    What’s Your Rhythm Level?

    How good is my sense of rhythm?

    Probably close to everyone else’s, and this rhythm test tells you exactly where you stand. In the 2024 adult norms of BAASTA, a research battery for timing, the middle of 100 adults without music training heard a beat as off once it came about 70 milliseconds early — 11.6% of the 600 ms between beats. The best 5% caught a slip of about 32 ms or less.

    This test measures that one skill, the way an eye chart measures sight. It plays the same sounds as BAASTA’s anisochrony detection task: five piano-like tones at C6, 600 ms apart, and sometimes the fourth comes early. You say even or off. On level 1 the fourth beat is 180 ms early; the slip halves every three levels, down to about 14 ms on level 12. About four in ten sequences are perfectly even, so answering “off” every time ends the test early. Every off sequence you catch takes you down a row; the first miss gives you another go at the same row, the second ends the run. The last row you passed is converted by simulation to BAASTA’s threshold criterion, so you can see where you stand among those 100 adults.

    It is not a hearing test and not a diagnosis of anything. It measures how finely you hear timing, not whether you can clap, dance or play in time. One short run lands within about a level either way, and the phone, Bluetooth headphones (which can smear timing) and a noisy room all move the number.

    What the rhythm test measures

    One skill, measured like an eye chart: the smallest slip in an even beat that you can still hear.

    The task

    • Five piano-like tones at C6 (1,047 Hz), 600 ms apart: the stimulus of BAASTA’s “anisochrony detection with tones” (Dalla Bella et al., 2024)
    • Is the beat even, or does the fourth tone come early? An example of each plays before you start
    • 12 levels, from 180 ms early (30% of the gap) down to about 14 ms, the slip halving every three levels
    • About four in ten sequences are even; calling an even one off counts as a miss, like missing an early beat
    • Two misses in all: the first gives you another go at the same row, the second ends the test. Replay any sequence before you answer

    Your result

    • Your rhythm level (1–12) and the slip you can hear, in milliseconds and as a share of the gap between beats
    • Where you stand among BAASTA’s 100 adults, aged 18 to 87, without music training: the share of them you hear finer than
    • Reference points from the same norms: the best 5% (5.3% of the gap), the median (11.6%), ages 22–29 (10.1%) and ages 55–87 (14.4%)
    • A separate mark for musicians: 41 pianists and brass players at about 3.7% of the gap in van Vugt & Tillmann (2014), shown for reference and not ranked against
    • Your limit in everyday terms: a fraction of a beat at 120 BPM, how far sound travels in that time, and frames of 60 fps video
    • A row-by-row record, including how many even sequences you heard as off, a shareable card, and a link that challenges a friend to beat your level

    Before you start

    • Sound on; wired headphones are best, and a quiet room helps
    • On an iPhone, switch off silent mode first
    • About three minutes
    • Your answers are scored in your browser; a challenge link carries your level, and the name you add, in the address after the #

    Rhythm test FAQ

    Is this test free? Do I need to sign up to see my result?

    Yes, it’s free, and there’s nothing to sign up for: no account, no email, no payment. Your result appears on this page the moment you finish, and you can share it or play again straight away.

    How do I know if I have good rhythm?

    Hearing rhythm well means noticing when a beat lands even slightly off. In BAASTA’s 2024 norms, the middle adult without music training noticed a beat about 70 ms early out of 600 ms, and the best 5% noticed about 32 ms. This rhythm test measures your own limit on the same five-tone task and places it among those 100 adults.

    How accurate is an online rhythm test?

    This rhythm test is a rough but real measurement. It uses BAASTA’s published stimulus and converts your level to BAASTA’s 70.7% threshold by simulation. Because a run is short, about 15 sequences against the 27 or so of a lab staircase, one result can land about a level away from your true threshold either way. Two or three runs say more than one.

    What is a normal rhythm threshold?

    In the BAASTA adult norms (Dalla Bella et al., 2024), the median listener heard the fourth of five beats as early once it was 11.6% of the 600 ms gap ahead, about 70 ms. Men and women did not differ. Medians by age were 11.1% at 18–21, 10.1% at 22–29, 10.5% at 30–54 and 14.4% at 55–87, so the change with age is small until later life.

    Do musicians hear rhythm better?

    Yes, on average. In van Vugt and Tillmann’s 2014 study, with a similar five-tone task, 41 pianists and brass players noticed a shift of about 3.7% of the gap between beats, against 9.7% for 20 non-musicians (medians recomputed from the study’s open data). The study compared groups, so it does not show how much practice changes one person.

    Does this test whether I can keep a beat?

    No. This rhythm test measures perception: how small a slip in an even beat you can hear. Keeping a beat, by tapping, clapping or dancing, also depends on moving in time, which this test does not measure. Research batteries like BAASTA test the two separately.

    Why did I get a different rhythm level the second time?

    A short run is noisy, and the setup matters. Bluetooth headphones can smear timing, phone speakers and noisy rooms make the beats harder to hear, and a moment of distraction costs one of your two misses. The best of a few runs, on wired headphones in a quiet room, is closest to what your ears can do.

    Is this a hearing test or a diagnosis?

    No. The rhythm level compares your timing perception with 100 adults in a published study; it does not check hearing and does not diagnose any condition. If you are worried about your hearing, a hearing check by a professional is the right test.

    Where the numbers come from

    Percentiles compare your threshold with the 100 adults without music training in the BAASTA norms (Dalla Bella et al., 2024, supplementary table S12), who did the same five-tone task on headphones. Your level is converted to their 70.7% threshold by simulation. The musicians’ mark is recomputed from van Vugt & Tillmann’s open data and is not part of the ranking. The site does not publish its own players’ data.

    How the rhythm level is scored

    Anisochrony detection

    The listener hears an isochronous (evenly spaced) sequence or one with a single tone shifted early, and says which. BAASTA uses five tones with the fourth shifted; this test copies that stimulus.

    Threshold

    BAASTA reports the shift a listener hears as irregular 70.7% of the time, found with an adaptive staircase. This test’s level is the last row passed before the second miss, multiplied by about 1.11 so that it matches that criterion in simulation.

    Even (catch) sequences

    Even sequences mixed into the run keep the score honest: calling one of them off costs a miss, so someone who says “off” to everything stops by level 6 at the latest.
