Inversions of chords and arpeggios
The idea of inversions is that you take the notes of the chord or arpeggio which essentially is the same but executed differently, so as an example if you have a C chord, that consists of a root note, a third which gives you the information of whether its minor or major and in this case its Major. so the notes would be root note is C, the Major third is E and the fifth is G. So those three notes can be used again in a different sequence, lets use the terms 1, 3 and 5, then that sequence can be changed to 3, 5 and 1 and also 5, 1 and 3 giving you the same three notes but in a different sequence, for the chords they actually get the same name but with either the third or fifth in the bass. For the Arpeggios we don't give them names


The reason this info is useful not only to give you away to shred away in the arpeggios is that we can make a iced harmony of the notes which also makes it easier to play so we don't have to move up and down so much on the fret board, so if you're one area playing a C arpeggio and the next arpeggio you go into which could be a G arpeggio you do a quick analasys if theres any re use of note, and if you watch the full video you'll see that the note G is both in the C and G arpeggio, so this also gives you a hint of where you in the same area you can break into the next arpggio. If you don't want to do the theoretical analasis then you can also easily just but finding the three inversions on the fret board find the arpeggios that would fit the closest, to get a fuller understanding please watch the complete video


Harmonizing the Aroeggios - non theoretical
To give you a non theoretical version of the usage of harmonising the arpeggios let me give you the explanation of the C major arpeggio and the G major arpeggio, and lets take an example of starting on the high E string with the third of the C major arpeggio which will then be the 12th fret pulling of to the 8th fret, if these triad arpeggios are new to you then see the below picture. Then at some point when we want to break into the G major arpeggio we start on the G major inversion with the fifth which is the note D which is on the 10th fret pulling off to the third which is B making these two arpeggios harmony much smoother than moving way down on the fret board to play the same inversion as we did in C in the G thus easier mechanically


Circles are the C Major and the triangles are the G Major, the black squares are the note G which the two arpeggios share, try out the difference between moving the first inversion versus using the inversions
