Danzi, Franz Ignaz (1763-1826) was a German composer. His works are not so popular. Only his wind quintets are know among woodwind players. He revered W. A. Mozart, and arranged "Die Zauberflöte" for string quartets. A set of the part notes was published by M. Falter, Munich around 1800. His arrangement consists of 17 pieces as follows. No.1, "Hm! Hm! Hm! Hm!" No.2, "Zum Leiden bin ich auserkoren" No.3, "Schnelle Füsse rascher Mut" No.4, "Es lebe Sarastro Sarastro lebe!" No.5, "Herr ich bin zwar Verbrecherin" No.6, "Wenn tugend und gerechtigkeit" No.7, "Wie? wie? wie?" No.8, "O Isis und Osiris" No.9, "Bald prengt den Morgen zu verkünden" No.10, "Der, welcher wandert diese Straße voll Beschwerden" No.11, "Tamino mein!" No.12, "Wir wandelten durch Feuersgluten" No.13, "Papagena! Papagena! Weibchen! Täubchen!" No.14, "Klinget, Glockchen, klinget!" No.15, "Pa-Pa-Pa-Papageno" No.16, "Nur stille! stille!" No.17, "Heil sei euch Geweihten" The arrangement was very faithful to the original, and is valuable in that players could enjoy the wonderful music as a chamber music. We first made the transcript of the sheet music published by M. Falter, and combined them to make scores. The scores show some discrepancies, which are usual in such old music notes, and was revised to obtain unified styles and articulations. In the revising, we referred the original score by Mozart. No.9, "Bald prengt den Morgen zu verkünden" is a quartet for three boys and Pamina. Pamina is despairing because she Tamino spoke nothing to her. She has suicidal thoughts. Three boys restrain her, and tell her that Tamino loves her. In the measures from No. 40 to 42, and from No. 60 to 64, the sheet music published by M. Falter around 1800 has only accompaniment parts. The voice parts are missing. It must be some mistake. We rearranged the error parts following Danzi's way of arrangements to restore the voice notes.
