@kadse@chaos.social Western music interval chord names come from counting the notes in a major scale: a third is the interval between the first and third notes in that scale, a sixth the interval between the first and sixth notes, etcetera. Yes, some of these notes have notes between them, but for some reason they don't count, and instead we'll modify another interval's name, like "minor third" or "augmented sixth" (I'm not saying it's a good system, just explaining what it is). The intervals that @elilla@elilla@thetransagenda.gay@transmom.love describes are based on ratios of frequencies (much simpler explanation!). Some of these have corresponding western interval names, but the numbering/naming is completely unrelated. Therefore, the interval with a frequency ratio of 6:7 is not related to the sixth or seventh (however pretty each of these intervals might be)
