The memory of notes may be developed by the method above named—the method of learning a few bars well, and then adding a few more, and frequently reviewing as far as you have learned, forging the links of association as you go along, by frequent practice. The method being entirely that of eye-impression and subject to its rules, you must observe the idea of visualization—that is learning each bar until you can see it "in your mind's eye" as you proceed. But in this, as in many other eye-impressions, you will find that you will be greatly aided by your memory of the sound of the notes, in addition to their appearance. Try to associate the two as much as possible, so that when you see a note, you will hear the sound of it, and when you hear a note sounded, you will see it as it appears on the score. This combining of the impressions of both sight and sound will give you the benefit of the double sense impression, which results in doubling your memory efficiency. In addition to visualizing the notes themselves, the student should add the appearance of the various symbols denoting the key, the time, the movement, expression, etc., so that he may hum the air from the visualized notes, with expression and with correct interpretation. Changes of key, time or movement should be carefully noted in the memorization of the notes. And above everything else, memorize the feeling of that particular portion of the score, that you may not only see and hear, but also feel that which you are recalling.

We would advise the student to practice memorizing simple songs at first, for various reasons. One of these reasons is that these songs lend themselves readily to memorizing, and the chain of easy association is usually maintained throughout.

In this phase of memory, as in all others, we add the advice to: Take interest; bestow Attention; and Practice and Exercise as often as possible. You may have tired of these words—but they constitute the main principles of the development of a retentive memory. Things must be impressed upon the memory, before they may be recalled. This should be remembered in every consideration of the subject.
