I’m reading the first theory book using a desktop browser at the end of section 1.3 there is a graphic that shows the chords of the twelve keys. It says to swipe the carousel to see the chords. I don’t have a swipe function on the desktop and can see there are twelve dots across the bottom of the graphic. However the graphic doesn’t change when I click on the different dots to move through the carousel. I’ve tried Firefox and Safari.
Sorry it’s not more obvious. If you click and drag with the mouse it will scroll over to the next graphic. Agree it’s somewhat a somewhat awkward maneuver compared to swiping with a finger.
