Really cool stuff- sounds from super Mario video game

Hello all of you. Today I’ll show you really cool and easy stuff to play on your guitar.
If you remember a very popular video game in erstwhile called "Super Mario" then you
remember the sound effect when Mario inserts the key into the lock. I’ll show you how do play it on guitar, it's really easy to play, even for a total beginner. All you need do to is press lower and upper E note on your guitar in 3rd fret. You can do it either with one finger like you do in barre chords or by using your 1st and 4th finger. If your finger is in position then pull lower and upper E string at the same time and slide your hand to the 12th fret.
Very easy, isn't it.
