In the teachings of the early authorities, we find special languages regarding the recitation of the Haggadah. The Ritva wrote (Hilchot Seder HaHaggadah, page 11): "A person must say the Haggadah with pleasantness and in a loud voice with all his might." And in the Shibbolei HaLeket (Siman 288), it is written: "And we say the Haggadah with praise, with song, and with calmness, as we find with our ancestors, as it is said (Isaiah 30:29), 'The song will be for you as in the night when a festival is kept.'" And we find a similar language in the words of the author (Shulchan Aruch Orach Chayim Siman 487, Seif 4) regarding the manner of reciting Hallel on the first night of Passover, where it is written: "On the first night of Passover, we conclude the Hallel in the congregation with pleasantness, with a blessing at the beginning and the end." He emphasized adding and writing with pleasantness, which was not written anywhere else regarding the recitation of Hallel, implying specifically that on the night of Passover, there is an aspect of reading the Hallel with pleasantness.

Indeed, we find this distinction in the words of our teacher, Rabbi Hai Gaon, who wrote that we do not recite a blessing on the reading of the Hallel on the nights of Passover, "for we do not read it in the Torah-reading manner but in the manner of one who recites a song." It implies that the manner of reciting the Hallel on the night of Passover is like reciting a song. There is a need for clarification of the definition in this matter, as well as why this recitation of the Hallel differs from other recitations of the Hallel.

Thus, we see from the words of the early authorities that it is not enough to recount the Exodus from Egypt with deep thoughts or interpretations, but we also need to recount it with song and pleasantness. Also, it is necessary to recite the Hallel on the night of Passover in the synagogue and at home during the Seder. There is a need for clarification of the source for all of this and what is the foundation and root of this law.
