sheet-music

Law 8c part-of test on the defined sense. Pinned sense: the time-signature as inscribed at the head of the score — its accepted definition's own persistence mechanism is 'written notation — time-signatures are inscribed', a notational convention of two stacked numbers drawn on the staff. Sheet-music's accepted definition carves the document as 'marks — staves, notes, clefs, dynamic and articulation marks, and text' following 'the shared syntactic rules of musical notation (staves, clefs, note values, dynamics)'; the time-signature is precisely the mark that fixes the beat structure within those rules. When inscribed, it is literally ink within the artifact — a part of the document, in the same constituent-mark family as the accepted sheet-music CONTAINS staff/note/rest. Asymmetric: remove the sheet and this instance of the time-signature is gone; the convention operates on other sheets.

Sheet music as a document bearing a musical score is composed of notes as its atomic notational content. Removing notes from the document leaves a frame with no content — the page stops operating as sheet music for a work. Removing the document does not stop note operating as a notational unit elsewhere. Asymmetric part-of. Direction whole -> part.

Law 8c part-of test: sheet music as a human-made document bearing a musical score is composed of barline marks as its temporal-structure boundaries. Removing barlines from the document leaves a score whose measures cannot be visually delimited — the page stops operating as a readable musical score (the time signature's promise is invisible). Removing the document does not stop the barline operating as a notational mark elsewhere. Asymmetric part-of. Direction: whole (sheet-music) -> part (barline). Barlines are structural elements of standard notation scores referenced in the sheet-music definition's notation-system parameter.

Law 8c part-of test: sheet music as a human-made document bearing a musical score is composed of fermata glyphs as its suspension marks. Removing fermata from the document leaves a score that cannot carry the composer's intended pauses — the page stops operating as a complete musical score (it would be missing notated suspensions). Removing the document does not stop the fermata operating as a notational glyph elsewhere. Asymmetric part-of. Direction: whole (sheet-music) -> part (fermata). The fermata is explicitly named in the sheet-music definition among 'dynamic and articulation marks' that compose the score.

Sheet music as a document bearing a musical score is composed of rests as its notated silence material. Removing rests from the document leaves a score that cannot complete its rhythmic structure — the page stops operating as a complete musical score. Removing the document does not stop rest operating as a notational glyph elsewhere. Asymmetric part-of. Direction whole -> part.

sheet music as a document type contains bars as structural units — a bar (measure) is a constituent element of a sheet music document's layout. Law 10 CONTAINS: whole contains part.

Law 8c part-of test on the defined sense: sheet-music's accepted definition names the document's constituent marks explicitly — 'staves, notes, clefs, dynamic and articulation marks, and text — encode a musical work'. A clef, per its accepted definition, is 'a standardized notational glyph placed at the beginning of a musical staff' — literally ink on the page, a mark within the artifact. Pinned sense: the clef as an inscribed glyph of the printed score. Same constituent-mark family as the already-accepted sheet-music CONTAINS staff, note, and rest. Asymmetric: removing the document removes this clef's instance; the clef as a glyph operates on other sheets. Whole (sheet-music) -> part (clef).

Law 8c part-of test: sheet music as a human-made document bearing a musical score is composed of staves as its structural frame. Removing staff from the document leaves a page with no notation frame — the score cannot be read as music, the document stops operating as sheet music. Removing the document does not stop staff operating as a notational structure in other contexts. Asymmetric part-of. Direction: whole (sheet-music) -> part (staff).

SERVES test (Law 8d) — for whose sake is it built: the music-stand definition pins the beneficiary explicitly: 'a support fixture shaped to the held-object class sheet music', with surface width 'matching a full folio' and a page-holding mechanism that keeps pages down under performer movement. The servant was manufactured for the sake of the held object, and the reciprocal definition confirms: sheet music 'persists as a product category, the designed held-object of the music stand'. Not DEPENDS_ON: remove sheet music and the stand still operates as a stand (it holds whatever is placed on it — the removal test fails both ways), so this is purpose, and purpose files SERVES, never DEPENDS_ON (Laws 8c/8d). Servant points at master: music-stand -> sheet-music.
