It's the same as B Major when the guitar is open, go two frets up in scale on the 5th (A) string (with the capo this puts you on the 5th fret) and form a barre with your pinky or ring finger on the 7th fret across the fourth through 2nd strings (you can barre the 1st string too as long as you don't play it, 6th string isn't played either.) There are other configurations but this seems like the best configuration in the area of the capo area itself. Alternatively you could barre a traditional D Major chord shape at the tenth fret but that might sound too chimy for you.
If you use the G fingering with the capo on the third fret, you are playing a Bb chord, which is three half-tones higher than G. If you wish to play in the key of G with the capo on the third fret, use the typical fingering for E, which is three half-tones lower than G.
By putting the capo on the second fret and playing a C chord, will create the chord D sound. By playing Am you will get Bm, and by playing Dm you will get Em.
Raising the pitch of the whole guitar a major third, such as E -G#.
Te capo does not change the location of the chords, it only places the open strings at where you place the capo, in your position, the open strings are at the 7th fret. The capo is only ever useful if you have difficulty playing full chords and you only need to change a few during a performance or if you require the open strings at a more convenient position for doing leads for songs played in a certain chord, where the open strings are used often.
Standard tuning for a guitar is key of "E".
Put the capo on the second fret and use the "C" chord configuration - this is equivalent to a "D" with no capo.
If you use the G fingering with the capo on the third fret, you are playing a Bb chord, which is three half-tones higher than G. If you wish to play in the key of G with the capo on the third fret, use the typical fingering for E, which is three half-tones lower than G.
D chord
To play a G chord with a capo on the 5th fret, place your fingers in the shape of a D chord without the capo. The capo essentially moves the chord shape up five frets, so the D shape becomes a G chord when played with the capo on the 5th fret.
To play a G chord with a capo on fret 4, place your fingers in the shape of a D chord without the capo. The capo on fret 4 will raise the pitch of the chords, allowing you to play a G chord.
When using a capo on the 3rd fret, the chord shapes for a song will be three half steps higher than the original chords. For example, a G chord shape without a capo would become a B chord shape with the capo on the 3rd fret.
When using a capo on the 4th fret, the chord positions for playing a song will be four semitones higher than the original positions. For example, a G chord will sound like a B chord with the capo on the 4th fret.
When using a capo on the 4th fret, the chords played are transposed up four half steps. For example, a G chord without a capo becomes a B chord with a capo on the 4th fret.
The chord progression for the song when played in capo 2 key is D - A - Bm - G.
An A. That would move the guitar 2 half steps or one whole step and yes making that an A
To play a G major chord with a capo on the 2nd fret, place your fingers on the second fret of the A string, third fret of the low E string, and third fret of the high E string. Strum all the strings except for the low E string.
By putting the capo on the second fret and playing a C chord, will create the chord D sound. By playing Am you will get Bm, and by playing Dm you will get Em.
