Musicians struggle to understand and apply music notation conventions, leading to confusion when reading scores

Musicians and music students frequently encounter confusion about fundamental music notation rules, such as why time signatures don't need to repeat on every line of a score. This knowledge gap forces them to search online for answers, indicating that music education materials and teachers aren't adequately explaining these conventions upfront. Current solutions (scattered Stack Exchange answers, inconsistent textbooks) fail to provide clear, authoritative guidance that prevents this confusion from occurring in the first place.
