It will be seen that two phases of memory must enter into the "memory of music"— the memory of tune and the memory of the notes. The memory of tune of course falls into the class of ear-impressions, and what has been said regarding them is also applicable to this case. The memory of notes falls into the classification of eye-impressions, and the rules of this class of memory applies in this case. As to the cultivation of the memory of tune, the principle advice to be given is that the student takes an active interest in all that pertains to the sound of music, and also takes every opportunity for listening to good music, and endeavoring to reproduce it in the imagination or memory. Endeavor to enter into the spirit of the music until it becomes a part of yourself. Rest not content with merely hearing it, but lend yourself to a feeling of its meaning. The more the music "means to you," the more easily will you remember it. The plan followed by many students, particularly those of vocal music, is to have a few bars of a piece played over to them several times, until they are able to hum it correctly; then a few more are added; and then a few more and so on. Each addition must be reviewed in connection with that which was learned before, so that the chain of association may be kept unbroken. The principle is the same as the child learning his A-B-C—he remembers "B" because it follows "A." By this constant addition of "just a little bit more," accompanied by frequent reviews, long and difficult pieces may be memorized.
