Every chord, broken down to its notes on adjacent strings. Learn the inversions on one string set, then see the same shape appear everywhere else on the neck — that's how the whole fretboard connects.
This tool uses sound. Make sure your device isn't on silent/mute and your volume is turned up.
The method: a triad has 3 tones (root, 3rd, 5th). Playing it on any 3 adjacent strings gives you 3 inversions — Root Position, 1st Inversion, 2nd Inversion — depending on which tone sits in the bass. Switch to 7th Chords for the 4-note arpeggios. A 4-string bass gives you 2 triad string sets; a 5-string adds a third.
