Template Lesson Files are purely for your use.
Download them at any time, and make sure you choose the format most suited to your needs.
There are three formats used:
TAB and Stave Lesson Files are probably familiar and self-explanatory. That said, for TAB, remember that the bottom line is the bottom string and the top line is the top string. On the guitar, the low sounding string is the bottom string. The high sounding string is the top string.
"BLANK NECK" means that there are no dot markers on the diagram. "NECK" means the fretboard lesson file will have dot markers. If you are creating generic patterns then use BLANK NECK, otherwise, if you want to reference a cerain key, use NECK.
03X24 means that there are 3 blocks, and each block has 24 frets.
