I now come to Octave Technique for which every sort of studies have been and continue to be written. Now the real octave wrist, combining great strength with high nervous tension and suppleness, is a gift of nature, like the capacity for playing staccato bowing on the violin. But those who do not possess the power can develop it to a limited extent. There are several methods of playing octaves, one being with a loose wrist and the 5th finger slightly stiffened. This is a good way for octaves in a slow tempo, but when speed is required it can only be secured by nervous contraction of the arm, the wrist being kept stiff meanwhile. To accomplish this needs much muscular strength, as the advantage of the loose wrist has to be discarded, and whenever the rapidity of the tempo increases, the stiffening of the wrist must increase also.
As far as the practice of octaves go, I do not think merely playing them in scales is efficacious, and, as I have already said, there are so many studies devised on this most difficult branch of piano technique that it is best to work with them. Those of Kullak are, I find, especially excellent. It is very unwise ever to work at octave playing for more than ten minutes at a time, as it is so fatiguing and may injure the arm if overdone. But there are ways of helping oneself to relieve exhaustion during long sequences of octaves. Some of these devices are useful for all, though generally each player finds out means for himself according to the structure of his own particular muscles.
To illustrate what I mean by these helps against fatigue, I will give an example from the A flat Polonaise of Chopin. The great octave passage in the second part for the left hand lasts 34 bars, which is a tremendous length, as all pianists know, and the strain may become almost unbearable.

Here it is a considerable relief to think of the passage as in a semi-circular motion from left to right.

group of four Octaves as component parts of half a circle.
Again, in the enormously difficult octave passage for the right hand in the Sixth Rhapsody of Liszt, it will be found to be of assistance to keep changing the position of the wrist from being high to becoming low.

This very small action of the wrist gives respite for a second from the tension, and sets the momentum of the nervous contraction going again.

This same movement can apply to most continuous octave sequences of any length, provided they are in scale-like progressions, or in the form of reiteration. But for octaves which move in arpeggi, this same action would not answer, because here the mind has to be occupied with the matter of judging the distances, or I should rather say, feeling them. For all jumps are very uncertain quantities, and no eye judgment can be possible where a high rate of speed has to be obtained. Therefore in arpeggio-like octave passages only a mental device will be of any help in the difficulty. This contrivance is to imagine the octaves in groups of threes in the mind, no matter what the rhythm is in which they are written. I take an example out of the Hungarian Fantasie of Liszt for piano and orchestra to show the idea.
