行

kaishi no gyō ga nagai to, uta ga muzukashii

The lines of the lyrics are long, so the song is difficult.

gyō no saisho ni, ten o uつ

You add a dot at the end of a line.

kono gyō no kanji no yomikata ga wakarazu, jisho de shirabeta.

I didn't know how to read the kanji in this line, so I looked it up in the dictionary.
