::Thank you, that was my impression also. As far as I can see that leaves the falling augmented octave/augmented unison image and its apparently unrelated caption without any reference; I removed it yesterday for that reason, but see it is back today, together with some new unreferenced text which I suggest also be removed. I also don't understand why we need two references for the caption to the augmented unison image, "Augmented unison on C"; is that so likely to be challenged? Could we perhaps discuss what further changes are needed here now?
