaces rendered it.

Original Wikitext content:

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.

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

<html><head><title>Gallery of 12-tone Just Intonation Scales</title></head><body>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.<br />
<br />
One approach to making just intonation not only practical but easy is to map an <a class="wiki_link" href="/Period%20scale">octave-repeating</a> 12-tone JI scale to a standard keyboard. This page collects some of these scales, and a <a class="wiki_link" href="/Gallery%20of%2012-note%20tempered%20scales">companion page</a> does the same with tempered scales.<br />
