musical intonation marks
Refers to notation marks used in traditional Japanese music (especially for instruments like the shakuhachi) to indicate pitch inflection, ornamentation, or phrasing. A specialized term; not used in everyday conversation.
The shakuhachi score has detailed intonation marks written in.
Compound of 節 (fushi, 'melody, tune, phrase') and 博士 (hakase, 'expert, master; also used historically for notation marks in gagaku'). The exact historical derivation is uncertain, but the term is conventionally associated with traditional Japanese music notation.
