If you thought we'd give up after Part I...you're probably right But, it's a useful skill and easy enough to get a high level overview of...so in the interest of learning, here's Part II
Last month we learned the notes on the lines of the staff (Every Good Boy Does Fine, low to high), and the notes in the spaces (FACE). We also met the quarter-note (solid head with a stem, one note per beat). This month, we’re going to learn about sharps and flats—which give us the notes in between the notes we read last month—as well as notes above and below the staff. We’re also going to introduce eighth-notes (solid heads with stems that are connected by a beam, two notes per beat)
