An instrument is what houses and conforms the sounds that come out.
Notes that are not in tune with one another will sound less than pleasing bringing a cringe.
Notes that are conformed in a rhythmical balanced they will bring a smile, a sway that is so soothing and pleasing.
This is the mind and body being in harmony! This is a body that can refresh and recover quickly.
Live in the awareness of whether your mind and body are singing the same tune, it will serve you well.
In appreciation of you,
