JavaScript How to build a Collection/Model from nested JSON with Backbone.js

I'm at work, so I cannot give you a fully coded answer, but the gist is, you can do the following in your top level models to achieve a nested model hierarchy:

var AmericasNextTopModel = Backbone.Models.extend({
    initialize: function(){

        this.set({
             clefs: new ClefCollection(this.get('clefs')),
             accidentals: new AccidentalCollection(this.get('accidentals')),
             notes: new NoteCollection(this.get('notes')),
             rests: new RestCollection(this.get('rests'))
        });
    }
});

I do not use backbone-relational so I cannot give you an answer regarding that.

Are you making an online sheet music viewer/editor? :D Cool I'd love to see it when you're done.

The reset method (see 'reset') allows you to pass a JSON array to a collection. This is the equivalent of a PUT method, replacing the specified collection with the JSON hash.

You can also use the add method to add to an existing collection, or pass the JSON hash into the constructor as you create a new collection.

You'll have to do some basic cleaning up of your array to get it in an appropriate format, and then convert it to JSON
