Most people don't live near me, which is why I teach online. I use Skype to do this. Skype doesn't treat the guitar as background noise to eliminate; it's free; and it retains an accurate record of past lessons, text dialogue, etc.
You'll need a tried and tested Skype account to get started. It is also very helpful to use a laptop, since you can easily switch between face view and guitar view. (It's always nice to begin a lesson face to face!) It's also helpful if the laptop is at about head height, facilitating a slight bird's-eye-view when you tilt the screen towards the guitar, enabling me to see where your fingertips terminate on the fretboard.
Please refrain from positioning yourself so that your back is to the strongest light source in the room, as that will serve to turn you into a silhouette from my perspective.
Please avoid using a tablet. The small screen requires you to sit close, thereby cutting at least one end of the guitar out of view (I need to be able to see everything from your picking arm elbow to the headstock of your guitar for the most part of the lesson.). A tablet will allow for nothing but a worm's-eye-view (unless you use some special stand I suppose), obscuring the view of your fingertips, so that I cannot see which notes you're attempting to play.
Let's talk about timezones: I live in the UK, and so I rest and rise according to Greenwich meantime, so just bear that in mind when you consider a time for a lesson with me, it'll have to be a time during which I intend to be awake. Sorry!
