The Key of G
So far, everything in this book has been in the key of C. After C, one of the next most common keys is the key of G. Here is the G major scale spanning two octaves in the treble staff. If you have trouble reading the high notes, take the scale slowly and name each note as you play it. These new notes are important, as they will be used in Blues riffs and runs in the following lessons. Be careful with the crossover at the change of octaves.
Here are some more new notes, this time in the bass staff. Notice the half notes in the last two bars. These notes G, C and D are particularly important because they are the root notes for chords I, IV and V related to the G major scale.
The D Chord
The D chord contains the notes D, F# and A. It is an important new chord for playing in the key of G. The diagram shown here illustrates the D chord in root position.
In the key of G, chord I is G, chord IV is C and chord V is D. These three chords are shown here in root position for each hand.
The next three examples contain common combinations of inversions of the chords G, C and D. They will enable you to change smoothly between these chords with the right hand.
