Musicians and music theorists struggle to interpret ambiguous historical notation rules about accidentals in ornaments

Music students, composers, and performers encounter confusing historical music theory texts (like Gould's work) that use unclear language about when accidentals should be applied to ornamental notes. Without clear guidance, they waste time researching, debating interpretations, or making incorrect musical decisions that affect performance quality and academic credibility. Current music theory resources don't adequately clarify these edge cases in historical notation conventions.
