"5. Do not attempt to practice your whole piece at first. Take a small section or even a phrase. If you take a longer section than say sixteen bars, you will find it difficult to avoid mistakes. Of course, when the piece is mastered you should have all these sections so unified that you can play the entire composition smoothly and without a break.
"6. First memorize mentally the section you have selected for study, and then practice it. If you do not know it well enough to practice it from memory, you have not grasped its musical content, but are playing mechanically.
"7. Occasionally memorize backwards, that is, take the last few measures and learn them thoroughly, then take the preceding measures and continue in this way until the whole is mastered. Even after you have played the piece many times, this process often compels a concentration that is beneficial.
"8. When studying, remember that practice is simply a means of cultivating habits. If you play correctly from the start you will form good habits; if you play carelessly and faultily your playing will grow continually worse. Consequently, play so slowly and correctly from the start that you may insure the right fingering, phrasing, tone, touch (staccato, legato, portamento, etc.), pedaling and dynamic effects. If you postpone the attainment of any of these qualities to a later date they are much more difficult to acquire.
"9. Always listen while you are playing. Music is intended to be heard. If you do not listen to your own playing it is very probable that other people will not care to listen to it either.
"10. Never attempt to play anything in public that you have just finished studying. When you are through working upon a piece, put it away to be musically digested, then after some time repeat the same process, and again the third time, when your piece will, have become a part of yourself."
