Raag Megh | Seventh Prahar / Any time in Monsoon | Bandish | Ghanan Ghanan Ghan Ghor

Megh is a Hindustani classical raga. The meaning of Megh in Sanskrit is 'Cloud'. Hence this raga is mostly sung or played in the Monsoon season. Another raga which describes rain is raga Malhar. So these 2 ragas were merged and a new raga was developed, this raga is raga Megh Malhar.
This is one of the very old ragas found in Indian classical music. This raga is related from Lord Krishna time period, when Govardhan Parvat (mountain) was on Lord Krishna's short finger during the Govardhan leela, then Lord Shiva generated a Damru sound to protect Lord Krishna. That sound which was generated by the Damru was raga MEGH....
There is legend stating that Tansen's physical agony after singing Raga Deepak (Poorvi Thaat) was pacified with listening to Raga Megh Malhar rendered by two sisters, Tana and Riri.
