Diatonic scale means that 'the natural scale, consisting of 5 whole tones and two semitones, as it is produced on the white keys of the keyboard.There is of course a corresponding scale in each key.Music is called diatonic if it is confinced to the notes of this scale, to the exclusion of the chromatic of the chromatic tones.
For instance, the C major scale the melodic progression c-d-e- and the chord dac' are diatonic, while c-d #-e and dabc are chromatic.'





Harvard Dictionary of Music

Diatonic scale 即是說某段樂章,
所有屬於某個大調的音。
從以上文章可看出,
如某段樂章是Ab 大調,
Ab大調的diatonic音便只有:
Ab,Bb,C,Db,Eb,F,G,
其他的音便不屬於Diatonic之列了。
diatonic chord,Diatonic scale
即若是在Ab大調中便只用了以上的音來做出
scales and chords.

如某段樂章是G小調,

G小調的diatonic音便只有:

G,A,Bb,C,D,Eb,F#,(harmonic minor)

G,A,Bb,C,D,E,F#,(melodic minor)

其他的音便不屬於Diatonic之列了。

blues是不是Diatonic便要視乎那首歌是用什麼調,
有很多臨時升降號,
較難定出那些音是Diatonic

the C major scale the melodic progression c-d-e- and the chord dac' are diatonic, while c-d #-e and dabc are chromatic.'
因為C major 有cdefgabc'音,所以"dac"是其中的3個音,屬於Diatonic
同"dabc"係 d,a flat,c' 音的意思

2008-04-16 15:04:51 補充:
d,a flat,c' 音不是C major 的Diatonic之列

2008-04-16 15:06:49 補充:
如果係A minor key ,
它的diatonic scale即是A B C D E F G# 這些音
G#=Ab,即是A minor 的diatonic scale.

原則上,合乎那個key 的 scale 音就是diationic

如果A minor key, 如果你玩 A natural minor, A harmonic minor,才是diatonic

唔該哂你既幫助呀!! 你幫我明左好多^^"

但是不太明白你講的
the C major scale the melodic progression c-d-e- and the chord dac' are diatonic, while c-d #-e and dabc are chromatic.'
我想問下"dac"同"dabc"係咩意思

另外diatonic scale
我看過了一些說明,是由2個perfect fifth所組成
如由C開始組成 ,即C D E F G A B,即跟你所講的一樣

2008-04-12 15:11:59 補充:
如果係A minor key ,
diatonic scale即是A B C D E F G 這些音
但是harmonic scale 入面有 Ab,還算是 diatonic???
這點還有點不明白
非常感激你的教導!!!

對不起,先2天比較忙,沒有上這個發問...
非常謝謝你的回答

那麼是不是可以乎合那個key 的就是diationic??

diatonic scale 是 可以乎合那個key 的scale???

如果Am key, 如果我玩 A Dorian,A natural minor, A harmonic minor, A blues 都是diatonic

2008-04-17 15:13:18 補充:
但係diationic scale不是指合乎 全全半全全全半音???

a minor diatonic 的不是A B C D E F G?

harmonic minor scaleA B C D E F#G

它的f音 #了~ 還是diatonic???


還是有點混亂=.=
