Why is the EasyLead only in the key of C major and E minor pentatonic?
The key of C major was chosen because it’s the natural scale and the least confusing to learn. It’s also well positioned over the first 12 frets of the guitar to easily show you the various modes. And of course it also doubles as the A minor natural scale. The key of E minor pentatonic was chosen because it’s first most commonly known position for the pentatonic and is situated perfectly on the open frets. This will become very familiar to you and you can easily apply it to every other position. It also doubles as the G major pentatonic!
