Did Beethoven’s DNA Show He Wasn’t Musical? What the Study Actually Found

A genetic score for Beethoven’s beat synchronization ranked low against modern cohorts—but it was not a test of his musicianship or musical genius.

No. Beethoven’s DNA was used to estimate a genetic score for beat synchronization, not to measure his overall musicality or judge his compositions. That score ranked relatively low against two modern reference cohorts, but it cannot explain away his musical achievements.

What did Beethoven’s DNA study measure?

A 2024 study calculated a polygenic score for beat synchronization, a specific ability related to musicality. The score is a statistical estimate based on genetic associations found in earlier research; it is not a test of Beethoven’s rhythm in performance, composing ability, musical training, or talent. The authors described the analysis as “an example to illustrate the broader challenges of individual-level genetic predictions” (Wesseldijk and colleagues, Current Biology, 2024).

The genome data came from a separate 2023 study of hair attributed to Beethoven. Researchers examined eight locks and judged five authentic enough to use for genome sequencing. That project focused on health and ancestry, not on whether Beethoven was musical (Begg and colleagues, Current Biology, 2023).

Where did Beethoven’s beat-synchronization score rank?

The 2024 analysis compared Beethoven’s score with two modern reference cohorts. The reported percentiles describe his position in those datasets for the modeled trait—not a percentage of musical ability.

#1 Best Overall
Reference cohort Reported percentile What it means
STAGE 9th His estimated beat-synchronization score was lower than most scores in this modern comparison cohort.
Vanderbilt BioVU 11th His estimated score was also relatively low in this second modern comparison cohort.

These are two cohort-specific comparisons, not direct musicality tests or rankings of Beethoven’s musicianship. They should not be averaged into a single score or treated as independent demonstrations of his musical ability (Wesseldijk and colleagues, 2024).

Why a low genetic percentile does not mean Beethoven lacked musical talent

A score is not the trait itself

A polygenic score combines many genetic associations into an estimate. It does not record what a person actually did, and it cannot establish how well Beethoven kept a beat, learned music, performed, or composed. Beat synchronization is only one facet of musicality; it is not equivalent to musical achievement.

The underlying prediction was modest

In the underlying study, the musicality index predicted musicianship status with an R² of 2%; estimates for a small range of music-related skills were between 1% and 3%. Those figures describe prediction across study participants, not the amount of Beethoven’s talent or the certainty of his individual score. The reported SNP-based heritability estimate for the relevant measures was 13–16%; heritability describes variation in a population under particular conditions, not a fixed limit on an individual (Wesseldijk and Henechowicz, 2024).

Genetic and environmental context matters

Polygenic indices capture only part of the genetic contribution to complex traits and may omit rare variants. Their predictive performance depends on factors including the size and power of the discovery study, how the trait is defined, ancestry, and environmental influences. A score developed from population associations therefore cannot serve as a complete account of one person’s abilities or life.

What the original Beethoven genome study did—and did not—say

The 2023 genome study investigated Beethoven’s health and family history. It reported genetic predisposition to liver disease, evidence of hepatitis B infection, and an extra-pair paternity event somewhere in the composer’s direct paternal line. Those findings are separate from the later beat-synchronization analysis; they do not explain its score (Begg and colleagues, 2023).

What to take away from the headline

The result is an instructive mismatch: Beethoven’s estimated genetic score for one narrowly defined musical trait was low relative to modern cohorts, while his documented musical legacy is exceptional. The study’s point is not that DNA disproves his musicianship. It illustrates why a polygenic score should not be treated as a verdict on an individual.
