Pitch-Perfect: The World Cup’s Most In-Tune Fandoms, Ranked Across All 48 Nations

With the 2026 World Cup underway, the anthem ceremony before each match has become a moment of national pride – and fierce debate. But which nation's supporters and players actually sing their anthem most in tune? To find out, the anthem singing of all 48 competing nations was analyzed by The Action Network, using vocal isolation and pitch detection software, measuring each nation's performance across four components: pitch accuracy, commitment, melodic richness, and pitch stability.

Subsequently, each nation received a composite score from 0 to 1, where 1 was the highest possible score. The score was weighted primarily toward two factors: how accurately supporters and players hit the correct notes (pitch accuracy, 40% weight), and how much of the anthem was actively sung rather than mumbled or left silent (commitment, 40% weight). Melodic richness – whether the singing had genuine melodic variety rather than a monotone drone – and pitch stability – how steadily notes were held – each contributed 10% weight. Nations were then grouped into four statistical tiers, from Tier 1 (the most in-tune) to Tier 4 (the lowest-scoring), providing an additional layer of context on top of the individual rankings.

The analysis revealed stark differences across the field. Japan emerged as the most in-tune nation at the 2026 World Cup, leading a top tier of 12 nations whose scores are statistically distinct from the rest – and the only nations in the analysis to score above the in-tune threshold as a group. At the other end, Ecuador, Panama, and Argentina ranked as the three lowest-scoring nations in the dataset.

Highlights

• Japan ranked 1st as the most in-tune fandom across all 48 nations with a 0.784 score; Curacao ranked 2nd with a 0.670 score, and Iran 3rd with a 0.660 score.
• The three lowest-scoring fandoms were Ecuador (48th, 0.130 score), Panama (47th, 0.210 score), and Argentina (46th, 0.212 score).
• Iran (3rd overall) recorded the highest pitch accuracy of any nation in the entire dataset at 92.9% – meaning their supporters and players hit the correct notes more precisely than any other fandom. 
• Colombia (44th overall) recorded the lowest pitch accuracy score of any nation at 52.7% – meaning their supporters and players were the least precise at hitting the correct notes across all 48 nations. 
• The United States (9th overall) and South Africa (10th overall) posted the highest commitment rates of all 48 nations at 87% each, meaning their supporters and players sang a greater proportion of their anthem than any other nation.
• Tunisia (42nd overall) recorded the lowest commitment rate of all 48 nations at just 19%, meaning their supporters and players sang less than a fifth of the anthem.
• Every nation in the analysis scored the maximum on melodic richness, confirming that all 48 fandoms produced genuine melodic movement rather than a monotone drone.
• Japan (1st overall), Curacao (2nd overall), Haiti (4th overall), Cape Verde (5th overall), Algeria (8th overall), Qatar (14th overall), and Portugal (27th overall) each recorded the highest pitch stability score in the dataset at 1.00 –meaning their supporters and players held their notes without wavering throughout the anthem.
• Argentina (46th overall) recorded the lowest pitch stability score of any nation at 0.73, with Spain (45th overall) close behind at 0.76 – their supporters and players struggled more than any other nation to hold their notes steadily throughout the anthem. 

How To Read The Interactive Graphic

The interactive graphic below ranks all 48 nations by their composite score, displayed as horizontal bars. The longer the bar, the higher the score. The vertical line on each bar determines which tier a nation is placed in. Nations are then color-coded by tier: teal for Tier 1, purple for Tier 2, amber for Tier 3, and red for Tier 4. Hovering over any row reveals the full breakdown of all four component scores for that nation. You can also switch to one of the languages of all the participating nations. 

The Most In-Tune Fandoms (Tier 1)

Japan topped the ranking as the most in-tune nation with a composite 0.784 score, the highest in the analysis. The Japanese supporters and players combined the strongest pitch accuracy in Tier 1 at 79.2% with the highest commitment rate in Tier 1 at 82% – meaning they were both the most precise and the most active singers among the top-ranked nations. Japan also recorded maximum pitch stability, and led the ranking in every variant of the analysis, making it the most consistent result in the dataset.

Curacao ranked second with a 0.670 score, combining solid pitch accuracy (83.1%) with a commitment rate of 56% – comfortably above the Tier 1 average. Curaçao also achieved maximum pitch stability. 

Iran placed third overall but recorded the single highest pitch accuracy score of any nation in the entire dataset at 92.9% – meaning their supporters and players hit the correct notes more precisely than any other fandom at the tournament. Where Japan balanced accuracy and commitment, Iran's result was almost entirely accuracy-driven – their commitment rate of 39% was one of the lower figures in Tier 1, suggesting a smaller portion of supporters and players actively singing, but those who did were exceptionally precise.

The United States and South Africa (9th and 10th, respectively) were the commitment story of the tournament. Both posted commitment rates of 87% – the joint highest of all 48 nations – meaning their supporters and players sang a greater proportion of their anthem than any other nation. Their overall scores were held back by relatively lower pitch accuracy figures (61.1% and 60.7% respectively), but their volume of active singing pushed them firmly into Tier 1.

Switzerland (11th) presented the clearest example of the accuracy-vs-participation trade-off. With a pitch accuracy score of 87.4% – the second-highest in the entire dataset – the Swiss supporters and players sang very precisely. But a commitment rate of just 35% meant a significant portion of the anthem went unsung, limiting their overall score and placing them below nations that combined slightly lower accuracy with far greater participation.

Close Behind: The In-Tune Nations (Tier 2)

Tier 2 spanned 22 nations from Senegal (13th, 0.532 score) to Belgium (34th, 0.356 score) and covered a wide range of performance profiles. 

Senegal (13th, 0.532 score) and Qatar (14th, 0.525 score) led the tier, both displaying balanced accuracy-commitment profiles that characterized the stronger end of the middle of the field. Both also recorded maximum pitch stability scores. 

Several European nations occupied the lower half of Tier 2. France (26th, 0.430 score), Croatia (25th, 0.430 score), and Portugal (27th, 0.426 score) all scored within a narrow band, with relatively strong pitch accuracy scores undermined by low commitment rates. France recorded a commitment rate of just 37%, Portugal just 28% – meaning their supporters and players sang less than a third of the anthem. Portugal also achieved maximum pitch stability despite their lower overall placement.

Mexico ranked 29th with a 0.411 score. Their pitch accuracy of 77.0% was the highest in Tier 2, but a commitment rate of just 26% significantly limited their overall score.

Belgium finished 34th and last in Tier 2 with the lowest commitment rate of the tier at 24% – illustrating how even reasonable pitch accuracy cannot compensate when supporters and players are not actively singing.

Passion There, Pitch Less So (Tier 3)

Tier 3 covered nine nations from Austria (35th) to Brazil (43rd). These were nations where the analysis detected genuine singing effort, but pitch accuracy and commitment scores fell below the field average.

England ranked 40th with a 0.310 score. A commitment rate of 44% – reasonable by Tier 3 standards – was offset by a pitch accuracy of just 58.1%, one of the lower figures in the dataset. The Netherlands (39th) posted a near-identical profile, with a pitch stability score of 0.95 that ranked among the more stable performances in the tier.

The Brazilian supporters and players recorded a commitment rate of just 21% – only Tunisia (19%) scored lower across all 48 nations. Their pitch accuracy of 65.3% was not low by Tier 3 standards, but so little of the anthem was actively sung that it significantly limited their composite score.

Tunisia (42nd) recorded the lowest commitment rate of any nation across all 48 at just 19%. Despite a pitch accuracy of 66.0% that would have placed them comfortably mid-table on that measure alone, their score was held back by how little of the anthem their supporters and players actually sang.

The Bottom of the Table (Tier 4)

Tier 4 comprised five nations – Colombia, Spain, Argentina, Panama, and Ecuador – whose scores sat clearly below the rest of the field. All five recorded composite scores below 0.24.

Ecuador ranked last among all 48 nations with a 0.130 score – the lowest in the entire analysis, making them the least in-tune fandom at the 2026 World Cup. Both pitch accuracy (57.8%) and commitment (22%) were among the weakest recorded across all 48 nations.

Spain (45th, 0.219 score) was held back by a commitment rate of just 20% combined with the second-lowest pitch stability score in the dataset (0.76). It is worth noting that Spain's national anthem, the Marcha Real, has no official lyrics – however, the analysis measures pitch and vocal activity regardless of whether words are sung, meaning any humming, tonal chanting, or melodic participation by the crowd is captured and scored. 

Argentina (46th, 0.212 score) posted the lowest pitch stability score of all 48 nations (0.73), with a commitment rate of 41% that was not enough to compensate for weak accuracy. Panama (47th, 0.210 score) and Colombia (44th, 0.237 score) completed the tier, both recording commitment rates below 25% and pitch accuracy figures beneath the field average – with Colombia also recording the lowest pitch accuracy of any nation in the entire analysis at 52.7%. 

All in all, the singing contest has its winner now – Japan took that title with authority. Who takes the other trophy remains to be seen.

Methodology

• Data collection: June 2026.
• One anthem clip was collected per nation from 2026 World Cup matches – covering all 48 competing nations. The aim was to measure how precisely supporters and players sang their national anthem in tune, and how consistently they sang throughout it. 
• Six nations had a professional artist perform at their opening match rather than the supporters and players; for each of those nations, a rendition from a later group match was used instead, ensuring every score in the analysis reflects supporters and players rather than a soloist.
• The following steps were applied to each clip:
  • Each clip was trimmed to the sung portion only.
  • Demucs – a professional-grade audio source separation tool – was applied to isolate the vocal track from crowd noise, the stadium public address system, and the live band. Without this step, pitch detection would pick up instruments and ambient noise rather than the singing itself.
  • Pitch was extracted from the isolated vocal track using the pyin algorithm, producing 43 pitch readings per second. Each reading was assigned a confidence score, so moments where the microphone panned away or the signal was weak were automatically down-weighted.
  • Rather than scoring each clip as a single unit, the analysis was run across multiple overlapping three-second windows. The median score across all windows was taken as the nation's result for each component, meaning a single off-key moment or broadcast interruption cannot distort the overall score.
  • The analysis is reference-free: nations are not judged against sheet music or any external pitch standard. Pitch accuracy is measured relative to the crowd's own tuning – if supporters and players sing slightly sharp or flat as a group, they are not penalized for it. Only imprecision relative to themselves counts against them.
• Four components were measured and combined into a composite score:
  • Pitch accuracy (40%) – the percentage of sung moments that land within one fifth of a semitone of a note fitting the supporters and players' own tuning.
  • Commitment (40%) – the fraction of the clip's duration carrying detected singing. A nation whose supporters and players sing throughout scores higher than one where singing trails off or is largely absent.
  • Melodic richness (10%) – whether the singing contains genuine melodic movement. A monotone drone and random noise both score zero; real melodic variety scores one.
  • Pitch stability (10%) – how steadily notes are held between consecutive moments, rather than sliding or wavering.
• Scores were normalized across all 48 nations into a composite score from 0 to 1, where 1 is the highest possible. Nations are grouped into four tiers alongside the individual rankings – Tier 1 contains the highest-scoring nations, whose results are clearly and consistently above lower tiers; Tier 2 performs above the field midpoint; Tier 3 below it; and Tier 4 contains the lowest-scoring nations. Within each tier, the individual ranking still holds. 
• The robustness of the ranking was confirmed by re-running the analysis under multiple alternative weightings – Japan remained first in every variant tested, and approximately 96% of nation pairs maintained the same relative position regardless of weighting applied.
