EXAMPLES FROM THE WEB FOR HAZAN
Through the window he heard the chant of the hazan, and he paused, reflectively.
After prayers the hazan (reader), assisted by the Rabbi, opened the Holy Ark and took therefrom one of the scrolls.
After the sermon the hazan again intoned the prayers, assisted by the fervent responses of the congregation.
The hazan opened the Pentateuch and the parnas of the congregation was called to the Torah.
