<human>:  I recently started playing the guitar and was wondering if there's a standard way to tune it?
<bot>: Yes, there is a standard way to tune a guitar. Generally, the six strings of a guitar are tuned to the notes of E, A, D, G, B, and E (from thickest to thinnest string). There is also an alternative tuning, known as the drop D tuning, where the sixth string is lowered a full step. This tuning can be used for some types of music, such as blues and rock. Experienced guitar players may also use alternate tunings to create various effects.
