What great artists and writers say about music:

James Brown: "Music has
to breathe and sweat. You have to play it live."
Elvis Presley: "Music should be something that makes you gotta move, inside
or outside."
Oliver Wendell Holmes, Sr.: "Take a music bath once or twice a week for
a few seasons, and you will find that it is to the soul what the water-bath
is to the body."
Plato: "Music is a more potent instrument than any other for education,
because rhythm and harmony find their way into the inward places of the
soul."
Martin Luther: "Whoever has skill in music is of good temperament and fitted
for all things. We must teach music in schools."
Molière: "All the ills of mankind, all the tragic misfortunes that
fill our history books, all the political blunders, all the failures of
the great leaders have arisen merely from a lack of skill in dancing."
Fred Rogers: "Music is the one art we all have inside. We may not be able
to play an instrument, but we can sing along or clap or tap our feet. Have
you ever seen a baby bouncing up and down in the crib in time to some music?
When you think of it, some of that baby's first messages from his or her
parents may have been lullabies, or at least the music of their speaking
voices. All of us have had the experience of hearing a tune from childhood
and having that melody evoke a memory or a feeling. The music we hear early
on tends to stay with us all our lives."
Hazrat Inayat Khan (1882-1927) Founder of the Sufi Order in the West: "According
to the thinkers of the East, there are five different intoxications: of
beauty, youth and strength; then the intoxication of wealth; the third is
power, command, the power of ruling; and there is the fourth intoxication,
which is the intoxication of learning, of knowledge. But all these four
intoxications fade away just like stars before the sun in the presence of
the intoxication of music. The reason is that it touches that deepest part
of man’s being. Music reaches farther than any other impression from the
external world can reach. And the beauty of music is that it is both the
source of creation and the means of absorbing it. In other words, by music
was the world created, and by music it is withdrawn again into the source
which has created it."
