Main evidence and numbers
| Figure | Wetin e concern | Important limit |
|---|---|---|
| 1.5% | Congenital amusia wey concern pitch, under the study criteria | E depend on screening and classification rules |
| About 20,000 participants | Size of the study first online sample | No be every participant enter every final analysis |
| Older 4% estimate | Earlier estimate from one test wey the authors discuss | No be one current diagnosis rate wey apply everywhere |
The prevalence paper use some objective tasks plus questionnaire. The main point be say poor score for one musical task no suppose make person automatically classify am as congenital amusia. The sample size na approximate because recruitment, exclusions and the groups wey contribute to particular analyses no dey the same. Peretz et al., 2017
Wetin congenital amusia mean for here?
The research dey look at lifelong difficulty with some parts of musical processing wey hearing loss or general cognitive problem no explain by themselves. The first case report and group study describe detailed assessments; dem no treat disliking music or singing off-key as the same thing as the condition. Peretz et al., 2002 Ayotte et al., 2002
The Montreal Battery dey assess different parts of musical ability. The people wey develop am and the later Montreal Protocol stress say tests na part of screening and assessment process, no be diagnosis wey one online test fit give alone. Consumer pitch game no automatically equal that protocol. Peretz et al., 2003 Vuvan et al., 2017
Why saying am about yourself fit mislead
People dey use tone deaf informally to describe plenty different experiences. Confidence, singing and pitch discrimination no be the same measurement. Prevalence estimate wey use one specific research definition no fit apply to everybody wey talk say dem no fit sing. The study criteria wey combine different measures matter because the informal label get wide meaning. Peretz et al., 2017 Vuvan et al., 2017
Wetin dey affect am?
Pitch and rhythm difficulty na the same thing?
No be always. Phillips-Silver and colleagues describe one beat-deaf case to show say difficulty to follow beat no be the same as problem to process melodic pitch. The review about synchronization too explain say rhythm perception and body movement coordination get different parts. Weakness for one small task no prove say person no fit do every kind musical task. Phillips-Silver et al., 2011 Repp et al., 2013
Age and sex fit tell person their own chance?
The prevalence study report say women make up somewhat higher proportion under the criteria, but that no create personal diagnosis rule. The way dem recruit and classify participants still determine the estimate. To use one percentage for another age group or casual online audience, more evidence go dey needed. Peretz et al., 2017
Wetin person fit really learn from test?
You fit see how you perform with the sounds, answer rules and device wey you use. If the difficulty happen plenty times, e fit make sense to understand am with more information, but short result no fit separate every source of error or show say na lifelong condition. The Montreal Protocol clearly treat even established musical test batteries as steps inside screening process. Vuvan et al., 2017
Reliability na different matter from whether real experimental task dey exist. The wider psychometric research show why result wey appear for group no guarantee say one short score go rank individuals consistently. This idea support caution, but e no deny wetin person dey experience with musical difficulty. Hedge et al., 2017
No study wey we cite show say this game dey cure congenital amusia or say short practice programme go remove am. The useful conclusion na prevalence estimate wey get clear definition, and understanding wetin different musical tasks dey measure. Peretz et al., 2017 Vuvan et al., 2017

Test for hearing musical tones
Try the test for hearing musical tones to check how you distinguish pitch and repeat rhythm. Treat each small task separately when you dey understand the result. E no be Montreal diagnostic protocol, and low score no prove congenital amusia or hearing loss.
Common questions
If I dey sing badly, e mean say I no fit hear musical pitch well?
The research definition no mean say those two things be the same. Singing and musical perception need different assessments. Vuvan et al., 2017
Which number correct: 1.5% or 4%?
Dem come from different methods and evidence. The large study report 1.5% under the criteria wey e combine, and e discuss the older 4% estimate. Peretz et al., 2017
Poor rhythm prove say person no dey hear pitch well?
No. The beat-deaf case and synchronization research show different parts of musical performance. Phillips-Silver et al., 2011 Repp et al., 2013
