教授要領
A 1914 Japanese teaching manual compiled by the Gifu Prefectural Normal School elementary affiliate and published by Nakano Yasugoro, aimed at schoolteachers. Its single picture shows three vertical staves of hand-drawn musical notation, with treble clefs at the top and small notes and rests set on ruled lines against a grey paper ground. A designer might take from it the rhythm of repeated vertical lines and the stacked, columnar layout of notes as a graphic motif.
