可能你記錯左啦... 大調既定律係全全半全全全半呀...
所有大調都會以呢個模式存在,所以問E major有D乜flat/shape,我地就咁睇:
全: E去F,半度咋喎,唔夠,所以F要shape.
全: F#去G,又係得半度,唔夠,所以G都要shape.
半: G#去A,半度,岩晒,所以去A就岩.
全: A去B,一度,又岩,唔駛做.
全: B去C,得半度,唔夠,C要shape.
全: C#去D,得半度,唔夠,D都要shape.
半: D#返去E,半度,岩晒.
所以一條E major scale, C, D, F, G要shape.
而minor,有分natural minor, harmonic minor同malodic minor.
Natural minor最簡單. 所有minor都有個relative major,將個relative major既第6個音做開始,就係個natural minor. 例如C major第6粒音係A,所以A natural minor就係: ABCDEFGA,而佢地既音程就係全半全全半全全.
呢個就係natural minor既基本模式. 不過由於由第7粒音leading note返去tonic,樂理家認為個音程係半音既話好聽D,所以會將第7粒音加shape,令leading note to tonic時係返半度. 呢個就係harmonic minor. 以A harmonic minor為例,就變左咁:
A B C D E F G# A
不過如果係咁,第6同第7粒音差左1.5度又太遠,有作曲家覺得難聽,所以連帶埋第6粒音都要shape埋. 呢個考慮,出於leading note to tonic時要半音,係和聲學上既考慮,由tonic落返leading note就唔駛理係咪半音,咁樣出黎既一條scale,叫做malodic minor. 以A malodic minor為例,就會變成咁:
A B C D E F# G# A G F E D C B A
大致上,minor scale就係咁啦,我自己既做法,都係搵左relative major先,然後再微調佢變做malodic/harmonic minor... Say如果要搵F malodic minor,我就會睇左Ab major先,即係Ab Bb C Db Eb F G Ab,跟住變左做
F G Ab Bb C Db Eb F Eb Db C Bb Ab G F
再在上去時第6,7粒音升半度,即係咁:
F G Ab Bb C D E F Eb Db C Bb Ab G F
搞掂.
