An uprooted interval is in the context of octave equivalence a rational interval under a power of 2, i.e. of the form [math]\displaystyle{ 2^n/x }[/math] for any positive integer x and nonnegative integer n.
Analysing an uprooted interval requires us to think in terms of subharmonic timbre, where the virtual fundamental would be of the same pitch as the treble, or whole octaves above the treble. In other words, the virtual fundamental would be in the same pitch class as the treble. This gives uprooted intervals the distinct characteristic of securing its own treble than suggesting other pitch classes.
