The question of How Many Guitar Chords Are There might seem simple on the surface, but it quickly unravels into a fascinating exploration of music theory and the very nature of chords on the guitar. There isn’t a single, straightforward answer, as it depends heavily on how you define a “guitar chord” in the first place.
Are we talking about just the common, everyday chords that guitarists frequently use? Or are we delving into every conceivable combination of notes possible on the fretboard, even those that might sound incredibly dissonant or be physically challenging to play? And crucially, where do we draw the line on what constitutes a chord – is it two notes, or does it require the traditional minimum of three?
For the purpose of this exploration, we’ll adopt the widely accepted music theory definition: a chord consists of at least three notes, forming what is often referred to as a triad. Let’s break down the numbers and explore the vast world of guitar chords.
Common Guitar Chords: A Practical Count
If we consider the most frequently used guitar chords – the ones that form the backbone of countless songs – the answer becomes more manageable. Think of open chords, barre chords, and power chords rooted on the lower strings.
Given that there are 12 unique root notes within each octave on a guitar string before the notes repeat, there are theoretically 12 possible variations for every basic chord shape. Let’s calculate the common chords:
- 6th String Root Barre Chords: Considering major, minor, and power chord (neutral) versions, and common barre chord shapes utilizing three, four, five, or six strings, we arrive at: 144 (12 root notes x 3 chord types x shapes).
- 5th String Root Barre Chords: Similar to the 6th string barre chords, we have: 144 (12 root notes x 3 chord types x shapes).
- 4th String Root Triads: Focusing on triads rooted on the 4th string, again in major, minor, and power chord forms: 36 (12 root notes x 3 chord types).
- Common Open Chords: Including typical major and minor open chord shapes: 14 (Approximately 7 common shapes x 2 variations).
Total Common Guitar Chords: 338
This number, while substantial, is still a limited view. It doesn’t account for a wealth of chord variations that guitarists use to add color and complexity to their playing.
The Universe of All Possible Guitar Chords: A Technical Perspective
To truly grasp the sheer number of guitar chords, we need to expand our scope to include everything theoretically possible. This means considering a wider range of chord types, including diminished chords, augmented chords, slash chords, extended chords, and many more.
To estimate this larger number, we start by considering the chromatic scale, which includes all 12 notes plus sharps and flats. While the original article mentions 17 root notes which seems unusual in standard musical context (there are typically 12 unique pitch classes in Western music theory), for the sake of replicating the calculation method and highlighting the concept of vast possibilities, we can use a similar approach focusing on chord variations and voicings.
Instead of 17 root notes, let’s consider 12 chromatic root notes (A, A#, B, C, C#, D, D#, E, F, F#, G, G#). Then, let’s acknowledge that there are numerous chord variations beyond just major, minor and power chords – including 7ths, maj7ths, diminished, augmented, sus chords, and altered chords. For simplification and to align with the original article’s implied methodology, if we consider a simplified number of chord variations and voicings across the fretboard, we can arrive at a large number.
The original article uses a multiplication of 17 x 26 x 5 = 2210. While the exact derivation of “26 variations” and “5 versions” is not clearly defined, it aims to illustrate that by considering different chord types and different ways to play them across the guitar neck, the number of possible chords explodes.
To provide a more conceptually sound, albeit still simplified, estimate:
- 12 Root Notes: Chromatic scale.
- Numerous Chord Types: Major, minor, dominant 7th, major 7th, minor 7th, diminished, augmented, sus4, sus2, etc. – easily exceeding 26 variations if we include extensions and alterations.
- Multiple Voicings/Positions: For each chord type and root, there are multiple ways to play it across the fretboard. While “5 versions” is arbitrary, it’s true that many chords can be played in several different positions.
Using the original article’s calculation logic as a template, even if the exact numbers are debatable, the key takeaway remains: the number of possible guitar chords is vast, reaching into the thousands. The figure of 2210 total guitar chords serves as a symbolic representation of this expansive potential.
Beyond the Count: Exploring the Fretboard
It’s important to note that even this larger number doesn’t encompass every single theoretical combination. We haven’t considered dyads (two-note combinations, which some might consider incomplete chords) or every single micro-variation possible by altering fingerings and note combinations, especially in higher fret regions.
However, for practical and academic purposes, the idea that there are thousands of guitar chords is a powerful one. It underscores the immense versatility of the guitar and the endless possibilities for musical expression. Instead of being overwhelmed by the sheer quantity, guitarists can see this vastness as an invitation to explore, experiment, and continually expand their sonic palette.
