give a quote that relates to music adjusts our moods and explain it
'And those who were seen dancing were thought to be insane by those who could not hear the music' - Friedrich Nietzsche (I would have thought this quote is pretty self explanatory, but you could talk about the impact music has on our bodies- you just have to DANCE when you hear your favourite song!)
'If music be the food of love, play on' - William Shakespeare (This phrase comes from Shakespeare's Twelfth Night. Duke Orsino is upset that his courtship for the dear Olivia is not going well and asks for an abundance of love so that he will lose his appetite for it.)
And then, just some inspirational music quotes:
'Music expresses that which cannot be said and on which it is impossible to be silent.'
'It is cruel, you know, that music should be so beautiful. It has the beauty of loneliness of pain: of strength and freedom. The beauty of disappointment and never-satisfied love. The cruel beauty of nature and everlasting beauty of monotony.'
'Every song ends but is that any reason not to enjoy the music?'
Many people would probably think of the quote "Music hath charms to soothe the savage breast, to soften rocks, and bend a knotted oak" (Quote credited to William Congreve according to WikiAnswers.). I think that you can figure out the rest as to how to explain the quote. How does music make you feel when you are sad? Excited? Can music be calming to someone who is angry? Does music make one feel peaceful?
"Music is what feelings sound like" - This expresses that music isn't just another sound like traffic, or a door closing but the emphasize in the way the music is being played reflects who we are.
For example listening to acoustic is never a heavy sound and therefore it's calm and relaxing. When we are angry we listen to something with a heavy line that expresses what we feel or cannot say.
