>>>To install locally:

To run the tests:
$ python tests.py
Melopy is broken down into 3 subcategories - melopy, scales, and utility.
melopy.pycontains the Melopy class- this is used for creating a Melopy and adding notes to it, rendering, etc
scales.pycontains methods for generating scales- for instance, if you want to store the C major scale in an array
utility.pycontains methods for finding frequencies of notes, etc
>>> from melopy import Melopy
>>> m = Melopy('mysong')
>>> m.add_quarter_note('A4')
>>> m.add_quarter_note('C#5')
>>> m.add_quarter_note('E5')
>>> m.render()
