and related Strings Sets

This article aims to go a little bit in depth with the Open Triads (or Drop 2 triads) and it will treat the concept from both a theoretical point of view and a practical way to arrange them on the guitar fretboard.
What Open Triads are?
Referring to a major triad in close position, 1 3 5, we can obtain a Drop 2 voicing from it by modifying its note order. This can be accomplished by lowering an octave the 2nd voice of the triad in close position, so that, from 1 3 5 we obtain 3 1 5.
This 3 1 5 voicing is a Drop 2 major triad in first inversion.
By doing the same with the inversions of the close position voicings, the first inversion 3 5 1 become 5 3 1, and the second inversion 5 1 3 become 1 5 3.
By summarizing we have the following possible six voicings for a major triad:
Close position voicings: 1 3 5, 3 5 1, 5 1 3.
Drop 2 voicings: 1 5 3, 3 1 5, 5 3 1.
Arranging Open Triads on the guitar fretboard
On the guitar these voicings can be arranged on three different ways that correspond to different strings set.
1) placing the bottom voice on a string, separated by the other two voices that belongs to two adjacent strings.
This implies that we can use the following string sets: [6 4 3], [5 3 2], [4 2 1].
2) placing the top voice on a string, separated by the other two voices that belongs to two adjacent strings.
This implies that we can use the following string sets: [6 5 3] , [5 4 2], [4 3 1].
3) placing the voices in non adjacent strings. This implies that we can use the following string sets: [6 4 2], [5 3 1].
The following video show how to obtain drop 2 triads voicings with guitarLayers and how to visualize them on the above mentioned strings sets.
This video shows how guitarLayers can generate quickly and automatically the Drop2 Open triads voicings
GuitarLayers can generate automatically drop voicings and inversions for common and custom three-notes and four-notes chords. Learn more about all its other professional features.
GuitarLayers is a professional macOS guitar learning and teaching software. It allows you to visualize and manage, scales, chords and arpeggios shapes through a fully parametric control interface.
Moreover it enables you to visualize harmonic concepts by overlapping shapes on the guitar fretboard thanks to a powerful layering system.
