"Now, my friends," said Mrs. Martin, as she gathered a knot of young people about her on the breezy veranda of her pleasant country house, one moonlight evening in September, "we have had picnics, and drives, and walks, and rows upon the lake in the daytime, and dances almost every night since you have been visiting me, and I believe that you may be getting sufficiently tired of these sports, as the weather grows cooler, to wish to change about and settle down to something at once more instructive and more artistic. You are, all of you, students of music--Ethel reads it very well at sight, Kenneth plays the 'cello, Patty plays the violin, Beatrice sings charmingly and plays accompaniments, besides being a general helper and strong inducer of merriment, while the rest of you have good voices, very pretty taste, and some knowledge of music. So I am going to organize a musical club, which shall meet here regularly once a week after you leave me, having finished your visits. And I am going now to attempt to explain to you so thoroughly the best methods of getting up a 'musical' that other boys and girls who wish to amuse themselves in the same way may learn from your example. A great deal of fun may be had from the preliminary practice and rehearsals. I should advise you to form, in the first place, three quartets: one of mixed voices--that is, you know, soprano, alto, tenor, and bass--besides one of male voices, first tenor, second tenor, first bass (or barytone), and second bass. Then a quartet of female voices--two sopranos and two altos, and this last can sometimes do trios as well as quartets. For all of these different sets of voices the most beautiful and pleasing music has been made. Mendelssohn's collection for mixed voices, called 'Open-Air Music,' is intended to be done without accompaniment, which, as you see, fits it to be sung independently in any place--in the woods, or on the lake, or while driving. It is as full of inspiration and of the true sweet Mendelssohnian melody as anything that ever dropped from the pen of that sociable and amiable composer; the harmonies are delicious, and the words are full of the poetry of land and sea and love. For male voices there is a large literature; but perhaps the heaviest mass of writing is found in compositions for women's voices, either in the form of duets--as, for instance, those of Abt, Mendelssohn, Rubinstein, or Dvorák--in trios, and in quartets.
