Around Jogan era (Japan), among these songs described above were collected into a book, then Masanobu ICHIJO chose scores around 920 (one theory says that FUJIWARA no Tadafusa wrote scores), and later on, songs were brought down by the To and Gen families. 上に述べたような歌謡が貞観 (日本)年間ころにひとつの書物にまとめられ、ついで、一条雅信によって延喜20年ころ撰譜され(一説に藤原忠房によって作譜されるという)、以後、藤家および源家によって歌曲はつたえられた。 |
