Pianos are frequently tuned with stretched octaves anyway due to the slight inharmonicity inherent in their strings, which makes 19edo a promising option for pianos with split sharps. | Pianos are frequently tuned with stretched octaves anyway due to the slight [[timbre|inharmonicity]] inherent in their strings, which makes 19edo a promising option for pianos with split sharps. | ||
Octave stretching also means that an out-of-tune interval can be replaced with a compounded or inverted version of it which is near-[[just]]. For example, if we are using [[49ed6]] or [[30ed3]] (which tune 6:1 and 3:1 just and have octaves stretched by 2.8 and 4.57{{c}}, respectively), then we have near-just minor thirds (6:5), compound major thirds (as 5:1), and compound fifths (as 6:1), giving us versions of everything in the 5-limit [[tonality diamond]]. The compound major and minor triads (1:5:6 and 30:6:5) are near-just as well. | Octave stretching also means that an out-of-tune interval can be replaced with a compounded or inverted version of it which is near-[[just]].
