Welcome to Swampville. A new knowledgebase for the guitar. You can enter this site and its features in different ways and different levels. In developing your skills it is very important you set a certain purpose for yourself. 

At the time you will reach this purpose and understand its complete excercises, move on to the next excercise; which part of your guitar playing and/or knowledge needs more attention? Study the appropriate theory/excercises accordingly AND meticulously. Of course you can study more than one thing at a time, especially if the excercises are related to one another. Find out how it works for you, practise makes perfect.....

I think there is no real rule of thumb for playing any instrument, other than that it is very important to master some basic skills, but if something just sounds good, it just sounds good...

Use this site as your additional reference, and of course not everything is described here but this site features the most common musical theory and  excercises which will allow you to make a big difference in improving your musical abilities.  You can leave a message if you have any questions and/or suggestions.

Have fun!
