According to my Guitar Atlas Series book on Indian Music, the classical system of Indian music is over 3000 years old. The book has the sheet music for a few of those ancient songs.
I took said sheet music from the book and mixed all of the songs together. In order of appearance, here are the titles:
1. Come Let us Go to Assam
2. Let Me See You Dance in the Moonlight
3. Folksong from Rajasthan
4. Praise Be The Almighty
5. Glory to The Lord
6. Qawwali Tune
