I grew up on Marine Corps bases and heard this special tune played daily.
I was taught from a very early age to respect the flag and the men and women in uniform who put their lives at risk, insuring our Feedom.
"Colors" is the ceremonial raising or lowering of our nation's flag. On a military base, you will typically hear some type of music during colors, perhaps the national anthem or "To the Color" while the flag is raised or lowered. If you are driving, you should stop your car until the last note sounds. If you are outside your vehicle, home or place of business, you should stop moving and stand respectfully at attention, placing your right hand over your heart and facing the direction of the main flagpole on base, until the music ends. Men and boys should remove their hats. Of course, active duty military members, veterans and Scouts in uniform should render a military salute.
