It is a very interesting question. I really want to know what the effects sound and music on plant. I know that classical music effects on dairy cattles, but I dont know the effect on plants
In Iran, I had a research about this field, the result shown that when we play the classic music for Chrysanthemum, it has highest level of performance (wet weight and number of flower) in comparison of other music type. but this result change in cactus plant, such that the cactus plant shown positive reaction to trance music.
This investigation carried out at Central research of Mahalat, Iran. I hope it use full for you dear Ali but if you want to focus on this field I think if you test the different word to assessment of plant reaction is better than music because that is more accurate (Different word test). You can get Professor Masaro-Imuto's project which name is WATER TESTIFIED from internet.
God bless you
As you probably know, sound is a wave, and more specifically, a pulse wave. This simply means that it is formed by areas of higher and lower pressure in the atmosphere through which it travels. Terms such as "amplitude," when used in reference to sound, are actually referring to the plot of the air pressure versus time on a graph. Now, it is difficult to believe that such (extremely small) fluctuations in air pressure could have any effect on a plant's growth. There is very little difference, to a plant, in music and ambient noise.
However, you might want to consider this question from another perspective. It is possible that in an experiment, plants which are exposed to music may grow more than plants that are not. Why? Because even though it is unlikely that the plants themselves respond to the music, their /caretakers/ do! Maybe the plants which are exposed to music receive better care than those which do not. Might be worth looking into!
I enjoyed Frank Telewski's handling of this question in his big review paper https://www.researchgate.net/publication/51192381_A_unified_hypothesis_of_mechanoperception_in_plants.
He writes, "The perception and response of plants to sound, more specifically music, has been a part of folklore and the source of inspiration for countless primary and secondary school student science fair projects beginning in the 1940s."
As to the latter, I dug back in the memory banks and came up with the 1994 response by Ross Koning, a professor who has been asked this question many times and hopes he has answered definitively.

Article A unified hypothesis of mechanoperception in plants
The changes in the growth of the plants were monitored every two days for twenty-eight days. Upon completion of the tests, it was observed that optimum plant growth occurred when the plant was exposed to pure tones in which the wavelength coincided with the average of major leaf dimensions. It is suggested that this was due to the “scrubbing” action of the traversing wave,causing air particle motion on the surface of the leaf; this movement removed the stagnant air layer adjacent o the leaf, thus increasing the transpiration of the plant. It was also noted that the plant growth was less
when exposed to random noise.
It has been reported that music will increase plant growth, but it is not known what preferred frequencies (if any) in the music have the most pronounced effect on plant
growth. Many of the papers (see above) had very little detail about the conditions under which the plants were grown,how conditions were controlled [or if they even were controlled],and exactly how the growth rates were monitored.
It was seen that the “music” plants sprouted faster, were greener, and their stems
were thicker and tougher than the “silent” plants. Although the results were interesting, this article is not scientifically grounded.
Music can greatly influence the growth of plants. In the present paper, the effect of music was studied on the growth of the selected plant – Mung (Phaseolus aureus) and it was found that seed germination as well as growth of the plant was enhanced as compared to control set. Two sets were selected – one treated with piece of music and second set untreated i.e. control. Amongst the two set, music treated plants shown better performance in terms of the seed germination and growth of plant. Number of seeds germinated, root length, plant height, number of leaves, leaf size was found to be more for the plants subjected to music and less for the control set.
