The greatest service which he rendered me, however, was the intelligence that all that were preserved of Mozart's letters had been presented to the Mozarteum in Salzburg by the Frau Baroni-Cavalcabo, to whom they were bequeathed by Mozart's son Wolfgang. In November of the same year I repaired, therefore, to Salzburg. I here found the only remains of that complete correspondence which Nissen had edited, viz., the letters between 1777 and 1784, just as he had made use of them; fortunately they embraced the most important period of the biography. A cursory glance convinced me that Nissen had been not only inexact and arbitrary in his selections in matters of detail, but that he had altogether suppressed the most important events affecting the proper understanding of the period. Here, then was much to be done; but it was richly worth the trouble. Through the kind assistance of the secretary of the Mozarteum, Dr. v. Hilleprandt, and of the custodian, Jelinek, I was enabled to give my whole attention to the work. I collated the letters printed by Nissen, like an LIFE OF MOZART. old schoolman, copying them entire or making voluminous extracts. One may boast of one's industry, and I can offer an unimpeachable witness of mine in old Theresa at the Golden Ox, who afterwards forgot my name, but remembered me as the professor who sat in his room for more than three weeks writing from morning to night. Fortunately, it was bad weather, or it would have been too hard a trial, even for a professor, to sit in his room all day at Salzburg. But the usually hateful task of transcription was on this occasion a real enjoyment. I could fancy myself in intercourse with the man himself as I lived his life again letter by letter.

I could realise the emotions of joy or sorrow which had prompted his words, the impressions which they had made on the recipients, and even the variations in the handwriting grew to have their own significance. It is my most earnest wish that some breath of this feeling may have passed into my own performance, but it would scarcely be possible to' reproduce the inspiration which contact with the letters awoke in myself.

On the completion of this task, I made researches for any of Mozart's compositions which might still remain in Salzburg; I failed, however, to discover any. Although Mozart's sister, his widow, and her sister had lived in Salzburg within the last ten years, it had occurred to no one to make inquiries concerning their great countryman, or to preserve to posterity the rich treasures of family tradition which encircled his whole life; I found, when I inquired, that all was as completely forgotten, as irrecoverably lost as his grave. Nor had anything further been preserved in the way of family papers and documents. (After the death of Mozart's eldest son Carl, all that he possessed of letters—written during the journeys of 1762 to 1775—and other documents, were placed in the Mozarteum.)

Treasure such as that correspondence I could scarcely expect to excavate elsewhere; but through the kindness of friends and well-wishers many letters have been placed at my disposal which have added to the interest, more particularly of Mozart's later years. I have no doubt that many INTRODUCTION. documents are still hidden in autograph collections and elsewhere; perchance my book may open the eyes of the possessors to the true value of their treasures, and I shall consider it as a rich reward of my labours if they aid in bringing to light any such relics of Mozart.

Assistance of another kind, not less important than the foregoing, came from André's collection. It is well known; that the Hofrath André purchased from Mozart's widow the entire collection of Mozart's original manuscripts, of printed and unprinted works, and this collection, with the exception of a few pieces disposed of at an earlier date, was preserved in Frankfort entire, in the possession of André's heirs, as denoted by a "Thematic Catalogue of the original manuscripts by Mozart in the possession of Hofrath André" (Offenbach, 1841). Leopold Mozart carefully preserved all Wolfgang's youthful works, and at his death they came into the son's possession: although not by any means so careless about his compositions as he has been represented, he, nevertheless, lost or gave away a considerable number. After his death, however, it was found that his works previous to his residence in Vienna had been preserved almost entire, and by far the greater number of those of later years. André's collection contains further the enumeration, in Mozart's own handwriting, of his works from his earliest years in almost unbroken succession to his death. The more important and greater number of his compositions previous to 1780 are still unprinted, and many of the printed ones are so carelessly edited that a comparison with the original is indispensable. The importance of André's collection is manifest, and it is probable that none of equal value, historical and artistic, exists for any other great master, whatever be his art. (Unhappily, the apprehension that Germany could conceive no worthier or more lasting way of honouring Mozart than by the erection of statues and busts has been fulfilled, and Mozart's manuscripts have already been in great measure dispersed.)

Convinced that a review of Mozart's musical development would be impossible without an exhaustive knowledge of his youthful works, I repaired to Frankfort in the summer LIFE OF MOZART. of 1853, in order to examine this remarkable collection. The brothers Carl and Julius André granted me ready access to it, and kindly prepared me an apartment in their house, where I had full liberty to study the MSS. and make what notes and extracts I pleased; a task which occupied five weeks. As it proceeded, I could not but feel that the most accurate notices could not give the fresh impression of the actual work. Here again, the brothers André came to my aid, displaying throughout a warmth of interest in my work, and a liberality which I could not have ventured to expect; they provided me, as my work progressed, with each particular manuscript on which I was engaged, so that my remarks could be grounded on the actual examination of every composition. Without the confidence and aid of these gentlemen, my book could not have succeeded in attaining that wherein I place its essential value. It is owing to their courtesy and kindness that I may boast, not only of a perfect acquaintance with all Mozart's works, with few and unimportant exceptions, but also of having enjoyed the singular happiness and advantage of studying the greater number of them in his own handwriting.

You will perceive, my dear friend, that all this led, of necessity, to fresh disclosures, to a fuller and more accurate insight into that which had hitherto been only partially known; and you will further take for granted that I, as a "philolog," would not neglect such researches into the literature of my subject as should bring together the scattered materials available for my task. But you must keep in mind that musical literature is not so accessible as philological; and that many expedients, which lighten our labours in the latter path, are wholly wanting in the former. I am, therefore, far from flattering myself that I have even approached a complete study of the literature of my subject. I only aimed at such a study so far as it concerned main principles; for to become acquainted with, or even to quote, everything that has been thought, dreamt, or raved concerning Mozart's music was as far from my intention as from my desire. I was more than satisfied with what came in my way of this kind in the course of my reading, and my INTRODUCTION. readers will be more than satisfied with what I offer them of it by way of example.

My first aim, then, was the verification and authentication of facts, and their unbiassed statement, so far as this was of interest. The written or authentic verbal traditions of Mozart and his family were here my chief dependence, and, except where some special authority is adduced, Nissen's correspondence forms the basis of my narrative. But since it was my wish to bring together all that appeared of lasting interest, and to dispense with Nissen's collection, for all readers who do not desire to search and prove for themselves, I have, therefore, quoted verbally from the letters wherever it was feasible, and have not hesitated to displace them where it answered my purpose in the narrative. I have in every case indicated the letters by their date, without mentioning whether they have been printed by Nissen or not. (They may be readily referred to in the careful collection of L. Nohl, "Mozarts Briefe": Salzburg, 1865.)

I must remark, by the way, that my version cannot be verified by Nissen, since his is neither accurate nor entire; and in order to avoid any misunderstanding, I may also mention, that besides the collections referred to above, many single letters of Leopold and Wolfgang Mozart have come to hand, to which I was able to make more exact reference. As a matter of course, I have made use of originals whenever they were to be had, and of Nissen's version only when they were wanting. From you, my dear friend, I need only request confidence in my scrupulous honesty as to these matters, and I have hope that my book may inspire the reader with a belief in the accuracy of my rendering. It need scarcely be said that I have not made the slightest alteration in the style and expressions of the letters. I have only taken a few liberties with the orthography in order not to distract the reader's attention unnecessarily from the characterisation. I have accurately indicated any reference to authorities other than the letters.

It has been my aim to represent, not only what immediately concerns Mozart, but also the time in which he lived, his circumstances, and the persons with whom he came in LIFE OF MOZART. contact, so far as all these affected the development of his genius. And here again I found the need of trustworthy information. Well informed as we may be on the history of literature and culture during the latter half of the eighteenth century, yet our information as to musical events and persons is meagre and obscure, and we know least of those regions which are of the greatest interest in the history of music. I doubt not that an historian, occupied with the study of this age, would discover much that has escaped me of interest, although I have heard even such complain of the poverty of material.
