Watch the Orientation online guitar lesson by Annie Raines from Blues Harmonica Blueprint
If you are already comfortable with the basics of harmonica playing, feel free to skip over the beginner lessons, but I recommend you watch this segment for an explanation of the "Time-Dot" tab, and the segment titled "The Layout" so you’ll be familiar with the visual systems we’ll be using at various points throughout the course. And if you’re not familiar with music theory, don’t worry. Some of the greatest blues harp players of all time couldn’t read music. There’s a little theory here and there to help you get familiar with basic terms.
About the tab: The tab borrows from the SuperTAB font created and developed by Steve Jennings and Pat Missin. There is no uniform standard of notation for harmonica. Some people use letters or up and down arrows to denote blow and draw notes. I prefer to use plain numbers for blow notes and circled numbers for draw, saving the arrows for actions relating to bending and other effects. In developing this tab I have tried to pay attention to nuance while keeping it simple and visually intuitive. I came up with the "Time-dot" system so you can see the music the same way you hear it: with a beat.
