Half-Notes
Half-notes can be made by adjusting the amount of water, which can be colored accordingly; but for an ordinary entertainment the octave will be found quite sufficient, and at any rate to begin with, will require all the musician’s attention. When he can play quickly and correctly with his first eight glasses, he can introduce half-notes, but it is very unwise to start with too many vessels, for it will give both him and his audience far greater satisfaction to hear eight glasses played well than to hear a larger number played indifferently.
An important point to remember is to keep the finger and the rim thoroughly wet. If this be borne in mind, the notes will come much more easily and clearly, whilst the disagreeable droning sound will entirely disappear. Care must also be taken to see that the glasses are steady on their bases, as, in the case of champagne glasses, especially, they are liable to tip up under the pressure of the finger.
With regard to the music suitable to musical glasses, it has already been mentioned that Gluck and Mozart composed songs for this class of performance, but the beginner is not recommended to attempt these until he is very skillful. As some time will elapse before he can play even the scale with ease, perfectly simple music should be all that he tries to learn at first. When such easy, although somewhat hackneyed, pieces as “The Blue Bells of Scotland” and “Annie Laurie” have been mastered, he can try more advanced works.

Many attempts have been made to discover some means of producing the sound other than by rubbing the finger over the rim of the glass. Violin bows and other similar contrivances have all proved ineffectual.
It would seem that the texture and surface of the human skin are alone suitable for this purpose, and nothing else has proved successful. This is the reason why musical glasses have not become more common, for the continual rubbing of the wet finger over the surface of the glass becomes after a time somewhat unpleasant. However, this hardly applies to the short period that an ordinary performer would devote to an entertainment. Yet such was the reason that caused the failure of Franklin’s instrument.
The following few bars of music, being the opening phrases of a well-known song, will prove very suitable for glass music, especially when played at the dinner-table after the dessert has been discussed. To simplify the matter for those who are not familiar with the usual notation of music, the notes are given by name, thus enabling any one to pick them out with ease:
E, E, E, F, F, G, F, E, D, E, F, G, C, F, E, D, C.
