The document discusses several key conventions of music magazines, including the masthead, banner, lead, cover lines, and main image. The masthead displays the magazine's name and logo and can indicate its genre through color. The banner uses large black text on a white background to catch readers' eyes. The lead is an introductory paragraph summarizing the main article. Cover lines are side headings highlighting smaller stories to generate interest in the main piece. The main image on the cover depicts and advertises the primary focus of the issue.
