Package Exports
- helmholtz
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (helmholtz) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Parsing notes written in
Helmholtz pitch notation
returning intervals in octaves and fifths relative to A4 (or a')
var helmholtz = require('helmholtz');
helmholtz('a\'') // -> [ 0, 0 ]
helmholtz(',,C') // -> [ -3, -3 ]
helmholtz('d#\'') // -> [ -4, 6 ]
helmholtz('a\'\'') // -> [ 1, 0 ]usage
var helmholtz = require('helmholtz');helmholtz(note)
Takes a note string in the Helmholtz notation and returns an array
describing the interval of that note relative to A4. The returned interval is
in the format [octaves, fifths] - that is, an array consisting of two
numbers, the first the number of octaves to jump, the second the number of
fifths to jump from A4 to land at the desired note.
