the refrain is used as a congregational response, but in most Ashkenazic Orthodox synagogues it is sung by everyone together to any of a large number of tunes. This includes the Orthodox Synagogues who employ this element and Synagogues under the Modern-Orthodox umbrella. Old German and Polish melodies At certain periods of the year many northern congregations discard later compositions in favor of two simple older melodies singularly reminiscent of the folk-song of northern Europe in the century succeeding that in which the verses were written. The better known of these is an air, reserved for the Omer weeks between Passover and Shavuot, which has been variously described, because of certain of its phrases, as an adaptation of the famous political song "Lillibullero" and of the cavatina in the beginning of Mozart's "Nozze di Figaro." But resemblances to German folk-song of the end of the seventeenth century may be found generally throughout the melody. Less widely utilized in the present day is the special air traditional for the "Three Weeks" preceding Tisha b'Av, although this is characterized by much tender charm absent from the melody of Eli Tziyyon, which more often takes its place. But it was once very generally sung in the northern congregations of Europe; and a variant was chosen by Benedetto Marcello for his rendition of Psalm xix. in his "Estro Poetico-Armonico" or "Parafrasi Sopra li Salmi" (Venice, 1724), where it is quoted as an air of the German Jews. Cantor Eduard Birnbaum ("Der Jüdische Kantor", 1883, p. 349) has discovered the source of this melody in a Polish folk-song, "Wezm ja Kontusz, Wezm", given in Oskar Kolberg's "Piesni Ludu Polskiego" (Warsaw, 1857). An old melody, of similarly obvious folk-song origin, was favored in the London Jewry a century ago, and was sung in two slightly divergent forms in the old city synagogues. Both of these forms are given by Isaac Nathan in his setting of Byron's "Hebrew Melodies" (London, 1815), where they constitute the air selected for "She Walks in Beauty", the first verses in the series. The melody has since fallen out of use in English congregations and elsewhere. Text The full version of the song (note that many Reform congregations omit verses 3, 4, 6, 7 and 8 which make reference to messianic redemption), while Sephardic congregations based in the Jerusalem and Aleppo rites omit verse 4 and verses 6 through 8, as they
