like
†††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††††† †††††††††††††††††† †† ††††††Pythagoras
†††††††† It is considered
that a fifty three -steps musical system was for the first time described by N.Mercator
(not to confuse with a famous cartographer) at the beginning of the XVIII, but later re-opened by “аnaka and Bosanket.
Yet exists a strong basis to supposeВ that it was known much earlier in ancient
†††††††† As it has already been shown earlier, under the consequent
procedure of raising by a quint and bringing all forming grades in the initial
octave, the first 11 quints (along with є1В
taken for source) give seven main and five lowered by the semitone musical notes,
but with 12-th quint this harmonic series is repeated with the shift upwards by
the micro interval of Pythagorean comma
(microtone I order D) В and so
in each cycle of 12 quints.
†††††††† †As far as an interval of a halftone contains
less than 4D
-† about 3.85, how shows a calculationВ then in
fifty third quint (12 x 4 + 5) a step є
54 will be formedВ which "is connected" with the source step є1 faВ
accepted as a unit value. The new positive micro
interval of II order s
by the value near 1/6.5D† (or 3.6 cent) is obtained - Fig. 1.
Thus, the first cycle of 53 quints is terminated.
†††††††† Like the
first 3 harmonic numbers answer to division of an octave interval into 2 quints
and 2 quarts with forming a whole tone interval between them, 5 numbers form sound
raw of pentatonic gamma (without semitones), 7 - seven-step (diatonic) gamma with two semitone
intervals (mi-fa and si-do1)В and 12 numbers - twenty-step
semitone (chromatic) gamma, consequently taken 53 quints gives a natural 53-step
gamma of natural build.
†††††††† 53 stepsВ
therebyВ numerologically answer the octave: 5+3=8В and follow its pattern
†††††††† As far
as the increased (#В formed by the retrograde motion of quints) and lowered (В
formed by direct motion) steps differs on the comma value in quint buildВ and
in the cycle of 53 four micro
intervals are formed in addition inwardly each semitoneВ a wholetone gap will
be divide into 9 micro intervals
("nonnas") -
Fig.
2. Seven of them in accuracy equal D (23.46 cent), but two (between 4Δ+
и ,
and between 3Δ+ and main notes) are
lowered by s
and equal 0.85D† (near 20 cents). Such division may be easily transformed
into 53-step equal (tempered) build - Fig.
3. Each micro interval δ in it must take the value =
1.0131642 (about 22.64 cents)В
differing from the natural micro interval D by a value near 1/29D (0.8 cents).
†††††††† †Structure of dividing the оctave interval in
the equal 53-step build is presented as follows:
††††††††††††††††††
†††††††† These inward
harmony steps assign the base of natural microchromatics
or so-called "enharmony" (in Greek έναρμόνιον†
γένος = "regime kind") build. In consequence of equal dividing of
a semitone the 53-step gamma allows to build the
††††††††
††††††††
†††††††† All
these steps are linked through the relations of clean quints and quarts (3:2
and 4:3)В i.e. may to be made one
from another in a certain number of quint moves. The accepted twelve-steps
temperationВ as it is well- knownВ is possible only at the condition of
reduction all quints by the interval 1/12 part of a Pythagorean comma (D)В what
means no other than the refusal of consonants.
†††††††† †Take, for example, a table of comparative
frequencies for the 12-steps temperated, clean and the 53-step equal build:
†††††††† From
this comparative table it is possible to see that the fifty three step musical
system contains the clean quints and quarts (difference in the fifth decimal
sign), coinciding in this feature with the "clean build". Its minor tercie also corresponds to a minor
tercie in the clean build (difference in the third decimal sign). What concerns
a major tercie, which "noneuphony"
is considered to be the defect of the quint build (and in the 53-step formation
it is closer to "tempered", than to "clean" major tercie), †its "purity" can be reached by
reduction of an upper or raising of a lower note of the interval by 1 microtone (by δ-alteration).
†††††††† SoВ for
the lowered on 1 microtone step mi (miΔ-)
frequency takes a value †1.248989
comparatively to do, corresponding to
an interval of 389 cents, that is practically interchangeable with the "clean"
major tercie (386 cents). Alterations by a microtone (23 cents) may be reached
by programming (in the сase
of electronic instruments) to achieve a "clean" major tercie sound.
†††††††† For about
three centennialsВ passed after BachВ European musical composition has exhausted
its all initially creative potentialВ in the significant measure obliged to a success
of the 12- step tеmperation.
On the great part of music amateurs an accent of interest exhibit the more and
more bias to the alternative directions of "ethnic classicism". At
the same time the attempts of widely using of microchromatics have been
undertaken since XIX centuryВ and it was one of the main kinds of an ancient
and antique music. Creations of all significant composers of the second half of
XX century demonstrate a tendency to overcome the oppression of a twelve-sound temperation.
†††††††† A 53- step
build fills in a main defect of the latter - an absence of consonances, for the art, which
nature lies in harmony, becomes a critical factor. Together with that it is
based on numeric laws of music, distinguishing in an artificial clean building,
which theoretical basis is arbitrarily elected.
†††††††† Getting
closer to the oriental music (not having a fixed row) in the sound compositionВ
and possessing together with that the tempered closed build qualities (differing
with the Pythagorean system), the fifty three-steps system enables to use all
developed in the West means of musical compositions, at the same time vastly
increasing their borders.† The problemВ
seems to beВ in the technical entailmentВ but this question does not appear for
electronic programmed instruments.
†††††††† One can be possibly sureВ that the efforts,
undertaken both on the part of sciences and modern art to remove a West
civilization from a spiritual and ecological blind-alley, to restore its third
(axial) lost measurement -
and hereupon reassessment of many earlier established valuables† -
†do not pass such a forming image of culture
element, as basis of its musical system.
