A number of shots fired at a given range at one target & with one sight setting, with either rifle or handgun, to determine the accuracy of either the gun or the ammunition. With a handgun the most common range is probably 25 yards. A two inch group is generally considered good.
Stevie Wonder plays a Hohner Chromatic Harmonica. He mostly plays the Super 64x chromatic which i recentally bought and it is amazing. The quality of sound of smoothness is incredible. I would recommend it to anyone playing the harmonica.
Most kinds of American folk, pop, blues, or rock music use a simple 10-hole harmonica, like the Marine Band that Hohner is known for. But the same harmonica can be used entirely differently by two different players. Traditional harmonica players play songs in the key that the harmonica is labeled for.
