Bhatkhande Notation Canvas

This is an Clojurescript library that can display sargam-spec format annotated Hindustani classical music compositions in an HTML5 canvas.

Here's an example of a part:

{
	"m-noteseq": [
		[{
			"note": ["madhyam", "s"]
		}],
		[{
			"note": ["madhyam", "r"]
		}],
		[{
			"note": ["mandra", "-n"]
		}],
		[{
			"note": ["madhyam", "r"],
			"kan": ["madhyam", "-g"]
		}],
		[{
				"note": ["mandra", "n"]
			},
			{
				"note": ["madhyam", "s"]
			},
			{
				"note": ["madhyam", "g"]
			},
			{
				"note": ["madhyam", "m"]
			}
		],
		[{
			"note": ["madhyam", "g"]
		}],
		[{
			"note": ["madhyam", "m"]
		}],
		[{
				"note": ["madhyam", "r"]
			},
			{
				"note": ["madhyam", "r"]
			}
		],

		[{
			"note": ["madhyam", "s"]
		}]
	],

	"taal": {
		"num-beats": 10,
		"taal-name": "jhaptaal",
		"taal-label": "\u091d\u092a\u0924\u093e\u0932",
		"sam-khaali": {
			"1": "x",
			"3": "2",
			"8": "4",
			"6": "o"
		},
		"bhaags": [2, 3, 2, 3]
	},
	"part-label": "\u0938\u094d\u0925\u093e\u0907"
}

And the output is:
