One notable property of 53EDO is that it offers good approximations for both pure and pythagorean major thirds.

The perfect fifth is almost perfectly equal to the just interval 3/2, with only a 0.07 cent difference! 53EDO can be considered an extended Pythagorean tuning using the notes: 0, 4, 9, 13, 18, 22, 26/27, 31, 35, 40, 44, 49, 53. The thirds are close to just as well, and therefore 5-limit tuning can closely be approximated e.g. instead of 13- and 18- degree intervals which are extremely close to the Pythagorean minor(32/27) and major(81/64) thirds respectively, the 14- and 17- degree intervals which are very close to 5/4 and 6/5, respectively, can be used. Some feel that the 5/4 and 6/5 intervals are more "consonant" or "harmonic" because they involve simpler numbers, but others feel that the Pythagorean intervals are more "consonant" or "harmonic" because the numbers in the ratios only have prime factors of 2 and 3 (not 5, which is "less consonant" according to that view). Because 1 degree is very close to both the [[Syntonic Comma|Syntonic]] and [[Pythagorean comma|Pythagorean commas]], 53EDO is very flexible and wolf intervals can be avoided simply by using the note above or below the note in the scale rather than retuning the note in the scale.

The perfect fifth is almost perfectly equal to the just interval 3/2, with only a 0.07 cent difference! 53EDO can be considered an extended Pythagorean tuning using the notes: 0, 4, 9, 13, 18, 22, 26/27, 31, 35, 40, 44, 49, 53.
