Hanon Exercise 51

The wrists should be very supple, the fingers taking the octaves should be held firmly but without stiffness, and the unoccupied fingers should assume a slightly rounded position. At first repeat these three first lines slowly until a good wrist movement is attained, and then accelerate the tempo, continuing the exercise without interruption. If the wrists become fatigued, play more slowly until the feeling of fatigue has disappeared, and then gradually accelerate up to the first tempo.

Begin with the metronome set at 40, gradually increasing the speed up to 84.
