Inversions (also called "Slash Chords"), change the order of the notes of a chord by playing a different note as the lowest note of the chord. The chord symbols are written using a slash (/) such as C/E which means to play a C Major chord with the E note as the lowest note in the chord. These chord symbols are common to other instruments such as keyboards.
All of these patterns are moveable allowing you to reuse them as you move up and down the guitar neck.
You will need to know the names of the notes on the Fretboard for the 6th, 5th & 4th strings and how to spell chord notes to use inversions efficiently.
For your convenience we have included the lessons on Chord
Voicings since it is common to use a mix of Chord Voicings and Inversions
Voicings are used to play chords without using all of the notes of a chord. They also provide a means to play 7 note chords such as 13ths when you only have 6 strings or to provide a more open sound for other chords such as 9ths and 11ths.
