Musicians and composers just getting into the area of microtuning might, in an initial survey of the available resources on tuning around the web, encounter a barrage of intimidating jargon and mathematical concepts. Fortunately, a composer or player need not worry about the math side of things! This article suggests a number of ways to jump right in and start putting the //products// of tuning theory to work.

* For each temperament you're interested in, learn how the different tempered JI intervals relate to each other in that temperament. For example, in porcupine two 11/10s equals one 6/5, and that interval (11/10) also represents 12/11 and 10/9 at the same time.

"For starters, you might want to mess around with what's called "porcupine" temperament in 22-EDO. The base diatonic-sized scale is (as steps out of 22-EDO) 4 3 3 3 3 3 3, and you can chromatically alter anything in that scale you want by 1 step out of 22. For instance, if you flat the 7, you get the scale 4 3 3 3 3 2 4, which is nice because it has a 4:5:6:7:9:11 chord in it. There's another "superdiatonic" scale at 1 3 3 3 3 3 3 3 which you can morph the above into if you want, and a 15-note chromatic scale at 1 1 2 1 2 1 2 1 2 1 2 1 2 1 2; feel free to not stick dogmatically to these exact scales but to change them as you desire.

If you don't mind a bit less accuracy in representing harmonic ratios, the above temperament also exists in 15-EDO, except the diatonic-sized scale is now 3 2 2 2 2 2 2, the superdiatonic is 1 2 2 2 2 2 2 2, and the chromatic scale is all of 15-EDO. 15-EDO also has a really nice "symmetrical diatonic" scale, called the Blackwood-10 scale, which is 2 1 2 1 2 1 2 1 2 1. Play around with major and minor chords in this scale a bit, and transpose them up and down the shape of the scale, and you'll see why it's so magical - the circle of fifths is only five steps long."

===World Music Scales===  
If you don't care about harmonic ratios at all, but perhaps instead care about world music, then you might enjoy 16-EDO, which contains in it a wonderful extension of both gamelan music and Chopi timbila music; 5 2 2 5 2 is a great pelog and 3 3 3 4 3 works as slendro.

Both of these scales can be "extended" into "diatonic"-sized versions, such as the 2 3 2 2 3 2 2 mavila-7 scale, named after the Chopi village which used a very similar scale to tune its xylophones. This scale is really nuts because of its "anti-diatonic" structure; the 675 cent fifths are so flat that four of them gives you a 300 cent minor third instead of the more familiar major third. As a result, there's now two large seconds and five small seconds, four major thirds and three minor thirds, etc, which is the complete opposite of what you're used to. There's even a 2 2 2 1 2 2 2 2 1 9-note superdiatonic scale to play with if you want, and of course you should always feel free to chromatically alter things!

The 3 3 3 4 3 slendro can turn into the 3 3 3 1 3 3 "slendric-6" scale as well, though I prefer the 3 3 1 3 3 3 mode. This scale is nice because it sounds kind of like a "warped diatonic" scale. Chromatically altering things by 2 steps here, instead of 1 step, sounds really nice.

World music fans might also like 17-EDO, which contains within it a system of scales very similar to the maqamat used in the middle east; 24-EDO and 31-EDO contain the same features but with better intonation, albeit at the cost of more notes, but you can always use smaller 17-note subsets if you want.

17-EDO is also notable for containing a very interesting diatonic scale, for which the fifths are slightly sharp from what we're used to (and rather pleasantly, I think). As a result, the "major thirds" in the diatonic scale end up being closer to 9/7 than 5/4, and the "minor thirds" end up being closer to 7/6 than 6/5. Major chords are thus a bit less "sweet" than usual, though I don't mind them much, whereas minor chords are now 6:7:9 and have a sort of "subminor" flavor to them. You can also think about ditching "thirds," and instead harmonizing this scale in terms of 4:6:7 chords, of which there are four instead of three. I really like this because it has a very calm, quiet, meditative sound to it. This is called "superpyth" temperament, short for "superpythagorean," because the fifths are a bit sharp of pythagorean (instead of a bit flat as usual).

For people looking to mess with higher-limit stuff, 17-EDO is also really notable for giving decent 13-limit harmony, with the caveat that there's no good representation for 5/1 and other ratios containing 5.

===Historical Tunings and Extended Meantone===  
===Historical Tunings and Extended Meantone===  
Some people are really interested in historic tunings for meantone, and perhaps extending them in ways that go beyond the 12-EDO "closure" that we ended up going with. So if you really want to get away from the notion that C# has to equal Db, and want to explore extended meantone, there's a number of great options for you.

So if you really want to get away from the notion that C# has to equal Db, and want to explore extended meantone, there's a number of great options for you.


A particularly well-known historical meantone tuning is 1/4-comma meantone, where the 3/2's are a bit flatter than we're used to, but the major thirds are exactly 5/4. What's particularly interesting is that this same tuning turns the augmented sixth, e.g. C-A#, into an almost exact 7/4 - so you can treat it as a 7-limit tuning.

As mentioned before, all of the "maqamic" stuff from 17-EDO and 24-EDO is also in 31-EDO, but now the major thirds are 5/4. So there's that as well.

Alternatively, you have 19-EDO, which is very close to 1/3-comma meantone, for which the minor thirds are pure 6/5's. This tuning can also play virtually all common practice music. While 31-EDO does a lot better in the 11-limit, 19-EDO still has an OK 7-limit. However, what you lose in intonation, you gain by having a really badass set of novel enharmonic equivalences: instead of C# = Db, it's now C# = Dbb. This leads to a really tight-knit "structure" with tons of enharmonic equivalences everywhere, much like in 12-EDO, and unlike 31-EDO, the enharmonic equivalences are really simple and can be made use of.

For instance, there's now an entire circle of major thirds which doesn't close at the octave after 3 iterations, but which does sync up with the perfect twelfth after 5 iterations. Also, the "diesis" between A# and Bb is now the same as the "chromatic semitone" between A# and Ax, which you can exploit to make some pretty neat musical effects. You've also got some very novel scales, such as the "semaphore-9" scale, which is 3 3 1 3 1 3 1 3 1; subminor and supermajor chords are everywhere here.

Both of these scales can be &amp;quot;extended&amp;quot; into &amp;quot;diatonic&amp;quot;-sized versions, such as the 2 3 2 2 3 2 2 mavila-7 scale, named after the Chopi village which used a very similar scale to tune its xylophones. This scale is really nuts because of its &amp;quot;anti-diatonic&amp;quot; structure; the 675 cent fifths are so flat that four of them gives you a 300 cent minor third instead of the more familiar major third. As a result, there's now two large seconds and five small seconds, four major thirds and three minor thirds, etc, which is the complete opposite of what you're used to. There's even a 2 2 2 1 2 2 2 2 1 9-note superdiatonic scale to play with if you want, and of course you should always feel free to chromatically alter things!&lt;br /&gt;

The 3 3 3 4 3 slendro can turn into the 3 3 3 1 3 3 &amp;quot;slendric-6&amp;quot; scale as well, though I prefer the 3 3 1 3 3 3 mode. This scale is nice because it sounds kind of like a &amp;quot;warped diatonic&amp;quot; scale. Chromatically altering things by 2 steps here, instead of 1 step, sounds really nice.&lt;br /&gt;

World music fans might also like 17-EDO, which contains within it a system of scales very similar to the maqamat used in the middle east; 24-EDO and 31-EDO contain the same features but with better intonation, albeit at the cost of more notes, but you can always use smaller 17-note subsets if you want.&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
17-EDO is also notable for containing a very interesting diatonic scale, for which the fifths are slightly sharp from what we're used to (and rather pleasantly, I think). As a result, the &amp;quot;major thirds&amp;quot; in the diatonic scale end up being closer to 9/7 than 5/4, and the &amp;quot;minor thirds&amp;quot; end up being closer to 7/6 than 6/5. Major chords are thus a bit less &amp;quot;sweet&amp;quot; than usual, though I don't mind them much, whereas minor chords are now 6:7:9 and have a sort of &amp;quot;subminor&amp;quot; flavor to them. You can also think about ditching &amp;quot;thirds,&amp;quot; and instead harmonizing this scale in terms of 4:6:7 chords, of which there are four instead of three. I really like this because it has a very calm, quiet, meditative sound to it. This is called &amp;quot;superpyth&amp;quot; temperament, short for &amp;quot;superpythagorean,&amp;quot; because the fifths are a bit sharp of pythagorean (instead of a bit flat as usual).&lt;br /&gt;

For people looking to mess with higher-limit stuff, 17-EDO is also really notable for giving decent 13-limit harmony, with the caveat that there's no good representation for 5/1 and other ratios containing 5.&lt;br /&gt;

  Some people are really interested in historic tunings for meantone, and perhaps extending them in ways that go beyond the 12-EDO &amp;quot;closure&amp;quot; that we ended up going with. So if you really want to get away from the notion that C# has to equal Db, and want to explore extended meantone, there's a number of great options for you.&lt;br /&gt;

A particularly well-known historical meantone tuning is 1/4-comma meantone, where the 3/2's are a bit flatter than we're used to, but the major thirds are exactly 5/4. What's particularly interesting is that this same tuning turns the augmented sixth, e.g. C-A#, into an almost exact 7/4 - so you can treat it as a 7-limit tuning.&lt;br /&gt;

As mentioned before, all of the &amp;quot;maqamic&amp;quot; stuff from 17-EDO and 24-EDO is also in 31-EDO, but now the major thirds are 5/4. So there's that as well.&lt;br /&gt;

&lt;br /&gt;
Alternatively, you have 19-EDO, which is very close to 1/3-comma meantone, for which the minor thirds are pure 6/5's. This tuning can also play virtually all common practice music. While 31-EDO does a lot better in the 11-limit, 19-EDO still has an OK 7-limit. However, what you lose in intonation, you gain by having a really badass set of novel enharmonic equivalences: instead of C# &lt;!-- ws:start:WikiTextHeadingRule:16:&amp;lt;h1&amp;gt; --&gt;&lt;h1 id="toc8"&gt;&lt;a name="Db, it's now C#"&gt;&lt;/a&gt;&lt;!-- ws:end:WikiTextHeadingRule:16 --&gt; Db, it's now C# &lt;/h1&gt;

This leads to a really tight-knit &amp;quot;structure&amp;quot; with tons of enharmonic equivalences everywhere, much like in 12-EDO, and unlike 31-EDO, the enharmonic equivalences are really simple and can be made use of.&lt;br /&gt;

For instance, there's now an entire circle of major thirds which doesn't close at the octave after 3 iterations, but which does sync up with the perfect twelfth after 5 iterations. Also, the &amp;quot;diesis&amp;quot; between A# and Bb is now the same as the &amp;quot;chromatic semitone&amp;quot; between A# and Ax, which you can exploit to make some pretty neat musical effects. You've also got some very novel scales, such as the &amp;quot;semaphore-9&amp;quot; scale, which is 3 3 1 3 1 3 1 3 1; subminor and supermajor chords are everywhere here.&lt;br /&gt;

You can do all sorts of amazing stuff with 19-EDO if you want, and make it sound almost exactly like ordinary 12-EDO music too, but then depart from it into some rather mind-blowing stuff if you want.&lt;br /&gt;
