My notation may differ from conventional xen notation, especially in more technical xen theory writings.

Variables

  • Capital italicized Latin letters may denote scales written cumulatively.
    • S(n) = 100n cents
  • Lowercase italicized Latin letters may denote scales written as steps or abstract scale words. For example:
    • s(a, b, c) = abacaba
    • [math]\displaystyle{ \sum_{n=a}^{b-1}s(n) = S(b)-S(a) \ \text{if} \ s(n) := S(n+1)-S(n) }[/math]
  • Bolded variables denote interval sizes, especially letters of scale words.
    • 5L 2s
  • Sans serif function names are scale constructions, or more generally functions named more verbosely than in conventional math notation.
    • [math]\displaystyle{ \mathsf{MOS}(5,2;6)(\mathbf{L}, \mathbf{s}) = \mathbf{LLLsLLs} }[/math]

Algebraic structures

  • [math]\displaystyle{ \mathrm{JI}\langle p_1, ..., p_r \rangle }[/math] is the p1.[...].pr subgroup, the subgroup of [math]\displaystyle{ (\mathbb{Q}_{\gt 0}, \cdot) }[/math] generated by rationals [math]\displaystyle{ p_1, ..., p_r. }[/math]
  • If R is a commutative ring, [math]\displaystyle{ R^r\langle a_1, ..., a_r\rangle }[/math] is the rank-r free R-module generated by basis elements [math]\displaystyle{ a_1, ..., a_r. }[/math] Example: [math]\displaystyle{ \mathbb{Z}^3\langle \mathbf{L}, \mathbf{m}, \mathbf{s}\rangle }[/math]
