You should not try to study all of one volume in one practice period.? Split each lesson up into easily managed sections and make a point of learning one section at a time.? Learn that section well before proceeding to the next section.?
The main thing is to be so familiar with the various points contained in each lesson that you can readily turn back to any point for reference.? Make sure that you do refer back as hazy half conceptions can create difficulties in the future.?
Take full advantage of your course by reading each lesson through so that you get an overview of the contents, then go back and study it thoroughly in sections, then go back again and study it in depth with actual practice.? Certain paragraph and entire pages may require more concentrated study and frequent reading helps tie things together.?
How is your latest piece going?? Can you play well enough for your family and friends to listen to it?? If you can then pat yourself on the back as you are making good progress.? If not, don't worry about it as some people are slower than others.? Whatever your progress you can rest assured that with practice you will improve.? You are at the beginning and if you continue to practice regularly and study carefully you will improve and derive great satisfaction and enjoyment.? When you have completed your course you will have gained a good knowledge of music and will be able to play in a way that can bring you many opportunities.
