Chord inversions are a great way to use the same series of notes in a chord to get different voicings. For the example in this video use a C-major triad, which contain the notes C, E, G. Playing these three notes in this pattern is called the root inversion. The first inversion is to use the root being C and put the note up one octave. Now the chord is played E, G, and C. The second inversion is two take the E and put that note up one octave. Now the pattern goes G, C, and E. These three inversions will work for any triad being played on the keyboard. It is also important to remember that the root inversion has two positions low and high. A good exercise to practice these inversions is to start on the root inversion, play the first, second, and the octave root inversions in a row. Once you are able to easily finger the chords going up, then finger them back down. Eventually you should be able to go up and down the pattern with ease at a certain tempo. Remember to work all keys.
