There are many different kinds of chords in music and all are important since they are used so frequently. Open chords mean that none of the notes are sharps or flats. They are usually played as the 1st, 3rd and 5th notes of a scale. There are also many different kinds of 7th Chords; G7, D7 and C7 are just three of them.

To play the G7 chord: -
· Find the third fret of the sixth string with your third finger.
· Next you find the 2nd fret of the fifth string with your 2nd finger.
· And then the first fret of first string with first finger.
· The other strings are played in open position

If your fingers are nicely curled, you won't find it too hard to keep them on these notes. Strum the chord. G 7 chord has only one note different to G major chord.

The C7 chord has only one note different to the C major chord. To play C7 you need to first form the C major chord thus: -
· Third finger, third fret, fifth string.
· Second finger, second fret, fourth string.
· First finger, first fret, second string.

Then you add: -
· Fourth finger, third fret, third string. Strum the five bottom strings.

To play a D7 Chord (similar to D major): -
· Second finger, second fret, third string.
· First finger, firs fret, second string.
· Third finger, second fret, first string.
· Strum bottom four strings.

In the chord charts for these chords, those strings that are not played (strummed) will be shown with an x above them. You should play each note separately first to check for accurate sound. Practice playing these chords, moving from chord to chord. As you do so, say the name of each chord so you'll get used to its pattern and name.

9th Chords are exactly like 7th chords but with a 9th added to it, that is, a 9th is an octave higher than the tonic (starting note), then you add a second (2frets).

The ninth chord formula is: 1-3-5-b7-9.
The major 7th minor 9th chord formula is: 1-3-5-7-9
The minor 7th minor 9th chord formula is: 1-b3-5-b7-9

The major 9th chords are: -

· A = A-C#-E-G#-B
· B = B-D#-F#-A#-C#
· C = C-E-G-B-D
· D = D-F#-A-C#-E
· E = E-G#-B-D#-F#
· F = F-A-C-E-G
· G = G-B-D-F#-A
