Augmented Triad Inversions 3-String Shapes With Fingerings

The charts show augmented triad inversions in close-position across all adjacent 3-string groups on the guitar. The chord shapes are labeled using finger numbers, with a hybrid variation that also includes scale degrees.

An augmented triad consists of three tones: the root, major 3rd, and augmented 5th. In close position, these chord tones are arranged as closely together as possible, without spreading notes across octaves (which would then be referred to as an open voicing or spread voicing). Each inversion contains the same three notes in a different order, which changes the bass note while preserving the chord quality. The inversion with the 3rd in the bass is called the 1st inversion, while the inversion with the 5th in the bass is called the 2nd inversion.

These close-position triads provide one of the most fundamental and practical systems for understanding harmony on the guitar. Because each shape contains only the three essential chord tones, the relationships between inversions, intervals, and fretboard positions become easier to see, hear, memorize, and apply in real playing situations. The compact 3-string shape also makes these voicings efficient and useful for voice leading, chord melody, and improvisation.

How You Can Use This Chart

• Learn all inversions of an augmented triad on any adjacent 3-string group (1-3, 2-4, 3-5, 4-6).
• Understand how each inversion of a basic augmented triad is built exclusively from its three essential tones (root, 3rd, 5th) without any extra or duplicated notes.
• See how each inversion is positioned on the fretboard in relation to the other inversions.
• Learn multiple playable locations for the same triad across the neck.
• Use close-position chord shapes as compact, efficient, easy-to-play and control voicings.
• Build a foundation for wider voicings such as drop voicings and extensions by first becoming comfortable with the simplest close-position system and focusing on the most fundamental chord structure.
• Train your ear to recognize chord quality and inversions by sound, as close-position voicings make interval relationships more apparent.
• Use the 3-string limitation as a powerful learning tool to develop harmonic understanding and interval-based thinking instead of relying on fixed shapes, chord names, or full 6-string chords.
• Use close-position triads as a reliable fallback when you are unsure how to play more complex chord voicings.

Chart Features With Practical Learning Benefits

• All String Sets: Covers all playable close-position triads on string groups 1-3, 2-4, 3-5, and 4-6, giving you full fretboard coverage.
• Two Learning Layouts: Charts come in two visualizations: one maps the inversions across a continuous fretboard layout, which allows you to understand them in context, visually track how chord shapes move, and play the same chord with different bass notes, while the other displays each inversion as an individual diagram for a more focused view. Just choose whichever layout works best for you.
• Matches Your Viewing Angle: Chord diagrams are often shown vertically with the nut at the top, which doesn't match how the fretboard actually looks when you're holding the guitar. Charts with separated shapes feature horizontal diagrams with the nut on the side, matching your real point of view on the fretboard.
• Movable: You can take any shape and move it anywhere on the fretboard to get the chord with the exact bass note you want.
• Know How to Play the Shape: Diagrams have beginner-friendly finger numbers that show you which fingers to use instead of generic intervals and other types of presentation you might not yet be comfortable with.
• Execution + Theory: A chart with a hybrid layout gives you the best of both worlds by combining beginner-friendly finger numbers with scale degrees. The primary focus is on finger numbers, so you immediately know how to play the shape, while scale degrees are added alongside to show the harmonic function of each note. This dual-presentation approach lets you shift your focus between theoretical understanding and physical execution without ever needing to look up a different chart.
• Self-Contained: Each chart stands on its own, with clear headers and footers that give you full context. Even when you print it, you always know exactly what you're looking at.
• Fretboard Navigation: In the continuous layout, fret numbers are shown above the diagram, helping you locate your position on the fretboard and move around it more easily.
• Color-Coding: Shapes have different colors to help you focus on one shape at a time.
