Page "Pop'n Music" Paragraph 33

Unlike most of Konami's Bemani series, the Pop ' n Music interface is not designed to represent any actual musical instrument.

Instead, it uses nine buttons, each three-and-a-half-inches in diameter, laid out in two rows.

Five buttons are the bottom row, the other four being the top.

Like in most Bemani games, color-coded notes ( in this game called " Pop-kun " ( ポップ君 ) and anthropomorphized with faces ) fall from the top of the screen in nine columns that correspond to the buttons.

When a note reaches the red line at the bottom of the screen, the player presses the button, which triggers a sound within the song.
