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''', 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¢.
