| Gakuko was conducted changing the musical notes for each of its sessions with one note on one day in order of Ichikotsu-cho note, Hyo-jo note, So-jo note, Oshiki-cho note, and Banshiki-cho note (after the Tenpo era, Taishiki-cho note was also included). |
楽講は、各回で調子を変えながら、壱越調・平調・双調・黄鐘調・盤渉調（天保以後は太食調も）の順に日を改めながら行われた。 |
