This is a more complex matter than it might appear. True, in some instances setup can be capricious, but generally a lot of thought goes into it. It's generally a matter of sound and logistics. One question to be answered is what arrangement of the orchestra in a given building will produce a given sound? How deep is the stage? How wide? What are the hall's acoustics? Live? Dead? Bright? Dark? Bass light or heavy? If you want to compensate for a characteristic you might set up one way. If you want to take advantage or reinforce that characteristic, you might do the opposite. Another might be what arrangement will allow players to hear each other. That is important in a building with poor stage acoustics. Some buildings are good enough that almost any setup will work. Others, say with poor stage acoustics or weak bass, are limiting. Almost always in poor buildings, and even in good ones, the solution of one problem is the cause of another. Some of this aspect of the issue is cut and dried, but if you use your imagination just a bit, explore all the permutations, then factor in the more subjective ones I'll talk about in a minute, it is possible to conjure up a lot of factors and a lot of combinations and conclude, accurately, I think, there is no ideal setup. The building aside, there are other issues and preferences. For arguments sake, let me start by saying that the most common arrangement of the strings is first and second violins on the left, cellos on the front on the right, and violas on the inside on the right. One of the major deviations from this is to split the first and second violins. That is, firsts on the left in front, seconds on the right in front. It wasn't long ago that separating the violins this way was the most common way of doing things. Listen to recordings by Boult or Monteux to hear the effect. Complicating the issue is that a lot of composers wrote with the split setup in mind. That is, they often wrote aleatoric effects between the sections: a line in the firsts would be answered by one in the second. (Think of the HSDP variation in Elgar's Enigma.) In Monteux's recording you hear the interplay. In most recordings, with both parts on the left you don't. Conductors used to prize this capability but you don't hear it so much any more. I guess the theory of putting both parts on the left is to allow all the f-holes to face outwards and to keep the violin sound more of a luminous mass. But there is always the argument that this lies in direct contrast to the setup composers were writing for. Of course, if you do split, you must face the question of what to put where the second violins were. I've seen the cellos here and also the violas. If it's the cellos, you face yet another issue. Where to put the basses? Do you keep them on the right or arrange them more in the middle behind the cellos? The latter keeps these bass instruments, which often play in octaves, together. It also tends to amass the bass in the middle of the orchestra. Is that what you want? (I like this setup a lot.) Does it work in the hall or is the result mud and would you be better off spreading the bass out even though it makes it hard for the cellos and basses to hear each other while they play often similar parts? Another variation is to keep the violins together, but switch the cellos and violas, i.e., put the cellos in the inside and the violas on the outside. The theory here, as I understand it, is that it allows the violas, the softest of the strings, to be heard more clearly. At the same time it weakens the bass. The Boston Symphony uses this setup, and I don't care for it much for that reason. Arrangement of the woodwinds is more consistent. The object is to keep the principals together and the flutes and clarinets on one side and the double reeds on the other. This keeps the bassoons close to their oboe relatives and also close to the lower strings (assuming they're on the right) (Though I've seen the Concertgebouw put the clarinets on the right and bassoons on the left.) The brass is more varied. One way is to spread them across the stage. Another is to group them toward the back toward one side or the other or the center. Sometimes you'll see a mix, e.g., trumpets with trombones behind them, then horns spread toward the middle. Or maybe the horns are the ones grouped. First and second in front, third and fourth in back. The issue here, obviously, is do you want the brass spread or grouped? The hall character may play a role here. Or just personal preference. This issue settled (if it ever really is), many conductors like the first trumpet and first horn together since they play so much, and so with each other. The first trombone can come into play too, if you find a way to put him/her behind the horn and trumpet, but the location of the first trombone vis a vis this issue is usually considered less important since the first trombone plays the least among the three. More of an question is where do you put the bass trombone because that instrument so often plays with the low strings. Generally, that part is placed near them. To the right in most setups, but maybe to the left in a split string setup. Percussion I know the least about. My guess is that hall acoustics and stage room are the biggest factors. And perhaps simple logistics of placement and players getting around. Sometimes the work you're playing on a given night may influence setup. Many pieces were written with split strings in mind. If one is a major work on a concert, sometimes the conductor will try to take advantage of that by using split strings for that concert. (I'm sure stage managers love changes like that from concert to concert.) I haven't seen this kind of thing done very often. Generally, when orchestras change setup, they stay with the new arrangement for a while. I might add that the kind of music an orchestra likes to play may dictate setup. And do you really want to get into the question of risers? Setup is often a matter of experiment. Conductors, for it is they who usually decide on this issue, are often fooling with setup trying to get the sound they want out of particular group of players in front of them. Stokowski was notorious for experimenting with some quite wild setups to produce different effects. I am in no way pretending to write a treatise on this subject. I couldn't do it anyway, but I'm sure someone could (and probably has). It's that complex. But I hope I succeeded in convincing you there is more to this issue than arbitrariness. Different setups do sound different, and they often affect the ways players interact with each other as well. Roger Hecht
