| On the left is Bartók Béla. He used a symmetrical plan for several pieces of music, which employed of five movements. This arrangement is often referred to as an arch. The most symmetrical of these pieces is the fourth string quartet. The main themes of the first and last movements are identical; in fact the last page of each movement is almost the same. The theme is like a little arch of notes. The themes of the second and fourth movements are also very similar, differing only in tempo. Each looks rather like a perspective view of a bridge with three arches receding into the distance. Supported in the centre of all this is a an eloquent and passionate piece of music. It contains elements from the sounds of nature and from folk music. | It also seems to
contain an ever-decreasing series of golden sections, like a sunflower.
On the right is Kodály Zoltán, a composer, and a collaborator and friend of Bartók. These busts are close together on Margit-sziget in Budapest. After Bartók heard Dósa Lidi singing, in 1904, he became very interested in folk music, as did Kodály, and in time their music became a bridge between "art music" and "folk music". In the case of Bartók, the music is perhaps also a bridge connecting nature, art and science, three areas of great interest to him. |
| Composing a piece of music presents technical problems, like
building a bridge. You have some idea of the span of time that needs to be
filled . You have to decide on the number of sections or
movements. You also have to decide on a means of relating these movements
to create a coherent whole . This process goes on right down to the smallest
details, until the construction is as satisfactory as you can make it.
The artistic person can create whatever she or he likes, as long as a living can be made from it, or by some other means. |
Building a bridge is different . Economy is far more important than in art. The bridge designer is forced to work with what nature offers, rather than with a blank sheet of paper. The width of the crossing, the type of ground, the depth of water, the range of the tides, and the navigational requirements, for example, are not under the designer’s control. But he or she can use art and science to produce the best solution to the problems. And solving the problems may lead to great ideas, just as the search for a line with the right rhyme and rhythm may lead to an idea that a poet might not otherwise have had. |
| At the beginning of Beethoven’s quartet Opus 131, or Bartók’s Music for Strings, Percussion and Celeste, both seem not so much like tuneful, foot-tapping music as constructing something. The Bartók piece is literally built up, towards a tremendous climax, from which it descends quite rapidly on the other side. | The Beethoven piece gives a great sense of density, in terms of music per minute. A musician could explain this, but as with bridges or nature, we can enjoy things without understanding most of the details. But nothing is lost if we learn more – science does not spoil pleasure – it provides an extra dimension. |
| Many
kinds of art and science involve structure and symmetry. In
another part of this web-site there are pages about symmetry and
broken symmetry in physics.
Perfect symmetry in art would be rather boring. On the other hand, an art in which nothing is related to anything else would be very odd. Even in a painting by Jackson Pollock, there is relationship between the components, and the paintings are recognisably different from each other. They have not much structure, and not much symmetry, except in the sense that a "truly random" object is about the same at any point.
|
On
the other hand, poetry that rhymes and has metre is both well structured
and highly symmetrical. The most symmetrical poem would consist of
the same word repeated many times.
The symmetry is reduced by breaking it into lines, and grouping these into stanzas. The lines are generally all different. But the poem is held together by the rhyming scheme and the metrical pattern. So we have an example of broken symmetry. There may be occasional imperfect rhymes or feet that are not a part of the rhyming scheme. But these may even be used to emphasise a point. |
| Prof Ian Stewart, in "Life’s Other Secret (Penguin), shows how broken symmetry and simple rules can generate complicated structures and behaviour. So symmetry and patterns arise in nature as well as in art and engineering. | What are the differences between "popular" music, "folk" music, and "classical" music? In fact there are so many forms of music that this probably cannot be answered. But at least we can ask how they differ in complexity of structure and the degree of ornamentation of those structures. |
| In an article about Bartók, Kodaly wrote that art and science are not unrelated, and that someone can achieve greatness in both. This is surely true of the best bridge builders, whether the bridge is a humble footbridge or a great span. The article is quoted in "Bartók Remembered", by Malcolm Gillies, published by Faber and Faber. | C P Snow made a cause out of "The Two Cultures". As there are thousands of cultures and sub-cultures, from angling to zebra breeding, it is not obvious that this simple classification has quite the value that he thought. |

In Budapest, you can see a house once occupied by Bartók, and another once occupied by Kodaly. You can see manuscripts of the song and the intermezzo from the Háry János suite. If these were found in a thousand years time, they might be incomprehensible. If the finders did not know whether to read them from right to left or from left to right, or whether high notes were at the top or bottom, they would get no further. And without a knowledge of the instruments of a 20th century orchestra, they would not be able to hear these pieces as they were intended. The score is like the genetic code. It has all the information, but only if you have the correct environment, consisting of a suitable group of players and their instruments. Trying to recreate extinct animals may fail for the same reason. The code is not enough, as Ian Stewart says in his book – "Nature’s Other Secret." Back to Home page back to Bridges
