Math and Music are essentially the same. Music has a physical manifestation.

So listening to good Music trains your mind to focus and remember the lyrics. 

Math helps you describe natural phenomenon and quantify them.

Music describes emotions that are abstract, but they can be felt by living beings.

Singing improves your health and wellbeing. 

Just remember to keep the volume and time within limits. Tune out and focus on your tasks after few minutes. 

Melodious music helps relax. So it is pure Magic when certain musical patterns are recreated.

Tribute: My Heartiest Wishes to John Williams on his 93rd Birthday.  May the music heal the scars of fire. Let peace prevail.
