Rapping (sound)

“ Rap, rap! upon the well-worn stone How falls the polished hammer Rap, rap I the measured sound has grown A quick and merry clamor. Now shape the sole! now deftly curl The glossy vamp around it, And bless the while the bright-eyed girl Whose gentle fingers bound it! ”

“ The listener may know what syllable is meant, and overlook the defect either from habit or from an uncritical attitude, but composers of vocal music should bear such facts in mind and not impose impossibilities on singers. At the same time, the vocalist, in order to satisfy a modern audience, is obliged to sound every word and every syllable as correctly as possible, even if the tone suffer somewhat thereby. ”

“ Anyone who has noted the contrast between the harsh quality of tone emitted from childish throats when using the chest-voice, and the pure, flute-like sound produced when the head-tones are sung will agree that the last is music and the first noise, or at any rate very noisy, barbaric music. ”

“ Musical sound, or tone, is produced by regular vibrations, and differs from mere noise whose vibrations are irregular and confused. The pitch of a musical tone rises in proportion with the rapidity of the vibrations that produce it. Tones may be perceived by the human ear ranging from about sixteen vibrations in a second to nearly forty thousand, more than eleven octaves. Only about seven octaves are used in music. The science of acoustics is full of interesting facts of this kind, and is of profound value to any one who would gain an insight into the structure of music. ”

“ But, as these shorter vibrations are quicker, they yield notes of a higher pitch, which mingle with the fundamental note, and alter its quality. These accompanying higher notes may be in harmony with the fundamental note (when they are called harmonics) , or they may not harmonize with it. The sounds emitted by the parts of a vibrating body are called overtones, and it is possible for a string to furnish as many as 20 or 30 of these. The mingling of the overtones with the fundamental one determines the timbre of sound. ”

“ The resonance of the bugles and the far-reaching vibrations of the bells, with their overtones and harmonics, were specially noted by the young musician, and used by him later in his music. It is a well-known fact that every tone or sound is accompanied by a whole series of other sounds; they are the vibrations resulting from the fundamental tone. If the tone C is played in the lower octave of the piano, no less than sixteen overtones vibrate with it. ”

“ In music a beat means a regularly recurrent swelling caused by the reinforcement of a sound and this is set up by the interference of sound waves which have slightly different periods of vibration as, for instance, when two tones take place that are not quite in tune with each other. This, then, is the principle of the heterodyne, or beat, receptor. ”

“ Manufacturers have done much toward eliminating the thump of the hammers against the strings, and familiarity with the tone of the instrument has closed our ears against it to a great extent as something intrusive, but the blow which excites the string to vibration, and thus generates sound, is yet a vital factor in determining the character of pianoforte music. ”

“ The raps, instead of being sharp and short, may be dull and resemble the muffled sound of impact with some soft body: they may resemble the slight noises made by a mouse, a fret-saw, or the scratching of a finger-nail on wood or cloth: they may affect the most diverse modalities. ”

“ The presence of overtones determines the quality of the sound produced. If the string vibrates as a whole merely, the tone given out is simple, and seems dull and characterless. If, on the other hand, it vibrates in such a way that overtones are present, the tone given forth is full and rich and the sensation is pleasing. A tuning fork cannot vibrate in more than one way, and hence has no overtones, and its tone, while clear and sweet, is far less pleasing than the same note produced by a violin or piano. ”

“ With the musical sound given out by these vibrating strings must inevitably be mixed the dull and unmusical sound of the blow that set them vibrating. The trained ear will detect not only the thud of the hammer against the string, but that of the finger against the key, and that of the key itself upon its base. The study of touch and tone upon the piano is the study of the combination and the control of these two elements of sound, the one musical, the other unmusical. ”

“ Furness. Do these raps always have that vibratory sound—tr-rut—tr-rut—tr-rut?
“The ‘Medium.’ Sometimes they vary.
“Mr. Furness. As a general rule I have heard them sound so.
“The ‘Medium.’ Every rap has a different sound. For instance, when the ‘spirit’ of Mr. Seybert rapped, if the sound was a good one, you would have noticed that his rap was different from that of another. Every one is entirely different from another.
“Mr. Furness. Do you suppose that the present conditions are such that you can throw the raps to a part of the room other than that in which you are? ”

“ Yet everyone lies higher in proportion to the principal tone; the ear feels less the desire of breaking off in the pure triple sound; it is even more satisfied without it. Practised players continue to draw out the second, sometimes even the third, interval, in the higher octave. ”

“ The cure for the trouble is brought about by the introduction of materials such as carpets, tapestries, and the like, which act as absorbers of sound and reduce the time of reverberation.
When music is played in an auditorium with a prolonged reverberation, the tones following one another blend and produce the same effect as that of a piano when played with the loud pedal in use. A reverberation is more advantageous for music than for speech, since the prolongation and blending of the musical tones is desired, but the mixing of the words in a speech is a distinct disadvantage. ”

“ A teacher must see to it at first with the utmost attention that all the tones according to their pitch are struck with purity, and this can be done only by his repeating them over and over again to his pupil, because, as we have already remarked, our pianos, according to the present method of tuning, are never sufficiently pure to form a singing tone. When the learner has once become familiarized to the fine sound of pure tones, he will hear and distinguish them, and learn to strike them correctly with our pianos. ”

“ The third quality of sound is due to the form of the vibrations regardless of the pitch or the loudness. The trained ear recognizes, for instance, in the note of the tuning fork, the violin, the clarionet and the piano, the same tone howsoever made. ”

“ The only thing essential for the production of a musical sound is that the waves which reach the ear shall be rapid and regular; it is immaterial how these waves are produced. If a toothed wheel is mounted and slowly rotated, and a stiff card is held against the teeth of the wheel, a distinct tap is heard every time the card strikes the wheel. But if the wheel is rotated rapidly, the ear ceases to hear the various taps and recognizes a deep continuous musical tone. The blending of the individual taps, occurring at regular intervals, has produced a sustained musical tone. ”

“ It is not only their treatment of runs which makes it audible, nor do they depend only upon the after-sounds of notes which have been struck. Holding the dampers off the strings for relatively long spaces allows an almost distinct vibration of overtones or of sympathetic tones to enter into the mass of sound. Both Debussy and Ravel count upon this. The notes they write upon the page are but the starting point of their effects. It is what floats up and away from them that constitutes the background of their music. ”

“ To the primitive savage mind, the smallest rhythmic phrase is a wonderful invention, therefore it is repeated incessantly. Add to that a certain joy in mere sound, and we have the howl, which certainly follows the sequence of nature, for a thunder clap, or the phenomenon of echo, is its prototype, being a loud explosion followed by a more or less regular sequence of minor reverberations. When the accent of passion is added to these two principles—will and nature—we have laid the æsthetic foundation for all that we call music. ”

“ This law of sound secures the appropriate resonance for every pitch much more accurately than it could be secured by an effort to develop chest, middle, and head registers through calculating the differences. Again, we need the higher chambers of resonance to reinforce even the low pitch, because every note has its overtones that enrich it, and if these cannot find their proper resonance the tone is impoverished. ”

“ Unless you have some pointed remark to make about the rendition of the music, it is far better to give merely the place of beginning without making any remarks at all. Securing quiet by a prolonged rapping with the baton is a sign of weak discipline. Do not rap at all until the music is distributed, the accompanist in his place and ready to begin, your score open, and until you know exactly what you are going to do first. Then let just a slight tap or two suffice to notify everyone that the rehearsal is to begin at once. ”

“ At first he had appreciated only the material quality of the sounds which those instruments secreted. And it had been a source of keen pleasure when, below the narrow ribbon of the violin-part, delicate, unyielding, substantial and governing the whole, he had suddenly perceived, where it was trying to surge upwards in a flowing tide of sound, the mass of the piano-part, multiform, coherent, level, and breaking everywhere in melody like the deep blue tumult of the sea, silvered and charmed into a minor key by the moonlight. ”

“ The volume, or loudness, of a sound depends on the size of the vibrations, just as one feels a blow from a large object, other things being equal, more than from a small one. The ear drum-head is in the case of a large sound beaten, as it were, more powerfully. The singers that give us bigness of sound instead of quality belabor our ears, so to speak; they treat us as persons of mean understanding—dull intellects ”

“ Moreover, as a resonant instrument would amplify the sound and an inferior one would hamper it, so a greater artist would interpret a message to more effect than one less capable. The gramophone will give us the actual notes of the singer, but it depends upon ourselves as to whether we catch the real thing or not. ”

“ While studying beats Sauveur makes the remark that they are displeasing to the ear. He held the beats were distinctly audible only when less than six occurred in a second. Larger numbers were not distinctly perceptible and gave rise accordingly to no disturbance. He then attempts to reduce the difference between consonance and dissonance to a question of beats. Let us hear his own words. [141]
"Beats are unpleasing to the ear because of the unevenness of the sound, and it may be held with much plausibility that the reason why octaves are so pleasing is that we never hear their beats. ”

“ Within a certain restricted length of air-waves lies all of the pleasurable sensation which we call musical tone. But as we rise in the scale the tone begins to become uncertain, until the highest note of the instrument is again indefinite noise. ”

“ Other vocal sounds than sustained vowel notes are found to be due to still more complicated combinations of vibrations of shorter duration, and noises, as distinguished from musical sound, are formed also by the superposition of a greater or less number of systems of vibrations, the rapidities of which are wanting in harmonic relations such as we have pointed out belong to the musical scale. ”

“ The common musical scale is derived from a tone and its overtones, by making, on separate strings, full tones corresponding to the overtones of some fundamental string-tone. That which produces a "chord" in music, where the harmony is made by full tones, would produce a vowel if the main tone only were full, and the "chording" tones overtones. When, then, a vowel is sung, high or low, it is still the same vowel at a different pitch—that is, the same "chord" in another key. But "chords" are music, and music means air-waves, so that vowels are musical air-waves. ”

“ When, therefore, a whole tone lies below any note marked for a beat, an accidental sharp is to be supposed on that lower note, except that A is seldom thus sharpened in a beat. The beat is, therefore, the reverse of the shake, (but without the turn,) and is made generally at the distance of a semitone below ; and all the notes, excepting C and F, re-quire the note below to be sharped for the beat. ”

“ The fundamental tone was afterward raised to unison with the flame. On approaching unison beats were again heard, and the jumping of the flame proceeded with an energy greater than that observed in the case of the octave. The counter of the instrument then recorded the accurate rate of the flame’s vibration.
The tones first heard in the case of the siren are always overtones. These attain sonorous continuity sooner than the fundamental, flowing as smooth musical sounds416 while the fundamental tone is still in a state of intermittence. ”

“ With few exceptions music has been for some centuries the art which has devoted itself not to the reproduction of natural phenomena, but rather to the expression of the artist's soul, in musical sound. ”
