d'accord

> D'accord, je vais analyser vos accords

A simple module for parsing chord symbols, both Jazz and Classical.
Parses correctly everything from simple power chords (D#5) to chords you'll
often find in the real book (G7#5, Dm7b5) to crazy chords like
Fsus4maj#11 or Cm13b5#9.

Note that this module only parses the chord symbol (that is the part of the
chord string that does not include the root, and thus returns relative
intervals from which the chord can be constructed with any root.

example

``js
var daccord = require('daccord');

daccord('m7b5') // -> ['P1', 'm3', 'd5', 'm7']

daccord('maj7') // -> ['P1', 'M3', 'P5', 'M7']
`

You can use d'accord in combination with
teoria.
Although at the moment teoria includes this functionality itself this will
hopefully get lifted out of teoria into more focused, smaller modules. But for
now, here's a practical example

`js
var daccord = require('daccord');
var teoria = require('teoria');

// Create the root note
var root = teoria.note('C4');

// Get all the intervals (including the tonic) of a m(maj7) chord, and map them
// into notes relative to the root, C4
daccord('m(maj7)').map(root.interval.bind(root)).toString() === 'c4,eb4,g4,b4';
`

usage

`js
var daccord = require('daccord');
`

$3

Return an array of intervals (including the tonic, that is P1), which
constitutes the full chord, with all implied intervals.

If a chordstring is unparsable, an error will be thrown with details:
`js
// ParseError:
{
message: String, // The full error message
title: String, // The error title
token: String, // The erronous token
index: Number // The index of the token in the chordstring
}
