I have produced a bmp to scale showing the A4, a typical music book page and a 16 x 9 tablet. This will indicate the wide screen issue. You can use something like Muse Score to write a score anew, or cut/paste extra rows of music to fill the page, something I do for those songs I want to polish, other than getting a tablet with a 4 x 3 ratio. (which fits the 9 x 12 page perfectly)

Thank you very much maintech, your images are very clear and let me understand (finally) the real difference between a 16:9 (16:10) screen size vs 4:3 (3:2).

Best regards, Roberto.
