That how it was in Puerto Rico, with little changes for winter. Up north where a lot of posters live, they are lucky if the high is 40 during the day. Here in Arizona during the summer, the days are 112 and nights are 92 degrees. But now in winter we don't have to deal with the snow and ice.
Yeah, you don't need to use your ears, just look at the chord but it's also good to train the ears as we grow older haha. This tune talks remind of my late father taught me how to tune a guitar and a ukelele. He was also the one watching big fights at home with his drinking buddies.
