The '''Pythagorean augmented fifth''', '''6561/4096''', may be reached by stacking two [[81/64]] major thirds. The Medieval music theorist {{w|Jacques de Liège}} referred to it as the '''tetratone''' (akin to the [[ditone]] and [[729/512|tritone]]), as it may be reached by stacking four [[9/8|(Pythagorean whole) tones (9/8)]], and he considered it highly discordant.<ref>''Pythagorean Tuning and Medieval Polyphony'', Margo Schulter, 10 June 1998</ref> It differs from [[8/5]] by the [[schisma]], and from [[3/2]] by the [[apotome]].
