The conventional seating-plan of the orchestra will help the reader to familiarize himself with the instruments. In concerts the stringed instruments are always placed at the front of the stage, with the wind-instruments behind them, in order that the tone of the strings may come out fully and without obstruction. The first violins are always on the left of the audience, and second violins on the right. Violas are usually placed immediately behind the second violins, though some conductors put them behind the first. The ’cellos are arranged usually on the side opposite the violas, and double-basses are placed at the sides or the back, according to the conductor’s idea. The wood occupies the middle of the stage, and the brass and instruments of percussion are at the rear. The diagram on the next page shows the seating plan of the Boston Symphony Orchestra.

Seating Plan of the Boston Symphony Orchestra.
Amateurs will find that they must extend their musical knowledge a little, if they desire to read orchestra scores. Persons who have studied only piano playing are nonplussed when they find themselves in the presence of transposing instruments and other clefs than those known as the treble and the bass. I have already briefly explained the peculiarity of what are called transposing instruments, but it will be well to give the reader some further help in dealing with them in reading scores. A question which I have frequently heard is, “Why don’t they make all instruments in C?” The answer to this question is that there could only be one reason for doing so, namely, to make it easy for amateurs to read scores. There are many more substantial reasons for making instruments in various keys. For instance, brass instruments produce most easily and with the finest tone and richest sonority their natural notes—those notes which are produced without any aid from valves or pistons as the notes of a cavalry bugle. If a composer in writing a brilliant march in B natural, a bright and incisive key for the strings, wishes to introduce trumpets, he can make most effective use of those in B natural. But it is not possible always to have clarinets, trumpets, and horns in every key ready for instant use, so custom and experience have induced musicians to make a judicious selection. Clarinets in A and B flat are now used far more than those in C. As Gevaert says: “The choice among the three clarinets is not always made from the simple consideration of facility; often it is guided by the character of the tone peculiar to each. The clarinet in C has a timbre brilliant almost to rudeness.” He further notes that it is therefore used by the classic composers mostly in brilliant movements in the simple diatonic scales. The clarinet in B flat or that in A may be chosen for reasons of a like nature. The reader, however, will probably be more interested in knowing how he is to read clarinet parts. If they are in C, he will have no trouble, because there will be no transposition. A clarinet in B flat playing music written in C, sounds one tone lower than that scale. Hence the key of C is used for a clarinet in B flat only when the violins are playing in B flat.
In other words, every sound which issues from a B flat clarinet is one whole tone lower than that written in the score. If you write C, the instrument sounds B flat. If you wish the instrument to sound C, you must write D. If you wish it to sound F sharp, you must write G sharp. If you wish it to sound E natural, you must write F sharp or G flat.
The composer has the choice of two methods of writing his clarinet part. He may write always without any key signature and mark all flats and sharps as accidentals, or he may use a key signature. Custom has sanctioned the latter method, which is the more rational. I have just said that every tone which issues from a B flat clarinet is a whole interval below the written character. Therefore, all music for a B flat clarinet must be written one interval higher than it is intended to sound, and this, the reader will see, simply results in transposing a B flat clarinet part into a key one tone higher than that of the composition. For a composition in C write for B flat clarinets in the key of D. For one in D write for B flat clarinets in E. For one in E flat write for B flat clarinets in F. There is another simple way of looking at this matter. Clarinets in B flat have already two flats in their open scale. If you want them to play in C, you must contradict these two flats by two sharps, and two sharps are the signature of the key of D. Hence, write in D for B flat clarinets to play in C. In reading a score all that the amateur needs to do is to remember that every note written for the B flat clarinet sounds one tone lower than written. Thus the chord of C for two flutes, two oboes, and two clarinets might be written as at A so as to sound as at B.
In the case of clarinets in A the same principles apply. The clarinet in A sounds A when C is written, and it sounds the entire scale of A when the scale of C is written. As C is one tone and a half above A, it follows that notes for the A clarinet are always written a tone and a half higher than the sounds to be produced, and the score-reader must conceive the A clarinet parts as sounding that much lower than they are written. Thus, to get C out of an A clarinet, you must write E flat, and to make an A clarinet play in unison with flutes in the key of C, you must write in E flat for the clarinet. The chord just written would have to be rewritten thus:
One of the peculiarities of orchestra scores is that music for horns and trumpets is always written without any key signature—that is, just as if it were in C major—and all the sharps and flats are put in as accidentals. This makes difficult reading at times for an amateur. In order to aid the music-lover I give herewith the written notes and the corresponding real sounds of the horn in F, which is the most frequently used. The same table will answer for the trumpet in F.
The rules of transposition given above apply to all music for transposing instruments. A tuba in E flat, for instance, is one which sounds E flat when the composer writes C. Persons accustomed to sight-reading with a “movable Do” have very little trouble in the study of orchestra scores, and I earnestly advise all who wish to read scores to study sight-reading.
Next comes the matter of clefs. As I have stated, it is customary to write the viola part on the alto clef. When a bassoon or a ’cello runs up so high that it is inconvenient to employ the bass clef, the tenor clef is used, and if it goes still higher, the treble clef may be introduced. These various clefs are troublesome to the amateur because he is familiar only with the treble and bass clefs. The treble clef is known also as the G clef; because the character is placed upon the second line to indicate that the treble G is there located. A clef sign simply fixes the place of some note, and the others are located accordingly. The bass clef is also called the F clef, because the character is placed so as to indicate that F is on the fourth line. Now in the alto and tenor clefs the character is used, and its purpose is to locate the note C. In the alto clef it is on the third line, where B is in the treble clef. In the tenor clef it is on the fourth line, where D is in the treble clef. The question which will arise in the amateur’s mind is this: Which C is it that is thus located? The answer is simple and easily remembered. It is best expressed by the following illustration:
Here are two scales, one alto and one tenor, with the real sounds.
It will be seen from these illustrations that the C located by the clef sign in the alto on the third line and the tenor clef on the fourth line is the one situated on the first leger line below the staff in the treble clef. Having this fact in mind, the lover of orchestral music can learn, with a little practice, to read viola parts and ’cello or bassoon passages which run up into the tenor clef. The following illustration shows a ’cello passage with the middle measure written on the tenor clef, and also the same passage written wholly on the bass clef:
In some scores the music-lover will find the three trombone parts written on three clefs, alto, tenor, and bass, while in others they are written on the bass clef only. I have already noted that bass clarinet parts are written sometimes on the treble and sometimes on the bass clef. The former is always used by French composers, and the latter nearly always by Germans.
