The G Major Chord
G major builds directly from the G7 shape you already know. Start by forming G7, then make one change: add your 4th (little) finger on the 1st string just behind the 3rd fret, and lift your 1st finger. The 2nd and 3rd fingers stay exactly where they were for G7.
Practise moving between G7 and G major several times until the small adjustment feels natural. G major has a fuller, warmer sound than G7 because all the strings ring freely without the tension that G7 creates.
Some beginners play G major without the 4th finger to make it easier. Do not do this. The 4th finger is essential for barre chords, advanced chord shapes, and lead guitar. Train it from day one — a few minutes daily builds strength quickly.
The B7 Chord
B7 is the most complex chord so far — it uses all four fingers. Place them like this:
- Finger 1 on the 4th string, behind the 1st fret
- Finger 2 on the 5th string, behind the 2nd fret
- Finger 3 on the 3rd string, behind the 2nd fret
- Finger 4 on the 1st string, behind the 2nd fret
Do not play the 6th string with B7. Strum from the 5th string downward. B7 has a bright, slightly tense character that naturally wants to resolve to E minor — just as G7 leads to C. You will find B7 and Em paired together in many songs.
B7 may feel awkward at first because all four fingers are used simultaneously. Practise placing and lifting it several times at the start of every session. Within a few weeks it will feel natural.
E Minor (Em)
E minor is the simplest and most resonant chord you have learned. Just two fingers:
- Finger 1 on the 5th string, behind the 2nd fret
- Finger 2 on the 4th string, behind the 2nd fret
Strum all 6 strings freely. All six strings ring as part of the Em chord, giving it a rich, deep, full sound. Em is used constantly in rock, folk, classical, and virtually every style of guitar music.
D Major
D major uses only the top four strings:
- Finger 1 on the 3rd string, behind the 2nd fret
- Finger 2 on the 1st string, behind the 2nd fret
- Finger 3 on the 2nd string, behind the 3rd fret
Begin your strum on the 4th string — do not play the 5th or 6th strings. D major has a bright, high-register, joyful sound. It is one of the most commonly used chords in folk and pop music.
D major and D minor are completely different chords with very different sounds. D major (bright, happy) and D minor (dark, melancholy) appear similar in chord diagram form but use different fingerings. Always check the chord symbol carefully.
Chord Sequences to Practise
G / Em / Am / D / G / C / D / G (four beats each). This sequence in the key of G underpins hundreds of folk and pop songs.
Em / D / C / B7 / Em / Am / B7 / Em (two beats each). This moody sequence in E minor is classic for ballads and Spanish-influenced music.
