=<span style="color: #1300ff; font-family: 'Times New Roman',Times,serif; font-size: 113%;">17 tone equal temperament</span>= 
[[toc]]
**17-EDO** divides the octave in 17 equal steps, each 70.588 [[cent|cents]] in size. It is the seventh [[prime numbers|prime]] edo, following [[13edo]] and coming before [[19edo]].

==Theory== 
An introduction to 17-EDO theory, through the eyes of the [[SeventeenTonePianoProject]]: [[SeventeenTheory]].
Another introduction into 17-EDO theory: [[http://xenharmony.wikispaces.com/space/showimage/17puzzle.pdf|The 17-tone Puzzle]] by George Secor.
[[17edo Solfege]]. [[17edo tetrachords]]. [[http://microtonalismo.com/proyecto-xvii|Proyect 17-Perú]]

17-EDO can plausibly be treated as a 2.3.25.7.11.13 subgroup temperament, for which it is quite accurate (though the 7-limit ratios are generally not as well-represented as those of the other integers).

Note that despite their relatively large size, the 17-comma, the avicennma and the chromatic semitone are all tempered out by the 13-limit patent val, as stated.

<!-- ws:end:WikiTextTocRule:45 --><strong>17-EDO</strong> divides the octave in 17 equal steps, each 70.588 <a class="wiki_link" href="/cent">cents</a> in size. It is the seventh <a class="wiki_link" href="/prime%20numbers">prime</a> edo, following <a class="wiki_link" href="/13edo">13edo</a> and coming before <a class="wiki_link" href="/19edo">19edo</a>.<br />

 An introduction to 17-EDO theory, through the eyes of the <a class="wiki_link" href="/SeventeenTonePianoProject">SeventeenTonePianoProject</a>: <a class="wiki_link" href="/SeventeenTheory">SeventeenTheory</a>.<br />
Another introduction into 17-EDO theory: <a class="wiki_link_ext" href="http://xenharmony.wikispaces.com/space/showimage/17puzzle.pdf" rel="nofollow">The 17-tone Puzzle</a> by George Secor.<br />

<br />
17-EDO can plausibly be treated as a 2.3.25.7.11.13 subgroup temperament, for which it is quite accurate (though the 7-limit ratios are generally not as well-represented as those of the other integers).<br />
