Kodi mungapeze bwanji lingaliro la bass ya accordion?
Mabasi a accordion ndi matsenga akuda kwa anthu ambiri ndipo nthawi zambiri, makamaka kumayambiriro kwa maphunziro a nyimbo, amakhala ovuta kwambiri. Accordion palokha si imodzi mwa zida zosavuta ndipo kuti muzisewera muyenera kuphatikiza zinthu zambiri. Kuphatikiza pa dzanja lamanja ndi lakumanzere mogwirizana, muyeneranso kuphunzira momwe mungatambasulire bwino ndikupinda mavuvu. Zonsezi zikutanthauza kuti zoyambira sizomwe zimakhala zosavuta, koma tikakwanitsa kumvetsetsa zoyambira izi, chisangalalo chosewera chimatsimikizika.
Nkhani yovuta kwambiri kwa munthu yemwe wayamba kuphunzira ndi mbali ya bass, yomwe timakakamizika kusewera mumdima. Sititha kuwona kuti ndi batani liti lomwe timasindikiza, kupatula pagalasi 😊. Chifukwa chake zitha kuwoneka kuti kuti munthu aphunzire kuimba accordion, amafunikira luso lapamwamba. Zoonadi, luso ndi luso ndizothandiza kwambiri, koma chofunika kwambiri ndi kufuna kuchita, kukhazikika komanso khama. Mosiyana ndi maonekedwe, bass sizovuta kudziwa. Ndi dongosolo lokhazikika, lobwerezabwereza la mabatani. M'malo mwake, mumangofunika kudziwa mtunda pakati pa mabasi oyambira, mwachitsanzo, X kuchokera ku dongosolo lachiwiri, ndi mabasi oyambira Y komanso kuchokera ku dongosolo lachiwiri, koma pansi pamzere umodzi. Dongosolo lonse lakhazikitsidwa pa zomwe zimatchedwa bwalo lachisanu.
Mfundo yotereyi ndiyo maziko a bass C, omwe ali pamzere wachiwiri kwambiri kapena pang'ono pakati pa mabasi athu. Tisanayambe kufotokoza komwe mabasi ali, muyenera kudziwa zojambula za dongosolo lonse.
Ndipo kotero, mumzere woyamba tili ndi mabasi othandizira, omwe amatchedwanso magawo atatu, ndipo chifukwa chiyani dzina loterolo lidzafotokozedwanso kwakanthawi. Mu mzere wachiwiri pali mabasi oyambira, ndiye mumzere wachitatu pali zida zazikulu, mu mzere wachinayi zing'onozing'ono zazing'ono, mumzere wachisanu zingwe zisanu ndi ziwiri ndikuchepera mumzere wachisanu ndi chimodzi.
Chifukwa chake tiyeni tibwerere ku ma C bass athu mumzere wachiwiri. Bass iyi ili ndi kabowo kakang'ono chifukwa chake timatha kuyipeza mwachangu. Tadziuza kale kuti bass dongosolo lakhazikitsidwa pa zomwe zimatchedwa bwalo lachisanu, ndipo izi ndichifukwa choti bass iliyonse yokwera poyerekeza ndi ya mzere wapansi ndi nthawi yachisanu choyera. Chachisanu changwiro chili ndi ma semitone 7, ndiko kuti, kuwerengera ndi ma semitones kuchokera ku C kupita mmwamba omwe tili nawo: semitone yoyamba C yakuthwa, yachiwiri semitone D, yachitatu semitone Dis, yachinayi semitone E, yachisanu semitone F, yachisanu ndi chimodzi semitone F yakuthwa. ndi semitone yachisanu ndi chiwiri G. Nayenso, kuchokera ku G semitones asanu ndi awiri kupita ku treble ndi D, kuchokera ku D semitones zisanu ndi ziwiri mmwamba ndi A, ndi zina zotero. chachisanu changwiro. Koma tidadziuza tokha kuti ma C bass athu oyambira ali pamzere wachiwiri kwambiri kapena pang'ono pakati, kotero kuti tidziwe zomwe zili pansi pake tiyenera kuchita chachisanu kutsika kuchokera ku C. H, semitone yotsatira kutsika kuchokera ku H ndi B, kuchokera ku B kutsika ndi semitone A, kuchokera ku semitone yotsika pansi ndi Ace, kuchokera ku Ace semitone pansi ndi G, kuchokera ku G semitone kutsika ndi Ges komanso kuchokera ku Ges mwanjira inanso (F yakuthwa) semitone pansi ndi F. Ndipo tili ndi ma semitoni asanu ndi awiri kutsika kuchokera ku C, zomwe zimatipatsa ife phokoso la F.
Monga mukuonera, kudziwa chiwerengero cha semitones kumatithandiza kuwerengera momasuka kumene mabasi oyambirira ali mumzere wachiwiri. Tinadziuzanso tokha kuti mabasi pamzere woyamba ndi mabasi othandizira omwe amatchedwanso magawo atatu. Dzina mu magawo atatu limachokera ku nthawi yomwe imagawaniza mabasi oyambira mu dongosolo lachiwiri kupita ku mabasi othandizira mu dongosolo loyamba. Uwu ndiye mtunda wa gawo lalikulu lachitatu, kapena ma semitone anayi. Choncho, ngati tidziwa kumene C ali mu mzere wachiwiri, tikhoza kuwerengera mosavuta kuti pafupi ndi mzere woyamba tidzakhala ndi bass E yachitatu, chifukwa chachikulu chachitatu kuchokera ku C chimatipatsa E. Tiyeni tiwerenge mu semitones: semitone yoyamba. kuchokera ku C ndi Cis, yachiwiri ndi D, yachitatu ndi Dis, ndipo yachinayi ndi E. Ndipo kotero tikhoza kuwerengera phokoso lililonse lomwe timadziwa, kotero ngati tidziwa kuti pamwamba pa C mumzere wachiwiri ndi G (tiri ndi mtunda wachisanu), ndiye kuchokera ku G pamzere woyamba woyandikana nawo udzakhala ndi H (mtunda wa gawo lalikulu lachitatu). Mipata pakati pa mabasi pawokha mumzere woyamba idzakhalanso mkati mwachisanu choyera monga momwe ziliri pamzere wachiwiri. Chifukwa chake pali H kupitilira H kupitilira H, ndi zina zotero. Mabasi owonjezera, achitatu a octave amalembedwa powalemba pansi kuti awasiyanitse.
Mzere wachitatu ndi dongosolo la zoimba zazikulu, mwachitsanzo, pansi pa batani limodzi timakhala ndi chord chachikulu. Ndipo kotero, mumzere wachitatu, pafupi ndi maziko oyambira C mumzere wachiwiri, tili ndi choyimba chachikulu C. Mzere wachinayi ndi chojambula chaching'ono, mwachitsanzo pafupi ndi maziko a C mumzere wachiwiri, mu mzere wachinayi padzakhala ac chord chochepa, mu mzere wachisanu tidzakhala ndi chord chachisanu ndi chiwiri, mwachitsanzo C7, ndi mzere wachisanu ndi chimodzi. tidzakhala ndi ma chords ocheperako, mwachitsanzo mu mndandanda wa C adzachepetsedwa c (d). Ndipo motsatira nthawi mzere uliwonse wa mabasi: mzere wa 7. G, mzere wa XNUMX G wamkulu, mzere wa XNUMX G wocheperako, Mzere wachisanu GXNUMX. VI n. g d. Ndipo ili ndilo dongosolo kumbali yonse ya bass.
Zoonadi, zingawoneke zosokoneza komanso zovuta poyamba, koma kwenikweni, pambuyo poyang'anitsitsa chitsanzocho ndipo mutatha kuziphatikiza mofatsa, zonse zimakhala zomveka komanso zomveka.
