I hope the title is phrased well.
This week, being Shabbat Shira, we read Az Yashir ("Song by the sea"). I have been laining this for many years. There are certain verses that are read with a special "Shira tune" while the rest is read using the normal trope tune / mode.
Has someone published a list of which verses should be read with this special tune? I'm unaware of seeing this list somewhere, but I guess this may be around.
