I call it enchantment... and I think music has as much to do with magic, as (example) martial arts has to do with magic. You can use it for only exercise, or performance, but that's just going through the movement. Only when you align your mind to the action does it become effectively magical.
First, listening to music... you might notice that a song with a lot of minor chords sounds sad, or a song with a high tempo sounds exciting. Like Yue said, music influences your mood-- you might not want a solemn song playing while you cast a happiness spell, because your spirit is affected by the mood.
Next, actually using music... simplest way is to sing. But, that takes a lot of confidence, just like practicing magic since the knee-jerk reaction from most people about both is "You can't do that."
Your chest and skull are a potential sound chamber-- their shape and size resonates to a certain musical note. When you hum this note, your entire body turns into a musical instrument, it will tremble to the tips of your fingers. Ceremonial magicians call this "vibration", and from a psionic view this could be the physical equivalent of giving off "vibes".
With using the words and melody of music, the simplest example is the mantra. I was taught that the syllable "OM" or "Aum" has a special function in aligning the spirit. "A" vibrates your feet and legs while you sit in lotus position. "U" sends tremors in your chest. "M" makes your skull vibrate. It builds the proper foundations, much like channeling the power vortexes in your body (your chakras) from the bottom to the top.
Another example of using sound: some chaos magicians banish by laughing. Depending on the paradigm, they either send out blasts of psychic energy, or cleanse their minds with whatever they want to banish (when they laugh and they really mean it, there's no room in their mind for bad thought-forms anymore.)
Some cultures used drumming to induce a trance. Wiccan spells bind with rhyme, I think it's because rhyme usually comes with a rhythm that does the same thing (bring on a trance.)
Based on that, you have a lot to draw from to make your own form of enchantment.
this reminds me of the time my friend was singing raindrops at the festival and when she started it started to rain and when she stoped the rain stoped. I think she knows some sound spells but she never really told me how it happened.
If you want to understand magical music research the Dead. Their music changes the people who it reaches and those people try to change the world by the way they live.
Fire on the Mountain............
Long distance runner, what you standin' there for?
Get up, get out, get out of the door
Your playin' cold music on the barroom floor
Drowned in your laughter and dead to the core.
There's a dragon with matches that's loose on the town
Takes a whole pail of water just to cool him down.
Fire! Fire on the mountain!
Almost ablaze still you don't feel the heat
It takes all you got just to stay on the beat.
You say it's a livin', we all gotta eat
But you're here alone, there's no one to compete.
If Mercy's a bus'ness, I wish it for you
More than just ashes when your dreams come true.
Fire! Fire on the mountain!
Long distance runner, what you holdin' out for?
Caught in slow motion in a dash for the door.
The flame from your stage has now spread to the floor
You gave all you had. Why you wanna give more?
The more that you give, the more it will take
To the thin line beyond which you really can't fake.
ok how come that made me cry?
i dunno but i cld feel the power in it
i get wat they say about vibes and vibrations i can kinda do the same with humming since i cant sing that well i can even do it with beat thing of what u wish or will to happen then let the beat or hum take over
