Engeri y'okutegeeramu ebivudde mu kigezo

  • Entono y'entondo gy'owulidde: epimibwa mu cents. Ekifo ky'entondo (semitone), ekiri wakati w'ebyuma bibiri ebiriraanye ku piano, kiba cents 100. Kino kye kifo ky'osobodde okwawula emirundi nga 7 ku 10. Ekifo ekitono kiraga okuwulira obulungi okusingawo.
  • Entongooli z'owulidde obulungi: omuwendo gw'entongooli 5 ze wakubye n'oziddamu okumpi n'engeri gye zaawuliramu. Obwangu bw'okukuba tebubalwa: okukuba kwo tukugolola kukwatane n'obuwanvu bw'entongooli nga tetunnagerageranya.
  • Ensobi mu kiseera ky'entongooli: ku kigero, buli bbanga wakati w'okukuba kwo liva wala kutya ku bbanga ly'entongooli, nga lipimibwa mu kikumi.
  • Entondo ze wategeezezza (ekitundu eky'okwesalirawo): omuwendo gw'entondo ez'omu bubwe ze wategeezezza amannya gazo bulungi. Entondo esobye ekifo kya semitone kimu ewa empeera ey'ekitundu mu kikumi, ng'abanoonyereza bwe bazibalira [1].

Okutwalira awamu, okutu kuba kulungi kutya?

Ekifo ky'entondo (semitone) kiba cents 100. Mu kunoonyereza okw'omu labalatoli, abantu aba bulijjo abatali bayimbi basobola okuwulira enjawulo y'entondo nga eri wakati wa cents 12 ne 35, ate abayimbi abatendekeddwa basobola n'eyo eya cents nga 2 ne 17 [2][3][4]. Okutendekebwa kuyamba nnyo: abatali bayimbi batuuka ku mutindo gw'abayimbi oluvannyuma lw'essaawa 4 okutuuka ku 8 ez'okutendekebwa [2]. Obuzibu obw'amazima obw'okuwulira amaloboozi (amusia ey'obuzaale) tebusaasaana, bukwata ku bantu abakulu nga 1.5% [5].

Ebimanyiddwa mu bufunze

  • Obuzibu bw'okuwulira amaloboozi tebusaasaana: abantu abakulu nga 1.5% balina amusia ey'obuzaale, obuzibu obw'okuwulira entondo ez'ennyimba obumala obulamu bwonna, okusinziira ku kunoonyereza okw'oku yintaneeti okwawekenneenya abantu abakulu nga 16,600 [5]. Abantu bangi nnyo abalala bagamba nti "tebasobola kuyimba".
  • Okutendekebwa kulongoosa okuwulira entondo: abayimbi b'ennyimba ez'ekikula ekya kalaasika baatandika n'obusobozi bw'okwawula entondo obulungi emirundi egisukka mu 6 okusinga abatali bayimbi. Abatali bayimbi baakendeezaawo enjawulo oluvannyuma lw'essaawa 4 okutuuka ku 8 ez'okutendekebwa [2].
  • Okumanya entondo entuufu ennyo kisinziira ku kutendekebwa kw'obuto n'olulimi: mu bayizi b'ennyimba abaayogera okutendekebwa nga bali mu myaka 4 okutuuka ku 5, nga 60% mu Beijing ne 14% mu ssomero ly'ennyimba mu Amerika baali bamanyi entondo entuufu ennyo [6].
  • "Omuntu 1 mu 10,000" muwendo ogutali mukakafu: omuwendo ogwogerwako ennyo ogw'okumanya entondo entuufu ennyo gwava mu kuteebereza okwa 1955 okwesigamiziddwa ku bayimbi omunoonyereza omu be yali asisinkanye, so si ku bantu abalondebwa mu ngeri ey'obutaliimu kusosola [7].
  • Buli muntu akuba entongooli nga bukyali: abantu abasinga obungi bwe bakuba entongooli okugoberera eddoboozi, bazikuba nga bali mu maaso katono, ekiseera ekitundu kya sekondi [8].

Engeri ekigezo ky'obuzibu bw'okuwulira amaloboozi gye kikolamu

  1. Kebera eddoboozi. Owulira entondo nnya nga zigenda zeeyongera obugulumivu, osobole okuteekawo eddoboozi erikusanyusa. Okuba ery'amaanyi si kirungi okusingawo.
  2. Waggulu oba wansi? Eddoboozi libaako emirundi ebiri, emu n'eddirira endala. Ery'okubiri lyali waggulu oba wansi? Entondo y'eddoboozi erisooka ekyuka buli mulundi, wakati wa 330 ne 660 Hz, kale tosobola kuyiga ntondo emu etakyuka. Entono y'ekifo etandika ku cents 100. Bw'oddamu bulungi emirundi ebiri egiddiring'ana, ekifo kikendeera; bw'osobya, kyeyongera. Enkola eno eya "2 wansi, 1 waggulu" eteekawo ekifo mw'oba otuufu nga 71% ku biseera [9]. Ekoma oluvannyuma lw'ebifo eby'okukyukirako 10, era ekivudde mu kigezo kibalibwa nga kigattiddwa okuva ku bifo eby'enkomerero 6.
  3. Entongooli. Entongooli ennyimpi ey'okunyiga esooka okuwulirwa emirundi 2; olwo ogikube ogiddemu. Waliwo entongooli 5.
  4. Ekigezo ky'okumanya entondo entuufu ennyo (ky'oyagala). Entondo ez'omu bubwe 12, nga tewali ntondo ya kugererako era tewali kukubuulira oba otuufu. Tuuza buli emu ku kibalirizo kya piano.

Buli ddoboozi likolebwa mu pulogulaamu ya bulawuza yo; tewali maloboozi gakozesebwa agaasooka okukwatibwa.

Ekigezo ky'okumanya entondo entuufu ennyo

Okumanya entondo entuufu ennyo (absolute pitch) kwe kumanya erinnya ly'entondo nga tonnawulira ntondo ya kugererako. Mu kunoonyereza kumu okunene okwa yintaneeti, abantu abaali nakwo baafuna obubonero obusinga wala ku bwa buli muntu omulala; obubonero bwakola ebibinja bibiri ebyawukana, nga waliwo abantu batono wakati waabyo [1]. Okusaasaana kwakwo kusinziira ku bantu be weebuuza: abayizi b'ennyimba mu Japan nga 30% n'abo mu Poland nga 7% baayita ekigezo ekyali ekikaluba [7], era okutendekebwa okw'obuto n'olulimi olulina entondo ez'enjawulo byongera emikisa gy'okukufuna [6]. Abantu abasinga obungi, n'abayimbi abasinga obulungi, balina okuwulira okw'enjawulo (relative pitch): bawulira ebifo wakati w'entondo, so si ntondo zennyini.

Ebintu ebikosa ebivudde mu kigezo kyo

  • Okutendekebwa mu nnyimba. Okumala emyaka ng'okuba ekyuma ky'ennyimba oba okuyimba kiyamba nnyo okuwulira obulungi ebifo by'entondo [2][3].
  • Okwegezangamu ekigezo kino kyennyini. Ebifo by'entondo bikendeera mu kugezaako okusooka, ne mu kiseera ky'okugezesa kumu [2]. Geraageranya okugezaako kwo okuddako n'okwo kuno.
  • Ebyuma by'okuwuliriza n'ekisenge. Ebyuma by'okuwuliriza n'ekisenge ekisirifu biyamba. Ebyuma by'essimu ebitono biyinza okulemesa okuwulira amaloboozi ag'ebitonotono.
  • Okussaayo omwoyo n'obukoowu. Okuta okussaayo omwoyo mu kugezaako kumu kuleetera ekifo ky'entondo okwongera obunene.
  • Empisa z'okukuba entongooli. Abantu batera okugoberera entongooli ennyangu, ng'okuwooma kw'eddoboozi eddene kumala emirundi ebiri obuwanvu bw'eddoboozi ettono, bwe baziddamu okukuba [10]. Abantu bonna batera okukola ensobi ezimu.

Ekigezo kino kye kisobola n'ekitayinza kukubuulira

Ekigezo kya Helibrain eky'obuzibu bw'okuwulira amaloboozi muzannyo gwa kutendeka kutu ogusanyusa nga gwesigamiziddwa ku mirimu egyakozesebwa mu kunoonyereza. Si kigezo kya kuwulira, si kukebera amusia, era si bigezo bya kunoonyereza ebikozesebwa okugikebera (nga Montreal Battery of Evaluation of Amusia) [11]. Eddoboozi lya bulawuza n'ebyuma ebiwuliriza si byuma bya labalatoli, kale ebibalo byo bitwale ng'ebiteeberezebwa.

Bw'oba weeraliikirira okuwulira kwo, gamba ng'ebigambo bwe biwulikika nga bikutte, laba omusawo oba omukugu mu kuwulira.

Ebibuuzo ebibuuzibwa ennyo

Ntegeera ntya oba nnina obuzibu bw'okuwulira amaloboozi?

Bw'osobola okwawula eddoboozi erisinga obugulumivu mu maloboozi abiri agawukana ekifo kya semitone (cents 100), kiba kisoboka nnyo nti tolina buzibu bwa kuwulira maloboozi: abantu abasinga obungi basobola okuwulira ebifo ebitono ennyo [2][4]. Obuzibu obw'amazima obw'okuwulira amaloboozi, amusia ey'obuzaale, bukwata ku bantu abakulu nga 1.5% [5] era bukeberebwa n'ebigezo by'okunoonyereza ebimpi obuwanvu. Ekigezo kya Helibrain kikuyamba okufunako endowooza esooka, naye tekikukebera oba olina obulwadde.

Abantu abameka ku kikumi abalina obuzibu bw'okuwulira amaloboozi?

Abantu abakulu nga 1.5% balina amusia ey'obuzaale, okusinziira ku kunoonyereza okw'oku yintaneeti okwawekenneenya abantu abakulu nga 16,600, ab'emyaka 18 okutuuka ku 65 [5]. Okunoonyereza okukadde okwa 1980 kwagamba nti 4%, nga bakozesa ekigezo eky'enjawulo n'ennyonnyola eyali ennyangu okutuukiriza [12]. Abantu bangi nnyo balowooza nti balina obuzibu bw'okuwulira amaloboozi kubanga tebamanyi kuyimba bulungi; okuyimba n'okuwulira entondo bukugu bwa njawulo.

Okumanya entondo entuufu ennyo kutono kutya?

Okumanya entondo entuufu ennyo kutono mu bantu bonna, naye tewali muntu amenye muwendo gwennyini ogw'obutono bwakwo. Omuwendo ogumanyiddwa ogwa "1 mu 10,000" kuteebereza kwa dda okwesigamiziddwa ku bujulizi obunafu [7]. Mu bayizi b'ennyimba omuwendo guva ku bitundu bitonotono ku kikumi okutuuka nga 30%, okusinziira ku kiseera okutendekebwa we kwatandikira n'olulimi [6][7].

Omuntu omukulu asobola okuyiga okumanya entondo entuufu ennyo?

Abantu abakulu basobola okuyiga okumanya entondo ezimu nga begezangamu nnyo, naye okumanya entondo entuufu ennyo kukwatagana nnyo n'okutendekebwa mu nnyimba mu buto [6]. Abayimbi abasinga bakozesa okuwulira okw'enjawulo, okuwulira ebifo wakati w'entondo, era kwo kweyongera okulungi olw'okwegezangamu mu myaka gyonna [2].

Obubonero obulungi mu kigezo ky'entondo bwe buva ku ki?

Mu kunoonyereza okw'omu labalatoli, abatali bayimbi batera okuwulira enjawulo ya cents nga 12 okutuuka ku 35, ate abayimbi abatendekeddwa nga 2 okutuuka ku 17 [2][3][4]. Ebivudde mu kigezo ebiri wansi wa cents 10 biraga okutu okulungi ennyo. Ekivaamu ekisukka cents 100 (ekifo kya semitone) tekitera kubaawo, era kiba kirungi okuddamu okugezaako mu kisenge ekisirifu ng'oyambadde ebyuma by'okuwuliriza.

Ekigezo kya Helibrain eky'obuzibu bw'okuwulira amaloboozi kya bwereere ddala?

Yee. Ekigezo kino n'ebivudde mu kyo byonna bya bwereere: tekyetaagisa kwewandiisa, email, oba kusasula. Helibrain efuna ssente okuva mu pulogulaamu yaayo erina enteekateeka ey'obwereere n'endala ezisasulwa; teweetaaga pulogulaamu eyo kukola kigezo.

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.
