which E gives only the D,
on the clarinet in B♭.
A habit as vicious, and still more baneful, has crept into many orchestras since the introduction of horns with cylinders and pistons: it is that of playing in open sounds; by means of the new mechanism adapted to the instrument, those notes intended by the composer to be produced in closed sounds, by means of the right hand within the bell. Moreover, the horn-players nowadays, on account of the facility afforded by the pistons or cylinders for putting their instrument into different keys, use only the horn in F whatever may be the key indicated by the author. This custom gives rise to a host of inconveniences, from which the conductor should use all his efforts to preserve the works of composers who know how to write.
He should also set his face against the economical fashion adopted by certain theatres—called lyric—of causing the cymbals and the long drum to be played by the same performer. The sound of the cymbals when attached to the drum—as they must be to render this economy feasible—is an ignoble noise, fit only for bands at tea-gardens. This custom, moreover, leads mediocre composers into the habit of never employing one of these instruments without the other, and considering their use as solely confined to forcibly marking the accented parts of the bar. This is an idea fruitful in noisy platitudes; and one that has brought upon us the ridiculous excesses beneath which, if a stop be not put to them, dramatic music will sooner or later sink.
I conclude by expressing sincere regret at beholding choral and orchestral studies still so badly organized. Everywhere, for grand choral and instrumental compositions, the system of rehearsals in the mass is maintained. They make all the chorus-singers study at once, on the one hand; and all the instrumentalists at once, on the other. Deplorable errors, innumerable mistakes, are thus committed—particularly in the intermediate parts—errors which the chorus-master and the conductor do not perceive. Once established, these errors degenerate into habits, and become part and parcel of the execution.
The hapless chorus-singers, moreover, are by far the worst treated of all the performers during their studies, such as they are. Instead of giving them a good conductor, knowing the times of the different movements accurately, and proficient in the art of singing, to beat the time, and make critical observations: a good pianist, playing from a well-arranged pianoforte score, upon a good piano; and a violinist, to play in unison or in octave with the voices as each part is learned alone—instead of these three indispensable artists, they commit them (in two-thirds of the lyric theatres of Europe) to the superintendence of a single man, who has no more idea of the art of conducting than of that of singing, who is generally a poor musician, selected from among the worst pianists to be found, or who cannot play the pianoforte at all—some old superannuated individual, who, seated before a battered out-of-tune instrument, tries to decipher a dislocated score which he does not know, strikes false chords major, when they are minor, or vice-versa, and under the pretext of conducting and of accompanying by himself, employs his right hand in setting the chorus-singers wrong in their time, and his left hand in setting them wrong in their tune.
One might believe one's self in the Dark Ages, on witnessing such an exhibition of Gothish economy.
A faithful, well-colored, clever interpretation of a modern work, even when confided to artists of a higher order, can only be obtained, I firmly believe, by partial rehearsals. Each part of a chorus should be studied singly until it is thoroughly known, before combining it with the others. The same step should be taken with regard to the orchestra, for a symphony at all complicated. The violins should first be practised alone; the violas and basses by themselves; the wooden wind instruments (with a small band of stringed instruments, to fill in the rests, and accustom the wind instruments to the points of re-entrance) and the brass instruments the same; and very often it is necessary to practise the instruments of percussion alone; and lastly, the harps, if they be numerous. The studies in combination are then far more profitable, and more rapid; and there is then good hope of attaining fidelity of interpretation, now, alas, but too rare.
