Az Yashir Moshe (Rasd/Hijaz) - אז ישיר משה (רצד חגאז)

This melody of Az Yashir Moshe is divided into 3 parts:

1. RASD - Dodi Yarad Legano of Parashat Zachor
2. PETIHA - zidane
3. HIJAZ - same tune of Letzur Goalenu for Pesah

I always sing this "shira" on Shabbat Zachor as well as the first day Yom Tov for Pesah and Sukkot. There are times I sing it on other Shabbatot as well.
