SLOWLY start to tune the guitar starting from the thickest string and going to the thinnest string.

Make sure to take your time while tuning. You just went through the effort of replacing your strings, and you don't want them to break!

Standard tuning is Open E, and the notes for each string in order from thickest to thinnest is "E A D G B E." A memory trick for this is "Eddie Ate Dynamite, Good Bye Eddie."
