How can I effectively tune my 3/4 guitar using a guitar tuner?

To effectively tune your 3/4 guitar using a guitar tuner, start by turning on the tuner and plucking each string one at a time. Match the pitch of each string to the corresponding note on the tuner display. Adjust the tuning pegs until the tuner shows that the string is in tune. Repeat this process for each string until all strings are tuned correctly.
