Many equal temperaments and circular tunings could also be considered meantones, yet after a whole number of steps of fourths or fifths, they arrive at the same position at which they began.

Go to umich.edu for mathematical comparison of LucyTuning to 1/4 comma meantone and 12tET

Meantones are usually considered to be neutral (i.e. 700 cents for the fifth in 12tET); negative (less than 700 cents), or positive (more than 700 cents).

All meantones can be notated in conventional music notation. In negative meantones (like LucyTuning) the sharp of a note will be closer to the starting note than to the Large interval above; whereas in positive meantones it will be nearer to the Larger interval above. i.e in negative meantones L< 2s; in positive meantone L> 2s and in 12tET L=2s.
