Maqam Sigah, from the Persian for "third place", is applied when there are special Torah readings. This maqam is usually used for the weekday prayers as well as the Syrian way of chanting the Torah with the cantillations. This maqam is also used on the first days of the Shalosh Regalim (holidays) and parashiot relating to Menorah, Kohanim, and the building of the mishkan. In addition to that, there is an entire selection of pizmonim that are related to Purim that come from this Maqam, and that is why this maqam is used the Shabbat prior to Purim (Shabbat Zachor). Sigah is used for the following Shabbats and for the following reasons: Miketzh is always the Shabbat during Hannukah- a holiday that is associated with the Menorah. Tzaveh discusses the clothing and ornaments of the Kohen HaGadol in the mishkan. Eimor discusses the laws pertaining to the Kohanim, as well as the laws of the holidays. Behaalotecha mentions the Menorah in the beginning of the parasha. Ki Tavoh discusses the reading of the Torah when entering the new land.
