2L 7s, also called balzano, is a moment of symmetry scale consisting of 2 large steps and 7 small steps, repeating every octave. This scale is made using a generator ranging from 533.333¢ to 600¢, or from 600¢ to 666.667¢.

Names

This scale is called balzano in TAMNAMS nomenclature.

Intervals

Note: In TAMNAMS, a k-step interval class in balzano may be called a "k-step", "k-mosstep", or "k-balstep" (/bæl-/). 1-indexed terms such as "mos(k+1)th" are discouraged for non-diatonic mosses.
