Melody is the battle-cry of amateurs, and certainly music without melody is nothing. Understand, however, what these persons mean by it: a simple, flowing and pleasing rhythmical tune; this is enough to satisfy them. There are, however, others of a different sort, and whenever you open Bach, Mozart, Beethoven, or any real master, their melodies meet you in a thousand different shapes. I trust you will soon be tired of the inferior melodies, especially those out of the new Italian operas; and of all vulgar ones.
If, while at the piano, you attempt to form little melodies, that is very well; but if they come into your mind of themselves, when you are not practising, you may be still more pleased; for the internal organ of music is then roused in you. The fingers must do what the head desires; not the contrary.
If you begin to compose, work it out in your head. Do not try a piece on your instrument, except when you have fully conceived it. If your music came from your heart and soul, and did you feel it yourself,—it will operate on others in the same manner.
If Heaven has bestowed on you a fine imagination, you will often be seated at your piano in solitary hours, as if attached to it; you will desire to express the feelings of your heart in harmony, and the more clouded the sphere of harmony may perhaps be to you, the more mysteriously you will feel as if drawn into magic circles. In youth these may be your happiest hours. Beware, however, of abandoning yourself too often to the influence of a talent that induces you to lavish powers and time, as it were, upon phantoms. Mastery over the forms of composition and a clear expression of your ideas can only be attained by constant writing. Write, therefore, more than you improvise.
Acquire an early knowledge of the art of conducting music. Observe often the best conductors, and conduct along with them in your mind. This will give you clearness of perception and make you accurate.
