Hou tae read yer result

  • Weeest pitch step ye heard: in cents. A semitone, the step atween twa neist keys on a pianie, is 100 cents. This is the step ye could tell sindert aboot 7 times oot o 10. Wee'er is finer.
  • Beats matched: hou mony o the 5 rhythms ye tapped back close. Tempo disnae count: yer taps are stretched tae the rhythm's length afore comparin.
  • Rhythm timing error: on average, hou far each gap atween yer taps was fae the rhythm's gap, in percent.
  • Notes named (optional pairt): hou mony single notes ye named exactly. A note ae semitone oot earns pairt credit in the percentage, the wey researchers score it [1].

Hou guid is a ordinar ear?

A semitone is 100 cents. In lab studies, ordinar non-musicians can hear pitch differences o roond 12 tae 35 cents, an trained musicians differences as wee as aboot 2 tae 17 cents [2][3][4]. Practice helps a hantle: non-musicians reached musicians' level efter 4 tae 8 hours o trainin [2]. True tone-deefness (congenital amusia) is rare, aboot 1.5% o adults [5].

Quick facts

  • Tone-deefness is rare: aboot 1.5% o adults hae congenital amusia, a lifelong trouble wi musical pitch, in an online study that analyzed aboot 16,600 adults [5]. Mony mair fowk say they "cannae sing".
  • Trainin sharpens pitch: classical musicians' pitch thresholds stertit mair than 6 times finer than non-musicians'. Non-musicians closed the gap efter 4 tae 8 hours o practice [2].
  • Perfect pitch depends on early trainin an leid: amang music students that stertit lessons at age 4 tae 5, aboot 60% in Beijing an 14% at a US conservatory had perfect pitch [6].
  • "1 in 10,000" is a weak nummer: the aft-quoted rate o perfect pitch comes fae a 1955 estimate based on the musicians ane researcher happened tae meet, no a random sample [7].
  • Ilkaebody taps early: whan tappin alang tae a beat, maist fowk tap a few tens o milliseconds afore it [8].

Hou the tone-deef test warks

  1. Soond check. Ye hear fower notes gaun up, sae ye can set a comfortable volume. Loud is nae better.
  2. Heicher or laicher? Twa tones play, ane efter the ither. Wis the second heicher or laicher? The first tone's pitch chynges ilka time, atween 330 an 660 Hz, sae ye cannae learn a fixed note. The step sterts at 100 cents. Efter twa richt answers in a row it gets wee'er; efter a wrang answer it gets bigger. This "2-down, 1-up" rule settles whaur ye are richt aboot 71% o the time [9]. It stops efter 10 turnin-points, an yer result is the average o the last 6.
  3. Rhythm. A short click rhythm plays 2 times; syne tap it back. There are 5 rhythms.
  4. Perfect pitch test (optional). 12 single notes, wi nae reference note an nae feedback. Name ilk ane on the keyboard.

Ilka soond is made in yer browser; there are nae recordings.

Perfect pitch test

Perfect (absolute) pitch is namin a note withoot hearin a reference note first. In ae large online study, fowk that had it scored far abuin itherbody; scores formed twa sindert groups, wi few fowk atween [1]. Hou common it is depends on wha ye speir: aboot 30% o Japanese music students an 7% o Polish music students passed a strict test [7], an early lessons an a tone leid mak it mair likely [6]. Maist fowk, includin maist guid musicians, hae relative pitch instead: they hear the steps atween notes, no the notes theirsels.

Whit affects yer result?

  • Musical trainin. Years o playin an instrument or singin mak pitch steps muckle easier tae hear [2][3].
  • Practice on the task itsel. Thresholds drap ower the first runs, even in ae session [2]. Compare yer neist try wi this ane.
  • Heidphones an room. Heidphones an a quiet room help. Wee phone speakers can mak laich tones hard tae hear.
  • Attention an weariness. A lapse o attention on ane trial maks the step jump up again.
  • Rhythm habits. Fowk tend tae drift tae simple rhythms, like lang notes twice as lang as short anes, whan tappin back [10]. Some "error" is normal for ilkaebody.

Whit this test can an cannae tell ye

The Helibrain tone-deef test is a fun ear gemme based on research tasks. It isnae a hearin test, nae a diagnosis o amusia, an nae the research batteries uised tae diagnose it (sic as the Montreal Battery of Evaluation of Amusia) [11]. Browser audio an speakers arenae lab gear, sae tak yer nummers as rough.

If ye're worried aboot yer hearin, for example if speech soonds muffled, see a doctor or an audiologist.

Aften speired questions

Hou dae A ken if A'm tone-deef?

If ye can tell whilk o twa tones is heicher whan they are a semitone (100 cents) sindert, ye are gey likely no tone-deef: maist fowk can hear muckle wee'er steps [2][4]. True tone-deefness, congenital amusia, affects aboot 1.5% o adults [5] an is diagnosed wi langer research tests. The Helibrain tone-deef test gies ye a first idea, no a diagnosis.

Whit percentage o fowk are tone-deef?

Aboot 1.5% o adults hae congenital amusia, efter an online study that analyzed aboot 16,600 adults aged 18 tae 65 [5]. An aulder study fae 1980 put it at 4%, uisin a different test an a looser definition [12]. Far mair fowk believe they are tone-deef acause they cannae sing weel; singin an hearin pitch are different skills.

Hou rare is perfect pitch?

Perfect pitch is rare in the general population, but naebody has measured exactly hou rare. The famous "1 in 10,000" figure is an auld estimate wi weak data ahint it [7]. Amang music students the rate rins fae a few percent tae aboot 30%, dependin on hou early lessons stertit an on leid [6][7].

Can ye learn perfect pitch as an adult?

Adults can learn tae recognize some notes wi a hantle o practice, but true perfect pitch is strongly linked tae music lessons in early bairnheid [6]. Relative pitch, hearin the steps atween notes, is whit maist musicians uise, an it improves weel wi practice at ony age [2].

Whit's a guid score on the pitch test?

In lab studies, non-musicians typically hear differences o aboot 12 tae 35 cents an trained musicians aboot 2 tae 17 cents [2][3][4]. A result unner 10 cents is a gey fine ear. Ower 100 cents (a semitone) is unuisual an worth anither try in a quiet room wi heidphones.

Is the Helibrain tone-deef test really free?

Aye. The test an yer full result are free: nae sign-up, nae email, nae payment. Helibrain maks siller fae its app, that has a free plan an paid plans; ye dinnae need the app tae tak the test.

Common questions

How this test works

This ear game has two parts and an optional third. First, two tones play and you say whether the second was higher or lower. The difference shrinks after two right answers and grows after a mistake, until it settles near the smallest step you can hear. That step, in cents, is your main score. Second, you tap back 5 short click rhythms. Third, you can name 12 single notes. This up-down method was described in 1971.
