There are thousands of Guitar Chords that can be played on a normal six string guitar. All Chords stem from their root Chords “A” through “G”. The reason there are so many Chords is, there are different ways of playing the same Chord that sounds slightly different, but is the same chord. For every regular Chord, there is also a Bar chord that is equal to it. For example, you can play an “A” chord using the regular fingering position, and then also by playing a Bar Chord on the fifth fret. Additionally, the twelfth fret (double dotted) is exactly one full octave (same note name but twice as high) above the open notes of the strings. This means that if you can play an “A” bar chord on the 5th fret, you can also play an “A” bar chord on the 17th fret (12+5)…This means that potentially, every single chord can be played a minimum of 3 times along the fret board and sound the same.
Many professional guitar players use other variations of the regular chords deliberately when they write music. It is part of an artistic variable that is at your disposal when composing music.
Sometimes, the way certain songs progress and the chords that are played cause the need for playing alternative types of chord for simplicity’s sake. You don’t want to have to be playing up near the ninth fret, then in an instant jump down to the 1st or 2nd fret to play a certain chord, then jump back up again. There’s always another way that the same thing can be played.
Another reason why Chord variations may be a good idea is, some chords are a bit rougher on the hands and many new guitar players have not yet developed the strength to make the shape for proper Bar chord position. So using alternative fingering positions can help you to still be able to play some chords while you are adjusting to the newness of guitar playing.
As you play the guitar more and more, your hands will naturally get stronger, and more flexible, allowing you to eventually master the tough chords. Just give yourself lots of time for your hands to get used to stretching in ways they never have before.
Soon, you will be able to see chord variations on the “Chords” page along with the regular ones.
