Megh Malhar is a Hindustani classical raga. The name derives from the Sanskrit word Megh, meaning cloud. Legends say that this raga has the power to bring out rains in the area where it is sung.
It has been heard that Tansen had the power to light up fire through his song called Raag Deepak and he had taught his Daughter to bring rain by singing the Meg Malhar.

Sound is a mechanical wave that is an oscillation of pressure transmitted through some medium (like air or water), composed of frequencies within the range of hearing.


Is it true or Do you believe that singing Meg Malhar and Deepak ragas can lead to raining and starting fire respectively ?.

Awaiting your reply,

Thanks & Regards,

ANSWER: > Do you believe that singing Meg Malhar and Deepak ragas can lead to raining and starting fire respectively?

The amount of energy released in the sound of a human singing is far below that necessary to do either. And, no, there is NOT a resonance frequency of an object or of a cloud that would result in creating rain or fire by singing at that frequency.

QUESTION: Dear Expert

Thank you.

Experiments can be performed in this cases.
-------------------------------------------

Aim : Check whether fire can lit up in oil lamps by singing Deepak Raag from Hindustani classical music.

Apparatus : Oil Lamps, Cotton.

Procedure : 50 Singers will sing the Deepak Raag indoors with every singer singing the Deepak raag for 1/2 hour interval.

Findings / Observation : 1. The Oil Lamps are lit up. 2. The Oil Lamps are not lit up. Either of the Case 1 or Case 2 will be observed.

Conclusion :

Case 1 :

If the Oil lamps are lit up with fire, we can conclude that SPECIFIC Sound Waves (Deepak Raag)  can generate Fire in the Oil Lamp.

Case 2 :

2. If the Oil lamps do not lit up with fire, we can conclude that SPECIFIC Sound Waves (Deepak Raag)  cannot generate Fire in the Oil Lamp.

----------------------------------------------------------------------------

Aim : Check whether rain happens by singing Meg Malhar / Malhar Raag from Hindustani classical music. Weather forecasting conditions indicate clear skies and there will be no rain for another two months. This test can be carried in summer season.

Apparatus : NA

Procedure : 50 Singers will sing the Meg Malhar Raag outdoors with every singer singing the Meg Malhar raag for 1/2 hour interval.

Findings / Observation : 1. Rain happens. 2. Rain do not happen. Either of the Case 1 or Case 2 will be observed.

Conclusion :

Case 1 :

If Rain happens, we can conclude that SPECIFIC Sound Waves
(Meg Malhar Raag)  can generate Rain.

Case 2 :

2. If Rain do not happen, we can conclude that SPECIFIC Sound Waves
(Meg Malhar)  cannot generate Rain.


Summary : Specific sound waves can produce fire or rain if the experiments are successful.

Answer
One thing you MUST do in experiment #1 is ensure that nobody is lighting the lamps. Trickery is one of the oldest problems in scientific investigation, and it continues today. Unless every possibility of lighting the lamps aside from the singing of the songs is accounted for, the experiment is not complete. Note that lamps can be made to light from far away, and even on a time delay, so even separating everyone from the lamps is NOT enough. I'm know nothing about the chemistry of lighting oil, so this is all the help I can give.

The problem with experiment #2 is that you have to eliminate the possibility that rain would have occurred even without the music being sung. If you sing a Meg Malhar song, or a song by RLC66, or ANY song at all; during the monsoon season, you might well get rain while the song is being sung. Of course, you might well get rain whether or not you sang any song at all.  You'll have to do a series of controls -- alternate days with songs and days with no songs, and sing the songs at the same time every day. Only if the singing results in rain every time, and going without songs results in no rain every time; and this repeats itself for several days; can one make any conclusion about the effect of the songs on rain.

This is all I choose to say on this matter.

I can help with understanding physics that does not involve eggs. I will NOT help with academic or professional questions, which are NOT limited only to homework. Please do not waste your time by asking a question that comes out of ANY kind of academic, professional, or business matters.

Experience

Have been fascinated by physical laws ever since I learned, at age seven, that magnets work under water. My study continued through college and has not ceased even after I retired.
