'''19712/19683''', the '''symbiotic comma''', also known as the '''symbiosis | '''19712/19683''', the '''symbiotic comma''', also known as the '''symbiosis''' or '''symbiosma''', is an [[11-limit]] [[unnoticeable comma]] measuring about 2.55 [[cent]]s. It gets its names from the fact that it is tempered out in such notable temperaments as [[vishnu]], [[newt]], [[kwai]], [[supers]], [[guiron]] and [[amity]], and, from the fact that it also makes a good extension to a number of other temperaments such as [[Canou family|canou]]. It is the difference between an [[2187/2048|apotome (2187/2048)]] and an [[77/72|undecimal secor (77/72)]] – the latter of which can be broken down into a [[33/32]] quartertone stacked on top of [[28/27]]. Alternatively stated, it identifies [[11/8]] by an apotome over [[9/7]]. It factors into ([[4375/4374]])([[5632/5625]]), and moreover, into the [[quartisma]] and the [[nexus comma]]. | ||
