(ββ) In this indeterminacy, however, music is unable to leave time. Rather it is compelled to define it more narrowly, to give it a measure, and regulate its stream according to the rules of such a measure. By virtue of this regular treatment we get the time-measure of tones. And here at once arises the question, wherefore then once and for all music requires such measure. The necessity of definite periods of time may be evolved from this fact, that time stands in the closest affinity with, the self in its simplicity, which apprehends, and has a right to apprehend, its inward life through the medium of tones; time, in fact, regarded as externality, essentially possesses the same principle, which is active in the Ego as the abstract foundation of all that pertains to the soul and spirit. If, then, it is the simple self, which as soul-life has to be made objective in music, so, too, the universal medium of this objectivity must be treated conformably to the principle of that subjective life. The Ego, however, is not the indefinite continuance and the unbroken[430] duration, but is only self-identity when we regard it as an aggregate and a return upon itself[431]. The assertion of itself, wherein it becomes object, is doubled back in the being thus self-for-itself; and it is only through this relation to itself that it becomes self-feeling, self-consciousness and so forth. In this aggregate, however, we find essentially a breaking off of the purely indefinite change, such as we held time to be in the first instance, in which the rise and suppression, the disappearance and renewal of the points of time were nothing but a wholly formal passage from every now to another present of similar character, and consequently nothing but an uninterrupted progression. In contrast to this empty process the self is that which itself persists by itself, the totality whereof essentially breaks up the undefined series of time points, creates an infraction into the abstract continuity, freeing the Ego, which recollects itself in this process of discrete division and finds itself again therein, from what is a purely external process of change.
(γγ) The duration of a tone does not, agreeably to this principle, pass away in a process of relative indeterminacy, but emphasizes with its beginning and end, which accordingly is a definite beginning and cessation, the series of the time moments, which, apart from it, are not thus distinguishable. If, however[432], many tones follow one after another, and every one of them receives a duration which can be separately distinguished from each other, then we must assume that instead of having that original indefinite series devoid of content, we only once more get by a converse process the fortuitous, and, along with this to a like extent, the indefinite variety of particular quantities. This unregulated rambling about contradicts quite as much the unity of the Ego as the abstract progress forward; and it can only find itself reflected and satisfied in such a varied mode of definition in so far as single quantities are brought under one unifying principle, which for the reason that it subsumes the particular parts under its synthetic embrace, must itself be a definite unity, yet in the first instance as merely an identity of external application can only persist as one of an external type.
(β) And this carries us to the further principle of co-ordination which we find in the time-beat.
(αα) The first thing to be considered here consists in this, that, as stated, distinct divisions of time are united in a unity, in which the Ego independently creates its identity with itself. Inasmuch as the Ego in the first instance only supplies the foundation as abstract self this equability, in respect to the advance of time and its tones, can only assert itself as operative under the mode of a uniformity that is itself abstract, that is to say as the uniform repetition of the same unity of time. Agreeably to the same principle the beat according to its simple definition can only consist in this, that it establishes a definite unity of time as measure and rule not merely for the deliberate[433] breaking up of the time-series held previously without such distinction, but also for the equally capricious duration of single tones, which are now apprehended together under a definite bond of union, and that it permits this measure of time to be continuously renewed in abstract uniformity. In this respect time-beat possesses the same function as the principle of symmetry in architecture, as, for instance, when this places side by side columns of similar height and thickness at intervals of equal distance, or co-ordinates a row of windows, which possess a definite size, under the principle of equality. We find present in this case, too, an assured distinction of parts and a repetition in every way complete. In this uniformity self-consciousness discovers itself once more as unity, in so far as it in part recognizes its own equality in the co-ordination of a fortuitous variety; partly, too, in the return of the same unity, it is recalled to the fact that it has already been there, and precisely by means of its return asserts itself as the prevailing principle[434]. The satisfaction, however, which the Ego receives through the time-beat in this rediscovery of itself is all the more complete because the unity and regularity do neither apply to time or tones as such, but are something which is wholly appertinent to the Ego, and is carried into the time relation by the same as a means of self-satisfaction. We do not find this abstract identity in what is wholly of Nature. Even the heavenly bodies retain no regular time-measure[435] in their motions, but accelerate or retard their course, so that they do not pass over equal spaces in identical periods of time. The same thing may be said of falling bodies, with the motion of projectiles, etc., and we may add that animal life to a still less degree regulates its running, springing, and seizing of objects on the principle of an exact recurrence of one definite time-measure. In this respect the time-measure of living things proceeds far more completely from spiritual initiative than the regular definitions of size applicable to architecture for which we may more readily discover analogies in Nature.
(ββ) If, however, the Ego is to return upon itself by means of the time-beat by thus appropriating throughout an identity which it itself is and which proceeds from itself, we imply in this, in order that the distinct unity may be felt as a principle, that in a similar degree what is presented to it should be that which is unregulated and not uniform. It is in short only through the fact that the definite beat of the measure prevails over and co-ordinates what is capriciously unequal, that it asserts itself as unity and regulating principle of a fortuitous variety. It must consequently appropriate the same within itself, and suffer uniformity to appear in that which is not so. This it is which first gives to the time-beat its specific and essential definition to be asserted too in contrast to other measurements of time, which can be repeated relatively to the same principle.
(γγ) By reason of this the multiplicity which is enclosed in a given time-measure possesses its definite standard according to which it is divided and co-ordinated. From this we arrive, in the third place, at distinct kinds of time-measure. The first thing of importance to notice in this connection is the division of time according to either an even or an uneven number of equally divided parts. Of the first kind we have, for example, the two-four and the four-four time. In these even number is predominant. Of the opposite kind is the three-four time, in which the co-ordinate divisions constitute a unity of equal parts, of course, but in a number that is uneven. Both types are to be found united in six-eight time, to take an example, which no doubt numerically appears to be similar to the four-four time, but as a fact, however, does not fall into three but into two divisions, of which, however, the one no less than the other, relatively to its closer aspect of division, accepts three, that is an uneven number, as its principle.
A particularization of this kind constitutes the constantly repeated principle of every particular measure of time. However much notwithstanding the definite time-measure is bound to control the variety of the time-duration and its longer or shorter sections, we must not therefore extend its effective power to the length that it places this variety in subjection in a wholly abstract way, that in short, for example, in the four-four measure only four notes of equal length as fourths can appear, in the three-four time only three, and so forth. The regularity restricts itself to this, that as, for instance, in the four-four time the sum of the separate notes are only equal to four equal parts, which may not only be divided into eighths and sixteenths, but conversely may again contract into less divisions, and indeed are capable moreover of more diffuse division.
(γ) The further, however, this elastic mode of differentiation is carried the more necessary it is that the essential divisions of the time should be asserted as predominant and also should be indicated in an effective way as an illustration of the fundamental principle of their co-ordination. This is carried out by the rhythm, which first gives vital significance to time-measure and the beat. With respect to this vitalization[436] we may distinguish the following points.
(αα) In the first place we have accent, which to a greater or less degree attaches in an audible way to definite divisions of time, while others pass by on the other hand without an accent. By virtue of such emphasis, or lack of emphasis, which is itself of various kinds, every particular measure of time possesses its particular rhythm, which is placed in exact association with the specific mode of division to which its rhythm applies. The four-four time, for instance, in which an even number is the principle of division, has a twofold arsis; on the other hand there is that on the first note or fourth division, and then, though in weaker power, on the third. The first is called on account of its stronger accentuation, the strong accent, the second in contrast to it the weak one. In the three-four time the accent rests entirely on the first fourth, in six-eight time on the contrary it is on the first of the eight divisions and the fourth, so that in this case the twofold accent asserts a division of equal length in two halves.
(ββ) In so far as music is an accompaniment rhythm is brought into essential relation with poetry. In the most general way I will on this merely venture the observation that the accents of the musical beat ought not to directly contradict those of the metre. If, for example, one of the unaccentuated syllables, relatively to the rhythm of the verse, is placed in a strong accent of the beat, while the arsis, or it may be the caesura, falls in one of the weak accents of the music, then we get a false opposition between the rhythm of the poetry and that of the music which it is better to avoid. We may affirm the same thing with regard to the long and short syllables. These also ought in general to fall into harmony with the duration of the tones, so that the longer syllables are coincident with the longer notes, the shorter with the shorter, albeit this accordance is not to be pressed with absolute precision, inasmuch as music is frequently permitted greater play for the duration of its long notes, no less than for the exuberant subdivision of the same.
