On Shabbat Ki Tisa (Exodus 30:11- 34:35), we read about the sad episode of the Golden Calf. Therefore, the morning prayers are conducted in Maqam HIJAZ, according to all Aleppo sources, and Maqam SABA according to all Damascus sources. Damascus custom is apply SABA to indicate a mood of pain, and to only apply Maqam Hijaz for extreme sadness, such as Shabbat Ekha; when we mourn over the Bet Hamiqdash. Gabriel A Shrem used to mix Maqam BAYAT with HIJAZ in order to dilute the sadness of the maqam.
