These music books are great for teachers to use in music classes. You can use them to plan lessons throughout the year or explore music across different regions. When handling the books, be gentle as they are old and the covers and pages may be a bit fragile. To keep them in good shape, store them in a dry and cool place. Avoid exposing them to direct sunlight for long periods as it can further fade the pages. If you notice any dust, you can gently wipe the covers and pages with a soft, dry cloth.
