An app made by two friends of mine – one is a Vedic astrologer named Rok. It is FANTASTIC whenever you want background music. You can select a main instrument, a drone instrument, and an ambient background, as well as a timer instrument. It will use these settings to play in the RAGA appropriate for your local time of day! The timer makes it extremely useful for yoga-āsana classes. Here is the link: http://bit.ly/3No9mDt
