isnext v0.0.3

isnext

isnext is factored out of whatnext.sf. It is a simple chord analysis tool built off of teoria.js. Given a chord progression, it tries to guess the labeling of the chords

var isnext = require("isnext");
var labelings = isnext.label_progression("a d a d f g a");
var probable = labelings[0];

// Is a dictionary of possible chord modulations / follow ups
var variations = isnext.get_variations(probable);
