In this lesson we will learn how to check the guitar to make sure it is in good, playable condition. If a guitar is out of adjustment in any way, it will cause one to struggle unnecessarily when trying to play it.
The height of the strings - how far they are from the fingerboard, is referred to as the "action". If the guitars action is low - close to the fretboard - the guitar will be easy to play, but the sound will not be very loud and the string might buzz against the frets. On the other hand, if the action is high, the guitar will have a much louder tone and won't buzz, but the fingers will wear out much faster from having to push the strings further and harder.
