Well, the music is just a list of sound with different frequency.

With those different frequency and pause interval, the music will work like a magic to heal people's mind.

## A small protocol to represent music

People already uses numbers to represent different frequency of sound. For example, [1,2,3,4,5,6,7], 7 frequency can be written as 7 numbers.

Based on that, I suggest '-7' means 'lower 1 level 7', '+1' means 'higher 1 level 1', '--7' means 'lower 2 level 7'. And use '(0.5)' to represent pause time interval, the float number inside '()' is seconds. And use '[0.2]' to represent how long a sound note should remain or keep.

And for multiple_sound that should play togather at the same time, we use '+1_+2 +1_+2 +2_+3 +2_+3 +3_+4'.

So in the end a music can be written as:

```
# There has more pause interval between music notes, but I choose to not show them in here to simplify things.

1[0.2]1[0.2]1[0.2](1.0)

1155 665 4433 221 (1.0)
5544 332 5544 332
```
