But though every sort of step, gesture, or motion, even though performed to the time and measure of Music, will not alone make a Dance, yet almost any sort of sound, provided it is repeated with a distinct rhythmus, or according to a distinct time and measure, though without any variation as to gravity or acuteness, will make a sort of Music, no doubt indeed, an imperfect one. Drums, cymbals, and, so far as I have observed, all other instruments of percussion, have only one note; this note, however, when repeated with a certain rhythmus, or according to a certain time and measure, and sometimes, in order to mark more distinctly that time and measure, with some little variation as to loudness and lowness, though without any as to acuteness and gravity, does certainly make a sort of Music, which is frequently far from being disagreeable, and which even sometimes produces considerable effects. The simple note of such instruments, it is true, is generally a very clear, or what is called a melodious, sound. It does not however seem indispensably necessary that it should be so. The sound of the muffled drum, when it beats the dead march, is far from being either clear or melodious, and yet it certainly produces a species of Music which is sometimes affecting. Even in the performance of the most humble of all artists, of the man who drums upon the table with his fingers, we may sometimes distinguish the measure, and perhaps a little of the humour, of some favourite song; and we must allow that even he makes some sort of Music. Without a proper step and motion, the observation of tune alone will not make a Dance; time alone, without tune, will make some sort of Music.
That exact observation of tune, or of the proper intervals of gravity and acuteness, which constitutes the great beauty of all perfect Music, constitutes likewise its great difficulty. The time, or measure of a song are simple matters, which even a coarse and unpractised ear is capable of distinguishing and comprehending: but to distinguish and comprehend all the variations of the tune, and to conceive with precision the exact proportion of every note, is what the finest and most cultivated 437 ear is frequently no more than capable of performing. In the singing of the common people we may generally remark a distinct enough observation of time, but a very imperfect one of tune. To discover and to distinguish with precision the proper intervals of tune, must have been a work of long experience and much observation. In the theoretical treatises upon Music, what the authors have to say upon time is commonly discussed in a single chapter of no great length or difficulty. The theory of tune fills commonly all the rest of the volume, and has long ago become both an extensive and an abstruse science, which is often but imperfectly comprehended, even by intelligent artists. In the first rude efforts of uncivilized nations towards singing, the niceties of tune could be but little attended to: I have, upon this account, been frequently disposed to doubt of the great antiquity of those national songs, which it is pretended have been delivered down from age to age by a sort of oral tradition, without having been ever noted or distinctly recorded for many successive generations. The measure, the humour of the song, might perhaps have been delivered down in this manner, but it seems scarcely possible that the precise notes of the tune should have been so preserved. The method of singing some of what we reckon our old Scotch songs, has undergone great alterations within the compass of my memory, and it may have undergone still greater before.
The distinction between the sounds or tones of singing and those of speaking seems to be of the same kind with that between the steps, gestures, and motions of Dancing, and those of any other ordinary action; though in speaking, a person may show a very agreeable tone of voice, yet if he seems to intend to show it, if he appears to listen to the sound of his own voice, and as it were to tune it into a pleasing modulation, he never fails to offend, as guilty of a most disagreeable affectation. In speaking, as in every other ordinary action, we expect and require that the speaker should attend only to the proper purpose of the action, the clear and distinct expression of what he has to say. In singing, on the contrary, every person professes the intention to please by the tone and cadence of his voice; and he not only appears to be guilty of no disagreeable affectation in doing so, but we expect and require that he should do so. To please by the choice and arrangement of agreeable sounds is the proper purpose of all Music, vocal as well as instrumental; and we always expect and require, that every person should attend to the proper purpose of whatever action he is performing. A person may appear to sing, as well as to dance, affectedly; he may endeavour to please by sounds and tones which are unsuitable to the nature of the song, or he may dwell too much on those which are suitable to it, or in some other way he may show an overweening conceit of his own abilities, beyond what seems to be warranted by his performance. The disagreeable affectation appears 438 to consist always, not in attempting to please by a proper, but by some improper modulation of the voice. It was early discovered that the vibrations of chords or strings, which either in their lengths, or in their densities, or in their degrees of tension, bear a certain proportion to one another, produce sounds which correspond exactly, or, as the musicians say, are the unisons of those sounds or tones of the human voice which the ear approves of in singing. This discovery has enabled musicians to speak with distinctness and precision concerning the musical sounds or tones of the human voice; they can always precisely ascertain what are the particular sounds or tones which they mean, by ascertaining what are the proportions of the strings of which the vibrations produce the unisons of those sounds or tones. What are called the intervals; that is, the differences, in point of gravity and acuteness, between the sounds or tones of a singing voice, are much greater and more distinct than those of the speaking voice. Though the former, therefore, can be measured and appreciated by the proportions of chords or strings, the latter cannot. The nicest instruments cannot express the extreme minuteness of these intervals. The heptamerede of Mr. Sauveur could express an interval so small as the seventh part of what is called a comma, the smallest interval that is admitted in modern Music. Yet even this instrument, we are informed by Mr. Duclos, could not express the minuteness of the intervals in the pronunciation of the Chinese language; of all the languages in the world, that of which the pronunciation is said to approach the nearest to singing, or in which the intervals are said to be the greatest.
As the sounds or tones of the singing voice, therefore, can be ascertained or appropriated, while those of the speaking voice cannot; the former are capable of being noted or recorded, while the latter are not.

ON THE
EXTERNAL SENSES;
THE Senses, by which we perceive external objects, are commonly reckoned Five in Number; viz. Seeing, Hearing, Smelling, Tasting, and Touching.
Of these, the four first mentioned are each of them confined to particular parts or organs of the body; the Sense of Seeing is confined to the Eyes; that of Hearing to the Ears; that of Smelling to the Nostrils; and that of Tasting to the Palate. The Sense of Touching alone 439 seems not to be confined to any particular organ, but to be diffused through almost every part of the body; if we except the hair and the nails of the fingers and toes, I believe through every part of it. I shall say a few words concerning each of these Senses; beginning with the last, proceeding backwards in the opposite order to that in which they are commonly enumerated.
