Kuchepetsa Nthawi - intervals, to-rye pa chromatic. semitone ndi yaying'ono kuposa ma semitone ang'onoang'ono ndi oyera a dzina lomwelo. Mu diatonic Dongosolo lili ndi nthawi imodzi yochepetsedwa - yachisanu yochepetsedwa (tritone) pa digiri ya VII ya zazikulu zachilengedwe kapena II digiri ya zazing'ono zachilengedwe. Mu harmonic. zazikulu ndi zazing'ono zilinso ndi chachisanu ndi chiwiri chocheperako (pa digiri ya 4). U. ndi. amapangidwanso kuchokera kuchepa kwa chromatic. nsonga za semitone za kagawo kakang'ono kapena koyera kapena kuchokera pakuwonjezeka kwa chromatic. semitone maziko ake. Pankhaniyi, mtengo wamtundu wa nthawiyo umasintha, pomwe kuchuluka kwa masitepe omwe akuphatikizidwamo ndipo, motero, dzina lake limakhalabe lofanana. Mwachitsanzo, e - c (ma toni 3) yaying'ono yachisanu ndi chimodzi imasanduka e - ces kapena eis - c (matani XNUMX ½), eharmonically yofanana ndi gawo limodzi mwachisanu. Potembenuza nthawi yochepetsedwa, nthawi yowonjezera imapangidwa, mwachitsanzo. chachitatu chochepa chimasandulika kukhala chachisanu ndi chimodzi chowonjezereka. Mofanana ndi magawo osavuta, maulendo apawiri amathanso kuchepetsedwa.

Ndi kuchepa munthawi yomweyo pamwamba komanso kuwonjezeka kwapakati pa nthawiyi ndi chromatic. semitone imapangidwa kawiri nthawi yochepetsedwa. Mwachitsanzo, chaching'ono chachisanu ndi chiwiri c - b (matani 5) chimasandulika kukhala cis yachisanu ndi chiwiri yochepetsedwa - heses (ma toni 4), eharmonically yofanana ndi yachisanu ndi chimodzi. Nthawi yochepetsedwa kawiri imathanso kupangidwa potsitsa pamwamba pa kapitawo kapena kukweza maziko ake ndi chromatic. kamvekedwe. Mwachitsanzo, gawo limodzi mwa magawo asanu a c – g (matani 3 ½) amasandulika kuchepetsedwa kawiri pachisanu c - geses kapena cisis - g (matani 2 ½), omwe ali ofanana ndi matani anayi.
