Slurs on Inside Strings
When slurring is between notes on the inside strings, in most cases you will
pluck downwards, with the finger ending up on the fingerboard and in contact with
the adjacent string. An exception is the rare case in which the upper string is
meant to continue sounding. To avoid damping the upper string, pull sideways so
that the finger clears the other string.
To practice these points, try this example.
