For an N-ad in N voices, there are N! possible voicings, which are grouped into (N-1)! generalized voicings, which are grouped into (N-2)<sup>2</sup> + 1 stepspans.{{Navbox notation}}
For an N-ad in N voices, there are N! possible voicings, which are grouped into (N-1)! generalized voicings, which are grouped into (N-2)<sup>2</sup> + 1 stepspans. For an N-ad in M voices (M > N), use Stirling numbers of the second kind.
