Part 5: Understand the chords you already hold · Lesson 039 / 117
Decode your open C shape
Explain why a five-string grip can still be a triad.
A common open C shape is written x32010 from low E to high E. The x means omit the low E string. The sounded strings give C, E, G, C and E.
There are five sounding strings but only three distinct note names: C, E and G. The grip repeats C and E in other registers. It is still a C-major triad, voiced across more than three strings.
Pick each sounding string and name it. A-string fret 3 is C; D-string fret 2 is E; open G is G; B-string fret 1 is C; open high E is E. This turns a familiar hand position into an understood collection.
Repeated notes help produce the fullness and range of a guitar voicing. Their presence does not add a new chord quality. Later, adding a genuinely new ingredient such as B will turn the triad into a seventh chord.

A concrete example
x32010 sounds C–E–G–C–E. Distinct ingredients: C, E, G. Sounding strings: five.
Try it, slowly
- Hold the shape and name one string at a time.
- Circle repeated note names on paper.
- Play only a few of its strings, then all five, and compare the sound while retaining the same ingredients.
Check one idea
Does five sounding strings mean that this chord contains five different chord tones?
Show the explanation
No. Some pitches repeat by name in another octave. This grip contains only the three distinct chord tones C, E and G.
A good place to stop
You can name the notes of the open C grip and distinguish string count from distinct chord ingredients.
