When there's music, everything becomes exciting. 
But by the time you created music, you somehow found that music is a million souls.

One study showed that children who had three years or more musical instrument training performed better than those who didn’t learn an instrument in auditory discrimination abilities and fine motor skills.

Music can be one of MaHA or MiHA to accelerate motor cortex of the brain. 
MaHA (Macro Happiness Agent)
MiHA (Micro Happiness Agent)

Awake, my soul, awake, stringed instruments, I will awaken the dawn.
