In the context of just intonation, ratios are almost always used to label and identify intervals and chords. However, the use of ratios to identify intervals and chords in tempered scales is also common - in these cases, it is implied that the notes are in the //approximate// ratio indicated. For example, a common shorthand expression might be //"4:6:7:9:11 chords in 17-EDO"// - which really means //"The chords in which the notes are in the approximate ratio of 4:6:7:9:11 in 17-EDO".//</pre></div> | In the context of just intonation, ratios are almost always used to label and identify intervals and chords.
