Easy is the second least challenging difficulty in the Guitar Hero series, after Beginner. It only uses the green, red, and yellow fret buttons. This eliminates moving your fingers up and down the frets completely. The fret board also moves very slowly in easy. This is the difficulty that most new Guitar Hero players start on, and people who play Expert might have a hard time because they aren't used to it, seeing how hard and expert difficulties require rapid hand movement and finger dexterity, easy requires more precision due to it being so much slower. This is why some more experienced players choose to use hyperspeed to full combo songs on easy.
