Emculweni, i-octave (: yesishiyagalombili) noma i-octave ephelele yi- isikhathi phakathi kwephimbo lomculo elilodwa nelinye elinengxenye noma kabili imvamisa yalo.
Ichazwa yi-ANSI njengeyunithi yeleveli yefrikhwensi lapho isisekelo se-logarithm sikabili.
Ubudlelwane be-octave yinto engokwemvelo eye yabizwa ngokuthi "isimangaliso esiyisisekelo somculo", ukusetshenziswa kwayo "okujwayelekile ezinhlelweni eziningi zomculo".
Izikali zomculo ezibaluleke kakhulu zivame ukubhalwa kusetshenziswa amanothi ayisishiyagalombili, kanti isikhawu phakathi kwamanothi okuqala nawokugcina yi-octave.
Isibonelo, i-C Major isikali ngokuvamile ibhalwa i-CDEFGABC, i-C yokuqala neyokugcina iyi-octave ngokuhlukana. Amanothi amabili ahlukaniswe i-octave anegama lohlamvu olufanayo futhi ekilasi lephimbo elifanayo.
Izibonelo ezintathu ezivame ukucashunwa zemiculo equkethe i-octave enhle njengesikhawu sazo sokuvula ithi “Singin' in the Rain”, “Somewhere Over the Rainbow”, kanye “Stranger on the Shore”.
Isikhawu phakathi kwe-harmonics yokuqala neyesibili yochungechunge lwe-harmonic i-octave. I-octave ngezinye izikhathi ibizwa ngokuthi i-diapason.
Ukuze ugcizelele ukuthi ingesinye sezikhawu eziphelele (okuhlanganisa ukuhlanganisa, okwesine okuphelele, kanye nesihlanu esiphelele), i-octave iqokwe njengo-P8.
I-octave ngenhla noma ngezansi kwenothi elikhonjisiwe ngezinye izikhathi lifushaniswa 8va (= Italian all'ottava), 8va bassa (= Italian all'ottava bassa, ngezinye izikhathi futhi 8vb), noma umane u-8 we-octave ohlangothini olukhonjiswe ngokubeka lolu phawu ngenhla. noma ngaphansi kwabasebenzi.
NginguJoost Nusselder, umsunguli we-Neaera kanye nomkhangisi wokuqukethwe, ubaba, futhi ngiyathanda ukuzama izinto ezintsha ngesiginci enhliziyweni yesifiso sami, futhi kanye nethimba lami, bengilokhu ngidala izindatshana zebhulogi ezijulile kusukela ngo-2020. ukusiza abafundi abathembekile ngokurekhoda namathiphu esiginci.
