These three diagrams illustrate the root position (1 3 5), first inversion (3 5 1), and second inversion (5 1 3) of the F chord.
The next example uses the root position, first inversion, second inversion, and an octave of the root position of the F chord.
Here are some of the ways inversions can be used in Blues. The following example contains all three positions of a C major chord played over a shuffle rhythm.
One of the reasons inversions are so useful is that they enable you to find chord shapes which are close together on the keyboard. Here the C chord appears in root position, the F chord is in second inversion and the G chord is in first inversion. The left hand plays the root note of each chord.
This example applies these inversions to the 12 Bar Blues progression. Notice how effective the use of a simple repeated rhythm can be.
