'''121/81''', the '''Alpharabian narrow fifth''' or '''lolo 5th''' (694.8¢), is a Lulu comma [[243/242]] (7.1¢) below the just fifth [[3/2]].  It is the interval created by stacking two [[11/9]] neutral thirds, and can be considered a [[meantone]] fifth. It differs from the marvellous fifth [[112/75]] by [[3025/3024]]. Since [[38edo]] represents 11/9 near perfectly, it also represents this near perfectly as well.

When treated as a meantone fifth, it is incredibly close to [[1/3-comma meantone]], three of these intervals differing from [[5/3]] by only the [[parimo]].
