Watch the Hindustani Vamp online guitar lesson by Fareed Haque from Jazz Rock Workshop

Creating a drone is important for an Indian sound. Tonic, of course, is the most important note in your drone, which can sometimes can be strengthened by adding a 5th above the root.

If you want that true Indian drone, you need a Tampura, a long sitar-like instrument, usually strummed during a performance by a student or disciple of the performing musicians.

Another traditional, sound. It's electronic, and some have a line out, others a little speaker you can mic. The sound is rich and perfect for creating that South Asian sound. Make sure to use plenty of reverb.
