An harmonizer is a function that receives a note and return an array of notes:

```js

var harmonizer = require('music.harmonizer')

var maj7 = harmonizer('1 3 5 7')

maj7('D') // => ['D', 'F#', 'A', 'C#']

dorian = harmonizer('D E F G A B C')

dorian('C') // => ['C', 'D', 'Eb', 'F', 'G' 'A', 'Bb']

```

## Install

Currently only via npm: `npm i --save music.harmonizer`

## Usage

#### Create an harmonizer from a list of intervals

```js

// intervals using number and quality

var majorTriad = harmonizer('1P 3M 5P')

majorTriad('Eb') // => ['Eb', 'G', 'Bb']

// intervals using number and alteration

var minorTriad = harmonizer('1 3b 5')

minorTriad('F') // => ['F', 'Ab', 'C']

```

Take a look to [music.interval.parser](https://github.com/danigb/music.interval.parser) to see the intervals format.

### Create an harmonizer from a list of notes. 

If you give a list of notes, `harmonizer` function will calculate the intervals from the first note of the list to the rest:

```js

var maj7drop2 = harmonizer('C2 E2 G1 B2')

maj7drop2('A2') // => ['A2', 'C#3', 'E2', 'G#3']

```

#### Get harmonizer intervals

Finally, you can get the intervals with the tonic equal `false`:

```js

harmonizer('C D E F G', false) // => ['1P', '2M', '3M', '4P', '5P']

```
