We're also heavily involved in updated every lesson to include HI-Def videos.
In the process, some of us are completely re-writing lessons to make them easier to understand.

As far as the later lessons are concerned where you get into the intermediate and advanced stuff... it's harder to come up with static lesson plans because every student is different and may want to go in different directions.

While there'll always be structured plans in place, we'll still be keeping the thousands of random lessons aimed at teaching various tricks of the trade and little riffs that can usually take years to learn.

The advantage there is you can take a unique riff or original song from an instructor and then apply the things you're learning to your own songs.

I know with my own lessons, I don't delve into theory as much as some of the other instructors and tend to try and explain what I'm doing in simple language that anyone can understand. (quite a few of the emails I get praise the fact that I don't ramble on with a lot of gobbledy gook theory that just tends to confuse them)

For instance just learning something like this end of song lead:

(Which I'll be redoing in Hi-Def soon along with an expanded lesson)


... can be used in just about any song in the key of E... either at the beginning or end of the song.
And rather than get into the intricate details of theory or what scales I'm using, I'll be just showing how to play it slowly at first using visual examples. Then posting a song where it's been used as an example.
However, the transcription is always available for those who prefer to read music or tabs.
