[ Предположительная тональность: D ] The intro should be done using NATURAL HARMONICS like this.. E|----12-----5----------------12------5----| B|-12------5---------------12-------5------| G|-------------12------------------------5-| D|-----------------------------------------| A|-----------------------------------------| E|-----------------------------------------| ~ pretty wild vibrato - since this is a harmonic on an open string you need to use a vibrato arm (or if your guitar does not have one you can do this by applying pressure to the string above the nut - but this is harder to control)
