In short, finger exercises, like scales and arpeggios, are important building blocks of musicianship. Moreover, finger exercises, similar to strength training for athletes, can improve finger strength, flexibility, dexterity, and coordination these things can then improve speed, musicality, and overall performance when you are playing musical works. To learn to use the arms, hands, fingers, and wrists correctly, finger exercises are more effective than actual pieces, since exercises are often designed to target one technique and their simple structure is less distracting. Playing the piano uses more than just the fingers instead, the whole arms are required. You might ask, why should I do finger exercises? Like athletes, musicians need good control of their muscles, and strong muscles can prevent injury.
