Cov yuam sij Dawb nrog cov npe tuaj yeem hu tau yooj yim los ntawm txhua tus neeg nruab nrab, tab sis qhov "nruab nrab" tuaj ntawm qhov twg? Txhawm rau ua qhov no, muaj cov cim tsis sib xws hauv suab paj nruag. Nrog lawv cov kev pab, muaj ntau ntau lub suab xaiv, tus naj npawb ntawm cov ntawv uas koj tuaj yeem tsim kom muaj kev sib xyaw ua ke nce.

Notes and keys

Yog tias koj saib cov keyboard piano, koj yuav pom tias nws tau muab faib ua vaj huam sib luag - octaves. Txhua tus muaj 12 lub suab. Tsuas yog 7 tus paub: do, re, mi, fa, ntsev, la, si. Cov no yog cov suab nrov nrov, dag raws nraim ntawm cov yuam sij dawb - nws nyuaj rau ua yuam kev.

Cov yuam sij tau teeb tsa hauv txoj hauv kev los ua kom sau thiab ua suab paj nruag kom yooj yim li sai tau. Lawv muab systematization, lawv suab txog tib yam, tsuas yog nyob rau hauv sib txawv heights. Tsuas yog qhov loj thiab me tuaj yeem paub qhov txawv yooj yim - lawv suab "kev lom zem" thiab "tu siab" raws.

Muaj 2 tus yuam sij ntawm lub suab tseem ceeb:

• C major;
• Ib tug me.

Qhov no txhais tau tias thaum ua si thiab sau rau hauv cov yuam sij no yuav tsis muajcov yawm sij dub tau siv - lawv tsis nyob hauv qhov ntsuas. Lawv suav hais tias yog sib npaug, vim lawv muaj tib lub suab nrog cov cim sib txawv thiab tonics.

Ib nrab tone

Qhov "kev ncua deb" ntawm tag nrho cov ntawv tseem ceeb yog ib lub suab nkaus xwb, tshwj tsis yog mi-fa thiab si-do, qhov sib nrug tsuas yog ib nrab ntawm lub suab. Qhov no yog li cas tus qauv fret tsim:

• major (txav mus rau): ob lub suab, semitone, peb lub suab, semitone;
• me (tsiv los ntawm A): ib lub suab, semitone, ob lub suab, semitone, ob lub suab.

Lwm tus yuam sij yuav zoo ib yam, tab sis cov suab pib tsis txaus rau qhov no. Rau qhov no, muaj cov yuam sij dub uas pab tsim cov nplai los ntawm ib qho tonic. Lawv faib cov octave rau hauv semitones qhov xav tau (tshwj tsis yog rau ob qho uas twb muaj lawm), khaws cia qhov sib piv ntawm cov suab. Cov ntawv sau ntxiv no tsis muaj npe, lawv txiav txim siab los ntawm kev nce lossis poob ntawm ib qho ntawm cov ntawv tseem ceeb. Nws tseem yuav cim nws li cas.

Lub luag haujlwm ntawm kev sib tsoo hauv suab paj nruag

Tsuas yog kom tau txais cov halftones tsim nyog rau kev ntxhov siab, tsim cov cim tsis sib xws. Muaj 5 ntawm lawv hauv cov suab paj nruag:

• flat - ib nrab tone down;
• bekar - tshem tag nrho cov ntse thiab flats;
• ntse - ib nrab kauj ruam;
• ob ntse - nce los ntawm lub suab nrov;
• ob tiaj - txos ib lub suab.

Txhua qhov kos npe tuaj yeem raug ntaus nqi rau daim ntawv tseem ceeb los ntawm kev muab tso rau ntawm lub stave pem hauv ntej ntawm nws nyob rau tib theem (ntawm kab, hauv qab kab, saum kab). Lub ntsiab lus ntawm lub suab yog tsim los ntawm lub ntsiab npenco ntsoov + lub npe ntawm lub cim nyob rau hauv pem hauv ntej ntawm nws. Piv txwv li, tsa ib nrab lub suab rau - kom ntse, qis dua ib nrab lub suab rau mi - mi tiaj, thiab lwm yam.

Ib zaug txaus

Accessions hauv cov yuam sij tsim lub kaw lus, raws li tau hais lawm. Txhawm rau ua kom yooj yim, lawv tuaj nrog lub tswv yim ntawm kev tso cov cim ntawm tus yuam sij - thaum pib ntawm kab. Qhov no txhais tau hais tias lub cim tso rau ntawm lub stave siv rau txhua daim ntawv ntawm kab ntawd. Nws tuaj yeem nyob tsis hloov pauv thoob plaws hauv qhov muaj pes tsawg leeg yog tias tsis muaj kev hloov pauv hauv qhov tseem ceeb lossis suav nrog cov cim ntxiv. Lawv ua nyob rau hauv tag nrho cov octaves thiab lub suab (yog hais tias txoj hauj lwm yog orchestral) tib txoj kev, mus txog rau thaum thawj kev hloov kho.

Tus lej ntawm cov cim ntawm tus yuam sij yog nyob ntawm lub tonality, uas tuaj yeem muaj lub npe thiab ua raws li lub suab. Qhov yooj yim tshaj plaws C loj thiab teeming E-flat loj tseem muaj tib qhov kev txiav txim ntawm tones thiab semitones.

Staging rules

Kev kaw thiab kev teeb tsa ntawm kev sib tsoo hauv cov ntawv yog ua raws cov cai nruj:

• txawm qhov ntse lossis flats yog siv rau hauv tib tus yuam sij, muaj cov cim rov qab hauv tus yuam sij yog qhov tsis lees txais;
• yog ib txwm muab tso rau sab xis ntawm tus yuam sij;
• sharp order - fa, do, sol, re, la, mi, si;
• flat - si, mi, la, re, sol, do, fa.

Nkag mus rau hauv kev xav suab paj nruag, qhov sib lawv liag ntawm cov yuam sij txav mus rau hauv lub voj voog ntawm plaub thiab thib tsib. Rau sharps - nce ib tug thib tsib, pib los ntawm C loj, uas yog, txhua tus tshiab tshwm nyob rau hauv lub thib tsib kauj ruam piv rau yav dhau los. Rau flats - tib yam, tsuas yog hauv quarts(theem plaub). Qhov no qhia tau meej tias yog lub voj voog.

Qhov tseem ceeb tshaj plaws yog kom nco ntsoov tias qhov nyuaj ntawm kev ua haujlwm tsis yog nyob ntawm kev sib tsoo. Cov no tsuas yog "icons" uas koj yuav tsum nco ntsoov thiab nco ntsoov thaum koj txheeb xyuas qhov muaj pes tsawg leeg.

Nws tuaj ntawm no li cas?

Nws yog ib qho uas pom lub ntsej muag ntse lossis tiaj tus hauv daim ntawv suab paj nruag tam sim ua ntej lub suab, txawm tias qhov tseem ceeb tau teeb tsa. Xws li "cov qhua" yog hu ua random accidentals thiab siv tau tsuas yog mus txog rau thaum xaus ntawm barline. Bekar nyob rau hauv cov ntaub ntawv no tuaj yeem tshem tawm cov cim tseem ceeb lossis, yog tias nws tsis tas yuav tsum tau ua ntej qhov kawg ntawm qhov ntsuas, teeb tsa random.

Piv txwv li, hauv tus yuam sij ntawm F minor 4 flats: si, mi, la, re. Rau qhov dynamism ntawm kev ua haujlwm, tus neeg sau tuaj yeem hloov kho qhov ntsuas qhov yooj yim los ntawm kev ua si ib lub suab yam tsis muaj kev txo qis. Txhawm rau qhia qhov no thaum sau ntawv, yuav muaj tus thaub qab nyob rau pem hauv ntej ntawm ib daim ntawv tshwj xeeb. Nyob rau hauv tsis muaj cov ntaub ntawv yog nws ntse, txij li thaum sawv los ntawm ib tug semitone (rov qab los ntawm daim ntawv rau nws thawj daim ntawv) yog nqa tawm tsuas yog los ntawm kev tshem tawm lub tiaj tus. Thiab nws tsuas ua haujlwm hauv ib qho kev ntsuas.

Nrog 12 lub suab, cov suab paj nruag yog qhov nthuav ntau dua li nws yuav muaj xya lub suab. Muaj ntau qhov sib txawv, koj tuaj yeem hloov kho thiab nthuav tawm ntau dua hauv cov suab paj nruag. Qhov tseeb, qhov no yog qhov xwm txheej yog rau.
