In [[11-limit]] [[just intonation]], '''128/99''' is an '''undecimal subfourth''' measuring about 444.8¢. It is the inversion of [[99/64]], the undecimal superfifth. This interval is also known as the '''minor fourth''' through analogy with [[11/8]] being the "major fourth" as named by [[Ivan Wyschnegradsky]], and can additionally be somewhat similarly dubbed the '''Alpharabian paraminor fourth''' or even the '''just paraminor fourth'''. It is distinguished from the simpler [[22/17]] by the [[1089/1088|twosquare comma]]. | In [[11-limit]] [[just intonation]], '''128/99''' is an '''undecimal subfourth''' measuring about 444.8¢.
