The revision contents are below, presented both in the original Wikispaces Wikitext format, and in HTML exactly as Wikispaces rendered it.&amp;lt;br&amp;gt;&lt;br /&gt;

&lt;br /&gt;
Generalized, &amp;quot;fluid tuning&amp;quot; could mean any instrument which offers a &amp;quot;temporarily fixed&amp;quot; tuning. That is, at any one moment, the instrument offers a finite set of fixed pitches, yet it also allows the //continuous// change of what those pitches are. Each pitch-producing mechanism in the instrument (each &amp;quot;voice&amp;quot;) then has a defined frequency range. A fluid tuning could then be defined by a set of interval ranges instead of a set of single pitches.&lt;br /&gt;
&lt;br /&gt;
Defined in that way, instruments with fluid tuning also include the [[http://www.youtube.com/watch?v=YcuAk5UY5g8|pitch bending thumb piano]], the moveable-frets guitar, and perhaps even the [[http://www.oneringzero.com/?page_id=57|claviola]], as well as a number of interfaces made possible with computers.&amp;lt;/pre&amp;gt;&amp;lt;/div&amp;gt;&lt;br /&gt;
