Playing the guitar often involves revisiting classics that redefined how we think about melody and rhythm. The iconic progression found in songs titled "Used to Know"—most notably the global hit by Gotye—offers a masterclass in minimalism and emotional resonance. Whether you are picking up an acoustic guitar for the first time or looking to refine your fingerstyle technique, understanding the nuances of these specific chords is essential for capturing the haunting atmosphere of the original recordings.

The Anatomy of the Gotye Sound

The primary search for "i used to know chords" almost always leads to Gotye’s masterpiece. The song is built upon a foundation of sparse instrumentation, heavily influenced by a 1967 sample from Luiz Bonfá. On the guitar, this translates into a rhythmic, percussive style that relies more on timing than complex jazz voicings. The track essentially functions in two main sections: the verses, which utilize a two-chord vamp, and the chorus, which expands the harmonic palette to create a sense of release and frustration.

Choosing Your Key: Standard vs. Capo

There are two primary ways to approach the Gotye version. The original key is D minor, which provides a dark, somber tone. However, many players prefer using a capo to simplify the fingerings while maintaining the same pitch.

  1. The Original Key (No Capo): The verse cycles between D minor (Dm) and C Major (C). This requires a quick transition between a minor triad and a major shape. The chorus introduces B-flat Major (Bb), which can be a hurdle for those not yet comfortable with barre chords.
  2. The Capo 5 Version: By placing a capo on the 5th fret, the shapes become much more accessible. You will play A minor (Am) and G Major (G) for the verses. When the chorus hits, you transition to F Major (F). This version is highly recommended for singer-songwriters because it allows for more open strings to ring out, providing a fuller sound for a solo performer.

Step-by-Step Breakdown: Gotye Version

The Verse: The Dm - C Loop

The verse is all about the groove. Instead of strumming full chords, try to mimic the plucking pattern of the original track.

  • Dm Chord: Place your index finger on the 1st fret of the high E string, your middle finger on the 2nd fret of the G string, and your ring finger on the 3rd fret of the B string.
  • C Major Chord: Place your ring finger on the 3rd fret of the A string, middle finger on the 2nd fret of the D string, and index finger on the 1st fret of the B string.

To get the authentic sound, focus on the bass notes. Alternating the root note of the chord with a light percussive slap on the strings will help recreate the wooden, organic feel of the woodblock and xylophone elements in the studio version.

The Chorus: Emotional Escalation

When the chorus begins, the energy shifts. The chords for this section are:

  • Dm - C - Bb - C

The introduction of the Bb (B-flat) is crucial. If a full barre chord at the 1st fret feels too strenuous, a "cheat" version can be used by playing only the middle four strings: 3rd fret on the D, G, and B strings. This keeps the harmony intact without the physical strain. The movement from Bb back to C and then to Dm creates a rising tension that perfectly mirrors the lyrical content of a relationship turning cold.

Lord Huron: A Different Kind of "Used To Know"

While Gotye dominates the airwaves, Lord Huron’s track titled "Used to Know" offers a different harmonic experience. This song leans into the indie-folk aesthetic, requiring a brighter, more driving strumming pattern.

The core progression here utilizes F, Am, and Em. Unlike the Gotye version, Lord Huron’s arrangement feels more linear and progressive. The transition from F to Am creates a melancholic lift, while the Em adds a layer of introspection.

Common Progression for Lord Huron:

  • Intro/Verse: F - Am - F - Am - Em - F - Em - G
  • Chorus: F - Am - Em - F - Am

For this style, using a thin plectrum (0.50mm or 0.60mm) is advisable. It allows for a fluid, shimmering sound that suits the reverb-heavy production typical of Lord Huron’s work. Focus on the upstrokes to emphasize the treble strings, giving the song its characteristic "airy" quality.

Tom Grennan: The Soulful Modern Take

Tom Grennan’s "Someone I Used To Know" moves the "i used to know chords" query into the realm of modern pop-soul. This version is more complex, often played with a capo on the 2nd fret to match his raspy, powerful vocal range.

Chords used with Capo 2:

  • Am7, Gadd11, C, F

The use of Am7 instead of a standard Am adds a sophisticated, jazzy color to the song. The Gadd11 is a specific voicing that keeps the high strings ringing, creating a wall of sound that supports the vocal intensity. If you are playing this version, pay close attention to the dynamics—the verses should be played with palm muting, while the chorus requires full, open strumming to capture the anthemic feel.

Technical Challenges and Solutions

Mastering the Bb (B-Flat Major)

In almost every version of these songs, the Bb chord appears as a significant obstacle. If you are struggling with the barre, consider these three alternatives:

  1. The Power Chord Version: Play only the A, D, and G strings (1st fret, 3rd fret, 3rd fret). This works well on electric guitars with distortion or overdrive.
  2. The Four-Finger Mini-Barre: Use your pinky or ring finger to flatten across the 3rd fret of the D, G, and B strings while your index finger hits the 1st fret of the A string.
  3. The Triad: Play only the 3rd fret of the G string, 3rd fret of the B string, and 1st fret of the high E string. This is the lightest version and is great for folk-style fingerpicking.

Improving Chord Transition Speed

The jump from Dm to Bb or Am to F requires significant muscle memory. A helpful exercise is the "Minute Changes" drill. Set a timer for sixty seconds and switch between the two most difficult chords as many times as possible, ensuring each string rings clearly. Do not worry about rhythm at first; focus entirely on the precision of the finger placement.

Music Theory Insight: Why These Chords Work

Most of these songs are written in the Aeolian mode (Natural Minor) or the Phrygian mode. The relationship between the i (minor tonic) and the VII (major seventh) chord—like Dm to C—is a classic trope in Western music for expressing sorrow or nostalgia.

In Gotye’s case, the constant oscillation between Dm and C creates a feeling of being "stuck" or unable to move on, which is exactly what the lyrics describe. The sudden drop to the VI chord (Bb) in the chorus feels like a collapse, representing the emotional weight of the breakup. Understanding this connection between theory and emotion can help you perform the song with more conviction.

Gear and Tone Recommendations

To achieve the right vibe for these "i used to know chords," your gear setup matters as much as your finger placement.

  • Acoustic Players: Use phosphor bronze strings for a warmer, more balanced tone. Since these songs are emotionally driven, a mid-sized body guitar like an Auditorium or OM shape is often better than a large Dreadnought, as it provides better note definition for the intricate verse parts.
  • Electric Players: Keep the gain low. A clean tone with a hint of "edge of breakup" is ideal. Use the neck pickup for the verses to get that tubular, woody sound, and switch to the middle position (both pickups) for the chorus to add clarity and punch.
  • Effects: A subtle plate reverb and a short slapback delay can emulate the studio production of the 2010s. For the Lord Huron style, increase the decay on your reverb to create a "wash" effect.

Practical Practice Schedule

If you want to master these chords within a week, follow this structured approach:

  • Day 1-2: Focus exclusively on the Verse loop. Whether it's Dm-C or Am-G, get the rhythm perfectly steady. Use a metronome set to 64 BPM.
  • Day 3: Introduce the Chorus chords. Specifically, practice the transition into the Bb or F chord.
  • Day 4: Combine the sections. Practice the "switch"—the moment the verse ends and the chorus begins. This is where most players stumble.
  • Day 5: Work on dynamics. Practice playing the verse very quietly and the chorus with much more force.
  • Day 6-7: Play along with the original recordings. This will help you internalize the tempo changes and the subtle percussive hits that make these songs unique.

Final Thoughts for the Modern Guitarist

The beauty of learning "i used to know chords" lies in their versatility. These progressions are not just limited to the songs they originated from; they are foundational blocks used across thousands of tracks in the pop, rock, and folk genres. By mastering the Dm-C-Bb relationship or the Am-G-F variations, you are adding essential tools to your musical vocabulary.

As you progress, try to experiment with the voicings. Maybe add a 9th to the C chord (Cadd9) or play the Dm as a Dm7. Music is a living thing, and while these guides provide the map, your personal touch is what will make the performance truly yours. Whether you’re playing for a small group of friends or just for your own enjoyment, these chords offer a deep well of emotional expression that never seems to go out of style.
