You need as many chords as your song requires, ranging from just one or two for minimalist styles (like some dance or blues) to three or four (very common in pop/rock) up to eight or more for complex ballads, with the key being repetition and harmonic rhythm, not the quantity, as simple progressions like I-V-vi-IV are incredibly popular.
The 80/20 rule (Pareto Principle) in songwriting means 80% of a song's impact, memorability, or success comes from just 20% of its elements, like the core hook, chorus, or lyrical phrase, with the rest being polish. It encourages songwriters to identify and focus on these high-impact areas (e.g., catchy melodies, strong core lyrics) to maximize results, while also applying the principle to their process by focusing on the 20% of activities that yield 80% of their progress, such as identifying the few core skills or marketing efforts that truly work.
7th chord rules involve adding a note a seventh interval above the root of a triad, stacking thirds (root, 3rd, 5th, 7th) to build them, and understanding that the quality of the 7th (major, minor, diminished) changes the chord's sound and function, with the dominant 7th (major triad + minor 7th, like C7 or C-E-G-B♭) being crucial for resolution in progressions. Key rules focus on construction (stacked thirds), notation (e.g., maj7, m7, 7), and tendency tones (like the tritone in dominant 7ths that resolves).
The 80/20 rule (Pareto principle) applied to guitar means 80% of your musical results come from focusing on just 20% of crucial skills, like core chords, rhythm, scales (pentatonic/blues), and timing, cutting out "fluff" for faster progress. It suggests focusing heavily on essential skills like basic chords, strumming, and rhythm (the "80%") to achieve most of your playing goals, rather than getting lost in advanced theory or complex solos, which often yield less practical benefit early on.
No, you don't need a high IQ to play guitar; musical talent involves different intelligences, like musical intelligence, and proficiency comes more from discipline, pattern recognition, and consistent practice than raw IQ, though learning music can even boost cognitive skills. While some studies suggest musicians might have higher IQs or brain connectivity, many average or below-average individuals become excellent players through dedication to rhythm, melody, and harmony.
Widely regarded as the greatest and most influential guitarist in rock history, Jimi Hendrix was born on November 27, 1942 in Seattle, Washington, to African-American parents Lucille (Jeter) and James Allen Hendrix.
The "forbidden chord" in music refers to the tritone, an interval spanning three whole tones (six semitones), known for its harsh dissonance, historically called diabolus in musica (devil in music) and avoided in medieval church music for sounding unpleasant and unsettling, but now a crucial tool in genres from jazz to metal for creating tension.
Jimi Hendrix's "favorite chord" is widely considered the dominant 7th sharp 9th (7#9), famously known as the "Hendrix Chord," characterized by its tense, bluesy sound, often played as an E7#9 in songs like "Purple Haze" and "Foxy Lady," blending major and minor qualities with a sharp ninth. He used variations of this chord and thumb-over-the-neck techniques to add richness and movement, creating his signature sound.
The dominant chord (V) was introduced at grade 5. Chord V7 is also known as the “dominant 7th” chord. It is built from the dominant triad, plus another third added on top: the 5th, 7th, 2nd and 4th notes of the scale. In C major, the dominant 7th chord contains the notes G, B, D and F.
They have the same intelligence quotient as other people, but their brains are more efficient at processing information and solving problems. It's not because you're a musician that makes you smarter—it's because of your personality type that makes you a musician.
Apparently, Taylor Swift really likes voice notes; she uses this method to compose most of her songs. (Sometimes she records them on the run; think Senstone.) According to Ryan Tedder, Swift's dedication to the note-taking habit is unparalleled.
The "4 golden chords" refer to the ubiquitous I–V–vi–IV progression, a simple yet powerful chord sequence (like C-G-Am-F in C Major) that forms the backbone of thousands of pop, rock, and country songs, allowing beginners to play countless hits by just changing the key. It's considered a musical shortcut, unlocking easy access to a massive catalog of music by repeating this fundamental pattern.
Popular 3-chord songs span genres and eras, often using common progressions like G-C-D or A-D-E, and include classics like The Troggs' "Wild Thing," CCR's "Bad Moon Rising," Bob Dylan's "Blowin' in the Wind," Johnny Cash's "Folsom Prison Blues," and modern hits like Ed Sheeran's "Thinking Out Loud" or The Weeknd's "Blinding Lights," proving simple structures create enduring hits.
The Rule of Three in songwriting is a compositional guideline suggesting that presenting a musical idea once makes it intriguing, twice establishes a pattern, but repeating it a third time risks listener fatigue, so it's best to introduce variation or a new idea after the second repetition to keep listeners engaged, often summarized as "state, repeat, vary". It's a principle rooted in human psychology, making music more memorable and satisfying by balancing repetition with novelty, applying to melodies, rhythms, and even the number of elements in a musical passage.
1: Jimi Hendrix
Not only did Jimi Hendrix expand the sonic possibilities of what a guitar could do, but he also found uncharted places that a guitar could take you to.
As I mentioned at the start, the proper musical name of the Hendrix Chord is the 7#9 chord. Jimi Hendrix popularised its sound, but he was not the first person to use it, and he certainly didn't invent it.
73 for all his early stuff. Matt Bellamy, Alex Turner and Josh Homme all love a bit of yellow Dunlop action, and in all honesty, it's not hard to see why. Though these are easily a quarter of the thickness of anything I'd normally use, the sound is bright, well balanced, and strums brilliantly.

The musical interval of a tritone or diminished fifth was referred to as The Devil's Chord (or the Devil In Music) and subsequently banned by the Roman Catholic Church.

Jimi Hendrix
When you consider the amount of unique guitar solos and memorable tunes Hendrix gave to the world, it's easy to assume he would have been fluent in reading music. But in an interview in 1969, he was asked whether he is able to read music and the legend replied, “No, not at all”.
