Ukuguqulwa kwesikhawu |

Ukuguqulwa kwesikhawu - ukuhambisa imisindo yesikhawu nge-octave, lapho isisekelo sayo siba umsindo ongaphezulu, futhi phezulu kuba ngezansi. Ukuguqulwa kwezikhawu ezilula (ngaphakathi kwe-octave) kwenziwa ngezindlela ezimbili: ngokuhambisa isisekelo sesikhawu siye phezulu ku-octave noma i-vertex yehle nge-octave. Ngenxa yalokhu, kuvela isikhawu esisha, esinezela esokuqala ku-octave, ngokwesibonelo, okwesikhombisa kwakhiwa kusukela ekuguqulweni kwesekhondi, okwesithupha kusukela ekuguquleni okwesithathu, njll. Zonke izikhawu ezihlanzekile ziphenduka zibe ezihlanzekile, encane ibe enkulu, enkulu ibe yincane, ikhule ibe yenciphile futhi ngokuphambene, ikhule ngokuphindwe kabili ibe yehle kabili futhi ngokuphambene. Ukuguqulwa kwezikhawu ezilula zibe izikhawu ezihlanganisiwe nezihlanganisiwe zibe ezilula kwenziwa ngezindlela ezintathu: ngokuhambisa umsindo ophansi wesikhawu unyuse ama-octave amabili noma umsindo ongaphezulu ama-octave amabili phansi, noma yomibili imisindo nge-octave eyodwa ibheke ngakolunye uhlangothi.

Kungenzeka futhi ukuguqula izikhawu ezihlanganisiwe zibe izikhawu ezihlanganisiwe; kulezi zimo, ukunyakaza komsindo owodwa kwenziwa ngama-octave amathathu, futhi yomibili imisindo - ngama-octave amabili ngokuphambene (crosswise). Bona isikhawu.
