Example 2   The next two notes are on the 2nd string. Alternate between the open 2nd string and the 2nd string at the 3rd fret.

1 -- Pick the open 2nd string. ('Open' means no fingers on the frets.) Let this note ring for a moment.

2 -- Place your finger on the 2nd string at the 3rd fret.

3 -- Pick the 2nd string. Let the note ring for a moment.

4 -- Remove your finger from the string.
