Em and Arpeggios

string 1 is the thinnest string (nearest the ground), and 6 is thickest. x means: don't play the string. O means: open, no fret. Here is the E minor chord, and an E minor scale:

1-----o-----------------------------
------o-----------------------------
------0-----------------------------
------2------------------------o--2-
------2--------------o--2--3--------
6-----o-----o--2--3-----------------
   Em Minor   Em scale   
   chord

An apreggio means going up and down the notes in a chord. There are meany ways. Here is an example:

1--------------o---------
------------o-----o------
---------o-----------o---
------2------------------

6------------------------
   Em arpeggio        then repeat

(It is useful to keep 5th string fretted even though not played)
