This one is very short and even elementary. It would not be worth much attention except for one important component: It includes Braj Bhasha forms right next to Hindi, so you can compare the two.

As any lover of Hindustani classical music knows, even though the lyrics are simple and repetitious, you can't understand them if you haven't studied Braj.

I have a few more materials on Braj but nothing spectacular, and there is a French grammar whose name escapes me but I would really like to have it.

Also, any Dakhni Urdu materials would be great!
