Watch the A Minor Chord Inversions online guitar lesson by Frank Vignola from Inversion Excursion
Now we will move on to open or spread inversions of triads. A spread inversion is simply displacing one of the notes in the triad to a different octave skipping a string. Instead of the inversions on strings 1-2-3 we will play the inversions skipping a string using 1-2-4 strings and/or 1-3-4 strings. So the middle string note of the closed inversion will be played an octave higher on the first string to create a spread inversion. We determine the inversion by what note or interval is in the bass note. Root note is Root inversion, the 3rd in the bass is 1st inversion and the 5th in the bass is 2nd inversion. For each inversion, look at the chord and pick out each of the chord tones naming the notes.
