x1 is a note low in frequency/pitch produced by x2
cf. ganra, tonga. See also jakto'a for "high-pitched". "wide" refers to the wavelength of a note low in frequency, as well as the characteristics of an object which produces such a note. Alternative to existing word cmato'a, which is ambiguous due to the fact that "small" could refer to either the frequency in Hertz (i.e., low pitch) or the wavelength (i.e. high pitch).
