Music is the way of expression. Music is a feeling. Music means different to different people.. for some it is the expression of joy, for some it is the expression of grief, for some it is the expression of excitement, celebration, etc. The word in itself is so powerful that it creates positivity, generates enthusiasm in the mind. Music is the air and water to mind just like air and water to a living being.
Music is just like beauty. As beauty lies in the eye of beholder, so is music to a listener :)
Many might like the rhythm created by tinkering of a tin or sound coming out of wheels of a running train or beating drums or beating stones rhythmically. Music can be felt in instruments, words, rhythm, humming, chirping birds, stridulating grasshoppers or crickets, swaying branches of a tree on a windy day.
Music is the global language without a lingo sans any control, geographical borders and universally loved by all. Even an unborn gets the impact of music, animals and trees too ain't uneffected from this magic.
A symphony created by all time greats like Beethoven, Mozart. Looking back at Indian mythology, Lord Krishna was a great flutist. He used to control his herd of cows by playing his flute. The great musician in early 16th century Tansen in Emperor Akbar's court, has the command on music so much so that he was able to attract the rains. Indian Maestros like Ravishanker, Zakir Hussain, Amjad Ali Khan, Bismillah Khan, Lata Mageshkar, have global fan-following although most of them have been playing instruments which does not have any language known to a common man.
Nothing comes without practice. All these greats have devoted their life to music by non-stop practicing for hours and hours. They live with passion towards music.
