It is amazing what a key can do for the songs you play: Change the key and it can make the song very different.
Changing key on the guitar is relatively easy: You can use the same chord shapes and simply use a capo to move the shapes up-or down the fret board.
Certain well-known songs are often played in the same key, by changing the key of the song you can give them a fresh feeling. Try it!!
Good luck and hope to catch you soon again,
