Even a hasty inspection of the written catalogue must convince the student that it contains principally entries of compositions possessing no value whatever. Every quadrille, ballad, and polka which has been published in England during the last fifty years appears to have a place here, and occupies just as ample space as Gluck's 'Alceste,' or Burney's 'History of Music.' This is perhaps unavoidable. If works of merit only were to find admission, who would be competent to draw the line between these and such as ought to be rejected? In no other art, perhaps, do the opinions of connoisseurs respecting the merit of any work differ so much as in music. Since music appeals more directly and more exclusively to the heart than other arts, its beauties are less capable of demonstration, and, in fact, do not exist for those who have no feeling for them. There are even at the present day musicians who cannot appreciate the compositions of J. Sebastian Bach. Forkel, the well-known musical historian, has written a long dissertation, in which he endeavours to prove that Gluck's operas are execrable.[1] Again, among the adherents of a certain modern school despising distinctness of form and melody may be found men who speak with enthusiasm of the works of Handel, Gluck, Mozart, and other classical composers, although these works are especially characterised by clearness of form and melodious expression. Besides, it must be borne in mind that even our classical composers have now and then produced works of inferior merit, which are nevertheless interesting, inasmuch as they afford us an insight into the gradual development of their powers.
In short, in a musical library for the use of a nation, every musical composition which has been published ought necessarily to be included. In the Musical Library of the British Museum it unfortunately happens, however, that many of those works are wanting which are almost universally acknowledged to be of importance. Indeed, it would require far less space to enumerate the works of this kind which it contains than those which it does not, but ought to, contain.
Again, the student must be prepared for disappointment, should he have to consult any of our scientific treatises on music. However, there may be more works relating to the science of music in the Library of the British Museum than would appear from the catalogue of music. Several have evidently been entered in the new General Catalogue. Would it not be advisable to have all the books relating to music entered in the musical catalogue? Even the most important dissertations on musical subjects which are found in various scientific works might with advantage be noticed in this catalogue. Take, for instance, the essays in the 'Asiatic Researches,' in the works of Sir W. Jones and Sir W. Ouseley, in 'Description de l'Egypte,' in the 'Philosophical Transactions.'
Thus much respecting the Musical Library in the British Museum. Let us now consider how a national musical library ought to be constituted. Premising that it is intended as much for the use of musical people who resort to it for reference, as for those who are engaged in a continued study of some particular branch of the art, the following kinds of works ought to form, it would appear, the basis of its constitution.
1. The Scores of the Classical Operas, Oratorios, and similar Vocal Compositions, with Orchestral Accompaniments.—Many of these scores have not appeared in print, but are obtainable in carefully revised manuscript copies.
2. The Scores of Symphonies, Overtures, and similar Orchestral Compositions.—The editions which have been revised by the composers themselves are the most desirable. The same remark applies to the scores of operas, oratorios, etc.
3. Vocal Music in Score.—The sacred compositions Alla Cappella, and the madrigals of the old Flemish, Italian, and other continental schools, as well as those of the celebrated old English composers. The choruses of the Greek Church in Russia, etc.
4. Quartets, Quintets, and similar Compositions in Score.—The study of these works of our great masters is so essential to the musician, that special care should be taken to secure the best editions. The classical trios for pianoforte, violin, and violoncello, and some other compositions of this kind, originally published in parts, have more recently been issued in score. The latter editions are greatly preferable to those in which the part for each instrument is only printed separately. The same remark applies to the concertos of Mozart, Beethoven, and other masters, which have been published with the orchestral accompaniment in score, as well as with the orchestral accompaniment arranged for the pianoforte or for some other instruments.
5. Sonatas, Fantasias, Fugues, etc.—Of all the classical works composed for a single instrument, the original editions, generally revised by the composers themselves, are indispensable. Besides these, the most important subsequent editions of the same works would be required. Beethoven's pianoforte sonatas, for instance, have been re-edited by several eminent pianists. It is instructive to examine the readings of these musicians, which differ in many points from each other.
6. Arrangements.—Those of operas, oratorios, masses, and other elaborate compositions with orchestral accompaniment, must necessarily be confined to the instrumental portion, otherwise they are useless either for study or reference. Those arrangements are greatly preferable which have been made by the composers themselves, or under their superintendence.
