The minor chords have what most people say is a sad sound, and they are used in many sad songs.
The first chord is the Em chord
. It is very easy to play, and only requires two fingers, on the fourth and fifth string and second frets.
Next is the Am chord
, also easy with three fingers required. They are on the second, third, and fourth string. The second string is on the first fret, and the third and fourth stings are on the second fret.
The last chord is the F chord
, which is easy too. Unlike on the Am chord, the F chord uses four fingers: one on the first string first fret, one on the second string first fret, one on the third string second fret, and one on the fourth string, third fret. There is a variation that you could play the first and second string on the same finger, but play both and see which one you like better.
