Whether you are a beginner or a professional the first and most vital thing to do before playing the guitar is to check the tone. If it is not right then you have to adjust it until it sounds right and pleasing to the ears.
But sometimes we are just having a hard time tuning it or adjusting it.
You have to twist and pluck and adjust, then twist, strung, and adjust again. It is a tedious repetitive process until you are satisfied. And it may take a long time before you are even able to play.
