Dhexdhexaadyada La dhimay - dura, si-hing on chromatic. semitone waa ka yar yahay semitones yar oo saafi ah oo isku magac ah. Diatonic Nidaamku waxa uu ka kooban yahay hal barood oo la dhimay - shanaad oo la dhimay (tritone) oo ah heerka VII ee weyn ee dabiiciga ah ama heerka II ee da'da yar ee dabiiciga ah. In harmonic. kuwa weyn iyo kuwa yarba waxay ka kooban yihiin toddobaad la dhimay (shahaada 4aad). U. iyo. ayaa sidoo kale laga sameeyay hoos u dhaca chromatic. Semitone ugu sarreeya ee dhexda yar ama saafiga ah ama korodhka chromatic. semitone ee salkeeda. Xaaladdan oo kale, qiimaha codka ee muddada u dhaxaysa ayaa isbeddelaya, halka tirada tillaabooyinka ku jira iyo, si waafaqsan, magaceedu waa isku mid. Tusaale ahaan, lix meelood oo yar e - c (3 tones) waxay isu beddeshaa la dhimay lixaad e - ces ama eis - c (XNUMX ½ tones), oo la mid ah shan meelood oo nadiif ah. Marka dib loo noqdo dhexda la dhimay, dhexda korodhay ayaa la sameeyaa, tusaale ahaan. Saddexaad oo yaraaday waxay isu beddeshaa lixaad la kordhiyey. Sida dhexda fudud, dhexda isku dhafan ayaa sidoo kale la dhimi karaa.

Iyada oo hoos u dhac isku mar ah ee sare iyo korodhka saldhigga u dhexeeya chromatic. semitone waxa la sameeyaa laba jeer inta u dhexaysa la dhimay. Tusaale ahaan, ka yar toddobaad c – b (5 tone) waxa uu isu beddelaa laba jeer oo la dhimay cis toddobaad cis - heses (4 tones), oo la mid ah lix meelood oo yar. Muddada labanlaabantay ayaa sidoo kale la samayn karaa iyadoo hoos loo dhigayo meesha ugu sarreysa inta u dhaxaysa ama kor loo qaado salkeeda iyadoo la isticmaalayo chromatic. cod. Tusaale ahaan, shanaad ee saafiga ah c – g (3 ½ tone) waxa ay isu beddeshaa laba jeer oo la dhimay shanaad c – geses ama cisis – g (2 ½ tones), kaas oo si fiican u dhigma afraad saafi ah. Marka dib loo celiyo dhexda laba jeer hoos u dhacday, laba jeer oo kordhay ayaa la sameeyaa.
