Five years later another accomplished German music teacher appeared upon the scene, whose modest advertisement is a relief after reading the previous effusion. This man confines himself to the German flute, which seems to have been an instrument of some importance at that period. This notice runs as follows: “This is to inform the Public, “That an Evening School for teaching young Gentlemen to play upon the German Flute will be opened by the Subscriber ... where young Gentlemen may be taught, by an easy and regular Method, to play with Judgement and Taste, for the moderate Price of Six Shillings per Week, and Thirty Shillings Entrance Money, provided the Subscriber can procure six Scholars. The Hours of Attendance will be every Evening (Sundays excepted.) from 6 to 8 o’clock. Said Subscriber will also attend Gentlemen at their Houses, one Hour every other Day, for one Guinea per Month and Thirty Shillings Entrance. John Stadler. N. B. If any Gentleman is desirious to know the character and abilities of said Subscriber as a Teacher of Music, they may be satisfied by enquiring of any Gentleman in this City, who is a Judge of these Matters.”[125] It is to be noted that Stadler opened a _school_ for his instrument, which emphasizes the popularity which this instrument must have enjoyed. Two years later another German flutist, George Isenberg or D’E’issenburg[126] increased the force of teachers in Philadelphia. Again we find in 1774 Peter Kalckoffer advertising to teach the beloved German flute as well as the Latin tongue.[127] Probably the most important of these German musicians was H. B. Victor, who went from Germany to London, in 1759,[128] and whose advertisement appears in 1774--an advertisement worthy to be placed alongside of some of those of the present day. He seems to have been an inventor of musical instruments as well. The number of instruments he plays at once, remind us of some of the street musicians of the present day. “Mr. Victor, Musician to her late Royal Highness the Princess of Wales, and Organist at St. Georges in London, lately arrived here, takes this method of acquainting the Musical Gentry in general, that he gives instructions on the Harpsichord, or Forte Piano, Violin, German Flute, etc., especially in the thorough Bass both in theory and practice, for that his pupils may soon come to a fundamental knowledge of that fine science.
