To-morrow there is to be a concert at Herr Ployer's country-house in Dobling; Fräulein Babette is to play her new concerto in G, I the quintet [with wind instruments, in E flat major, 452 K.], and then both of us the grand sonata for two pianos [in D major, composed early in 1784, 448 K.]. I am to take Paesiello, who has been here since May on his return journey from St. Petersburg, in order that he may hear my compositions and my pupils.

No doubt the greater number of his pupils either—like Fräulein Aumhammer—cared more for social intercourse with Mozart than for actual instruction, or took lessons for a short time only that they might be able to speak of the great performer as their teacher. The celebrated physician, Jos. Frank, relates that he took twelve lessons from him in 1790:[ 30 ]

I found Mozart a little man with a large head and plump hand, and was somewhat coldly received by him. "Now," said he, "play me something." I played a fantasia of his own composition. "Not bad," said he, to my great astonishment; "but now listen to me play it." It was a miracle! The piano became another instrument under his hands. It was strengthened by a second piano, which served him as a pedal.[ 31 ] Mozart then made some remarks as to the way in which I should perform the fantasia. I was fortunate enough to understand him. "Do MARRIED LIFE. you play any other pieces of my composition?" "Yes," answered I; "your variations on the theme 'Unser dummer Pobel meint' (455 K.), and a sonata with accompaniments for violin and violoncello." "Good!

I will play you that piece; you will profit more by hearing me than by playing them yourself."

It is plain that he had the tact and skill to manage even such pupils as these. He treated those who had the power and the wish to become true artists under his guidance in quite another fashion, and they profited not only by his regular instruction, but still more by his encouragement and incitement to exertion.

Johann Nepomuk Hummel came to Vienna in 1785, with his father, who afterwards undertook the conductorship of the opera, under Schikaneder; at seven years of age the young Hummel already created great expectations by his clavier-playing. A pupil of Mozart's, named Freystädter, brought Hummel to him in 1797; the boy played one of the easier sonatas (with which Mozart had no fault to find, except as to the hurried tempo), and then one of his newest concertos by heart.[ 32 ] Thereupon Mozart decided to undertake Hummel's instruction, but only on condition that he resided with them altogether. We are not told how often or with what regularity he received lessons; but he heard Mozart play, and had to play over to him any clavier music that came into the house. One evening Mozart returned late from some entertainment with his wife, and found a piece of music which he was curious to hear. Young Hummel, who had been awaiting their return, had lain down on a couple of chairs and fallen asleep. "Stanzerl," said Mozart, to his wife; "wake Hans, and give him a glass of wine." No sooner said than done; and the boy played the new piece of music, late at night as it was.[ 33 ]

Mozart's musical instruction was sure to be desultory. Freystädter relates that he generally received Mozart's directions and corrections of his musical exercises sitting at a side-table, while a game of bowls was going on.[ 34 ] Attwood MOZART'S LESSONS IN THEORY.

also tells us that Mozart sometimes persuaded him to join in a game of billiards instead of taking a lesson.[ 35 ] The pupils did not consider their master guilty of caprice and neglect; but felt themselves spurred to activity by their intercourse with him.

Mozart took young Hummel everywhere with him, made him play, played duets with him, and declared that the boy would soon excel himself as a pianist. Hummel was greatly attached to Mozart, both then and ever after; he remained in his house for two years, until in November, 1788, his father set out with him on a professional tour.

Mozart also gave lessons in the theory of music, sometimes even to ladies; we hear of a cousin of the Abbé Stadler as Mozart's pupil in thorough-bass. The exercise-book which he used for instruction in thorough-bass in 1784 is now in the Imperial library at Vienna.[ 36 ] Mozart wrote down a very characteristic melody, or a bass, or both, which the pupil was to arrange in several parts; then Mozart corrected the passage with short remarks on the various mistakes, alternately Italian or German, sometimes of a comic nature—for instance: "Ho l' onore di dirla, che lei ha fatta la scioc-cagine (da par Suo) di far due ottave tra il 2do Violino ed il Basso"; or in German: "This E is very forced here; it shows that it has only been put in to prevent too rapid a passage from one consonance to another—just as bad poets often do stupid things for the sake of rhyme. You might have gone gradually from C to D very prettily by inserting thirds." These remarks are purely grammatical; and it is evident that Mozart's teaching was of the good old-fashioned kind, which strives first to give the pupil a thorough knowledge of the grammar of his art. From exercise-books of this kind, of which Zelter saw one in Vienna,[ 37 ] a little MARRIED LIFE. handbook of thorough-bass was afterwards printed under Mozart's name, and was much in use for some time.[ 38 ] With more advanced pupils he naturally proceeded differently. Attwood preserved an exercise-book with compositions, which he had submitted to Mozart shortly after his arrival in Vienna. Mozart had crossed out whole passages, and rewritten them with the remark, "I should have done this so."[ 39 ] When Kelly, the tenor, who made pretty little songs which Mozart admired, imagined that he could make himself into a serious composer by means of studies in counterpoint, Mozart said to him, "If you had studied counterpoint long ago in Naples, you would have done well; now that you have to give your mind to your education as a singer, you will make nothing of it. Remember that half-knowledge is a dangerous thing. You have considerable talent in the invention of melodies; a smattering of theory would ruin that, and you can always find some musician who can help you when you want it. Melody is the essence of music. I should compare one who invents melodies to a noble racehorse, and a mere contrapuntist to a hired post hack. So let it alone; and remember the old Italian proverb 'Chi sa più, meno sa.'"[ 40 ]
