Flute is a divine instrument of music. Scriptures of India reveal its enchanting influence on all the animate and inanimate objects when Lord Krishna played it on the banks of the river Yomuna. Shehnai also belongs to the same genre of musical instruments. In fact, both the Sushir Vadyas (the instruments played with blowing air into them) cast their supernatural impact upon the listeners. And, despite this spellbinding effect, both flute and Shehnai don't have much complexities in their playing.
