配chord 一問 10point

minor key分為natural minor, harmonic minor 同melodic minor三種。
點知一首歌係邊種minor，就要睇佢o既sol-fa音。
如果s音變成se，f音無變o既，呢種就係harmonic minor。
如果s音變成se，f音變成fe，呢種就係melodic minor。
但係如果成首歌s同f都冇變，呢種就係natural minor。

以下係3種minor key o既chord。

natural minor
1 chord: minor
2 chord: diminished
3 chord: major
4 chord: minor
5 chord: minor
6 chord: major
7 chord: major

harmonic minor
1 chord: minor
2 chord: diminished
3 chord: augmented
4 chord: minor
5 chord: major
6 chord: major
7 chord: diminished

melodic minor
1 chord: minor
2 chord: minor
3 chord: augmented
4 chord: major
5 chord: major
6 chord: diminished
7 chord: diminished

如果有人問你Am有咩chord，首先你要知道呢首歌係邊種minor。
eg. 如果首歌係natural minor，A natural minor o既音階係ABCDEFG，
根據上面natural minor chord o既排列，
1 chord係minor 於是變成A minor,
2 chord係diminished於是變成B diminished, 如此類推，
最後變成A minor, B diminished, C major, D minor, E minor, F major, G major

你可以搵返個minor key既"關係大調"(relative major)
例如Am既關係大調就係C
Bm既關係大調就係D
點計呢?好簡單,你要記住個關鍵字,"3個半度"
計一下A向高3個半度既音,A>A#>B>C...
B>C>C#>D....所以minor搵major就係向"高"3個半度
掉轉major搵minor就係向低3個半度

回正題,既然講得上"關係",即係Am=C
所以Am既chord就係C既chord
即係C,Dm,Em,F,G,Am

如果有人問你minor key既chord,你只係識搵返佢個關係大調就知道了
