<human>:  How do you play a way on the guitar?
<bot>: To play a song on the guitar, start by learning the notes for the chords and scales that you will need to play the song. Next, practice the chords and scales until you are comfortable and can play them without thinking. Once you know the chord positions and fingerings, practice strumming and changing between chords smoothly. Finally, practice playing the song slowly to ensure that you are playing the notes correctly and can transition between parts easily. Once you are comfortable playing the song, you can gradually increase the speed and practice the song until you have mastered it.
