::: I should also mention that this is how I make retunings of other EDOs like in "[[:File:Space Tour.mp3|Space Tour]]". Most of what I had to do for this is map the intervals comprising the steps of the smaller EDOs to the nearest step in 159edo, through there were times where I had to choose which mapping to use. --[[User:Aura|Aura]] ([[User talk:Aura|talk]]) 15:39, 18 January 2021 (UTC) | ::: I should also mention that this is how I make retunings of other EDOs like in "[[:File:Space Tour.mp3|Space Tour]]".

I notice that in Wolfram Alpha, 49/32 effectively has two separate mappings, the first, given by round(log2(49/32)*159), is 98 steps, while the second, given by {159, round(log2(3)*159), round(log2(5)*159), round(log2(7)*159)}.{-5, 0, 0, 2}, is 97 steps. The first one is direct mapping, but what is the proper term for the second one | I notice that in Wolfram Alpha, 49/32 effectively has two separate mappings, the first, given by round(log2(49/32)*159), is 98 steps, while the second, given by {159, round(log2(3)*159), round(log2(5)*159), round(log2(7)*159)}.{-5, 0, 0, 2}, is 97 steps. The first one is "direct mapping", but what is the proper term for the second one? Is it "consistent mapping"? I think this article could be expanded by describing the relationship between these two different types of mappings. --[[User:Aura|Aura]] ([[User talk:Aura|talk]]) 22:20, 18 January 2021 (UTC) | ||
