"The outpouring of a feeling toward its object, whether to the endless heavens, or forth into the boundless world, or toward a definite, limited goal, resembles the surging, the pressing onward of a flood," said the great teacher, Dr. Adolph Kullak. "Reversely, that feeling which draws its object into itself has a more tranquillizing movement, that especially when the possession of the object is assured, appeases itself in equable onward flow toward the goal of a normal state of satisfaction. The emotional life is an undulating play of up-surging and subsidence, of pressing forward beyond temporal limitations and of resigned yielding to temporal necessities. The crescendo and decrescendo are the means employed in music for the portrayal of this manifestation of emotional life."
Another important matter which may to a great extent be reduced to rule is that of accentuation. Through it a tone-picture is invested with animation, and a clue is given to the disposition of tonal forms. Accents are always required to mark the entrance of a theme, a phrase or a melody. Where there are several voices, or parts, as in a fugue, each voice denotes its appearance with an accent. Every daring assertion hazarded in music, as in speech, demands special emphasis. Dissonances need to be brought out in such prominence that they may not appear to be accidental misconceptions, and that confident expectation may be aroused of their ultimate resolution. Accentuation must be regulated by the claims of musical delivery. At all times too gentle an accent is without effect, too glaring an accent is to be condemned.
Hans von Bülow strenuously advised young musicians to cultivate their ears and strive to attain musical beauty in what is termed phrasing, which he regarded as the real beginning of greatness in a performer. Phrasing and time keeping are two of the prime essentials in musical delivery, and cannot be neglected with impunity.
Time may well be called the pulse of music. Upon some occasions the pulse beats more rapidly than others. It is incumbent on the interpreter of music to ascertain the harmonic and other causes which determine the tempo of a musical composition, as well as those which make slight variations from it admissible. Among other points to be noted is the fact that sudden transition from repose to restless activity calls for an accelerando, while the reverse requires a rallentando.
It is absolutely imperative for one who would interpret music to cultivate the memory. The musician who cannot play or sing without notes is compelled to expend a large amount of mental activity on reading these, and will find it difficult to heed the manifold requirements of musical expression and delivery, of which a few hints have here been given. A musical composition is never thoroughly understood until it has been intelligently memorized. One who can play or sing without notes is as free as a bird to soar aloft in the blue ether of musical imagination.
FRANZ LISZT
Every interpreter of music longs for appreciative listeners, and young musicians, in especial, often lament the lack of these. It is well to remember that the genuine musical artist is able to create an atmosphere whose influences may compel an average audience to sympathetic listening. A good plan for the artist is to be surrounded in fancy with an audience having sensitively attuned ears, intellectual minds, and warm, throbbing hearts. Music played in private before such an imaginary audience will gain in quality, and when repeated before an actual public will hold that public captive.
We have it from Ruskin that all fatal faults in art that might otherwise be good arise from one or other of three things: either from the pretence to feel what we do not; the indolence in exercise necessary to obtain the power of expressing the Truth; or the presumptuous insistence upon, or indulgence in, our own powers and delights, with no care or wish that they should be useful to other people, so only they should be admired by them.
