Human: I've recently started playing the guitar and would like to know if there's a standard way to tune it? Assistant: 
Yes, there is. There are several ways to tune a guitar, but one of the most common methods is called "drop tuning" or "drop D". In drop tuning, you start with the strings tuned to the first four frets of the guitar (e.g., E-A-D-G), then you move each string down one full step (i.e., from E to A, then from A to D, etc.). This creates a lower tension on the strings which makes them easier to play.
