In about a year from the date of Haydn's engagement Prince Paul Anton died, and the event marked a further advancement in the composer's fortunes. Prince Nicolaus, who succeeded his brother, was a passionate lover of the arts and sciences, in addition to being one of the most generous and warm-hearted of men. His succession implied an added magnificence and pomp to what seemed already perfect. To Haydn he gave an assurance of his good-will and appreciation by raising his salary from four hundred to six hundred florins, and, later, to seven hundred and eighty-two florins (or £78), allowed him to select additional musicians, and at the same time gave him to understand that he should look for an increase in the number of performances. The Prince himself played the baryton, or viola di bardone—a stringed instrument of sweet, resonant tone, which, like the viol da gamba, to which it bore some resemblance, has long since ceased to be heard. As the Prince prided himself on his playing, Haydn was required to produce endless pieces for the instrument, and he was even at considerable pains to acquire a knowledge of the baryton itself, thinking thereby to afford his master pleasure. To his chagrin, however, he discovered that his efforts in this direction were not at all appreciated by the royal performer, who had no fancy to see himself outskilled.

In 1766 Werner died, and Haydn succeeded to the full title. He had thus reached the summit of his boyish ambition, and could look back with pride to those early days when he studied the 'Complete Chapel-master' in his lonely garret, and longed for the day to come when his father's dream might be realised. And what of the parents whom he had left behind in the little village? How had they fared during these long years of struggle and success? The mother died seven years before Haydn received his appointment to the Esterhazy family, and while he was still striving to make his way; and the pleasure which success had brought to him must have been tinged with the regret that she had not lived to witness it. Mathias had married again, but he managed to find his way to Eisenstadt, where, to his pride and joy, he heard Joseph addressed as 'Herr Capellmeister!' Thither, also, came Michael, who had been appointed director and concertmeister to Archbishop Sigismund of Salzburg, to spend several happy days with his elder brother.

Haydn's fame as a composer had spread far beyond the walls of Eisenstadt. Musicians of Leipzig, Paris, Amsterdam, and even London, were playing his symphonies, trios, and quartets, whilst the Wiener Diarium—the Austrian official gazette—for 1766 refers to him as 'the favourite of our nation,' and pays him the high compliment of comparing him with Gellert, the most esteemed poet of the day. 'What Gellert is to poetry Haydn is to music,' writes the critic.

Werner's death was shortly followed by an event which implied a still greater change in Haydn's surroundings. Prince Nicolaus had been engaged in carrying out a scheme for the rebuilding of his shooting-box near Süttör on a scale of magnificence rivalling that of Versailles in its palmiest days, and, the works being completed, the Prince moved thither with the major portion of his household. No more lonely spot or one more unhealthy in its natural state, could have been chosen than that which formed the site of the new residence. Standing in the middle of a salt marsh, forming the southern extremity of the great lake called the Neusiedler-See, Esterház, as the palace was named, was quite cut off from the outside world. The work of draining and reclaiming the land, however, had effected such an improvement that what in its primitive condition had been little better than desolate swamp, resounding to the harsh cries of wild-fowl, was now become a scene of veritable enchantment. The thick wood which lay behind the house had been transformed into shady groves and open glades for deer, whilst the front windows of the palace looked upon extensive flower-gardens, with a profusion of hothouses, summerhouses, arbours, and temples. The castle itself comprised a hundred and sixty-two apartments, splendidly decorated, and filled with costly collections of art. Even Eisenstadt itself paled before the beauty and magnificence of this new palace of Aladdin which the genie of wealth had raised on the dismal marsh.

The provision for music and acting was on a scale as elaborate as that of the rest of the palace. A splendid theatre, designed and equipped for the performance of operas and dramatic works, had been reared near the castle, and beside this stood a smaller theatre, fitted up for the marionette performances, to the perfecting of which the Prince had devoted much attention. The orchestra was reinforced by travelling players of eminence, whilst, in addition to singers especially engaged from Italy, various strolling companies were invited to give their services from time to time. It was an essential part of the scheme that this body of musicians and actors—temporary as well as permanent—should form one family, with Haydn as its head; but the appellation of 'Father Haydn,' by which the Capellmeister was known to the members of his orchestra, had its origin in an affection which owed nothing to discipline or arrangement. 'Friend, go back to the first allegro,' was the wording of a direction written by Haydn on the cover of one of his confrère's music-books, and it may be taken as an indication of the happy relations which existed between the chief of orchestra and his men.

A picture of the daily life at Esterház from spring to autumn would show a constant round of life in its fullest and gayest sense. Visitors poured in at its hospitable gates in an unbroken stream; and the strain upon those whose duty it was to provide amusement for the pleasure-seekers must have been enormous. If there was abundance of work, however, there was no lack of helpers, and thus Esterház became a little world in itself—a centre of music and acting, as well as an emporium of art treasures. Thither came the Empress Maria Theresa on a visit, and Haydn seized the opportunity of reminding her of the chastisement which she had ordered him to receive when, as a fair-haired chorister, he had clambered up the scaffolding-poles of the royal palace. 'Ah, well!' replied the Empress with a smile; 'you must see yourself, my dear Haydn, that the whipping has produced good fruit!'

Prince Nicolaus, though an excellent master, and one for whom Haydn entertained a deep affection, was, nevertheless, somewhat unreasonable in expecting his Capelle to share his devotion to Esterház as an almost continuous residence. The visits to Vienna were getting fewer and shorter—even the winter at Eisenstadt had been reduced to its shortest limits—and, admitting the attractions of the new palace as a summer residence, the musicians were pining to see their wives and families, and to breathe once more the air of the city. In 1772 the stay at Esterház was prolonged so far into the autumn that the musicians became impatient. The Prince had made no announcement of the date of his departure, and Haydn at length resolved to convey to his royal master a delicate hint of the orchestra's desire to be set free. He therefore announced the performance of what he called 'The Farewell Symphony'; and when the evening arrived, sixteen performers took their seats in the orchestra to carry out the Capellmeister's scheme, whilst the Prince, having no suspicion of what was intended, occupied his accustomed place. All went as usual until the last movement was reached, when one pair of performers rose from their chairs, extinguished their candles, and quietly left the orchestra. The music proceeded, and a little later a second pair arose, went through the same pantomime, and disappeared, the Prince watching their movements with a puzzled expression that almost destroyed the gravity of the rest of the performers. Pair after pair thus left the building, until at last only Tomasini (the Prince's favourite violinist) and Haydn remained. Finally, Tomasini blew out his candle, bowed to the Prince, and retreated, and as Haydn prepared to follow his example, the Prince's eyes were opened to their drift. Good-humouredly regarding the whole thing in the light of a joke, he exclaimed, 'If all go, we may as well go too!' and immediately quitting the theatre, he gave directions for the departure of the household.

We must pass over the years which intervened between the date of the 'Farewell Symphony' (the merits of which as a musical work must not be confused with the circumstances under which it was written), and the year 1790, when, to his great grief, Haydn lost the master to whom he had become so deeply attached. The Prince left Haydn a pension of one thousand florins, on condition that he retained his post as Capellmeister to the family. Prince Anton, however, who succeeded his brother, had no taste for music. The Capelle was practically disbanded, and though Haydn kept his official position, his constant presence at the palace was no longer necessary, and he took up his residence in Vienna.

Some three years before this event several attempts had been made by English musicians of eminence to induce him to come to London and play at the professional concerts, but he had resisted these offers with one and the same excuse—he could not leave the master whom he loved. On the last occasion Salomon, the well-known musician and concert-director, had dispatched a publisher named Bland to Esterház to endeavour to persuade Haydn to alter his mind. Bland was shown into a room adjoining that in which Haydn happened to be shaving, and whilst seated there he overheard the composer growling to himself over the bluntness of his razors. At length Bland caught the exclamation, 'Ach! I would give my best quartet for a good razor!' and without more ado, he rushed off to his lodgings and returned in a few minutes with a pair of razors, which he presented to Haydn. The Capellmeister accepted the gift with a smile, and rewarded the enterprising publisher with a copy of his latest quartet, which, later on, was produced in London, and has ever since been known by the title of the 'Rasirmesser' (Razor) quartet.

The death of Prince Nicolaus removed the only obstacle to Haydn's undertaking a journey to London; consequently, when one morning he found a visitor awaiting him at his house, who announced his business thus: 'My name is Salomon; I have come from London to fetch you; we will settle terms to-morrow,' Haydn regarded the matter as practically settled.
