写音乐最迷人的地方是有无穷尽的可能性写出带有各种情感色彩的曲子, 方法也简单,懂简单乐理就可以在钢琴上实践,12个major scales, 12 minor (harmonic minor 古典音乐用的), 每个scale都有它的 primary chords (1, 4, 5) , secondary chords (2, 3 6, 7) ,选一个 major or minor scale, 按节奏来弹 chord progression, 已经是弹伴奏的曲子了,右手弹scale中选出的notes( 旋律melody),开始可以随机选配 chord progression (左或右手)) 这种组合就是完整的曲子。
弹琴快乐的地方是自己随机实践chords/scale时, 不断发现作曲家们写出的熟悉的调子,啊哈的时刻有快感, 原来不小心也能写出那些名曲的一小节呢。 昨天发现了一个,记录一下。G Ab Bb - Eb , going down to middle c , d ,Eb - Bb (Bb before middle c) , 意外发现rachmaninoff 名曲的一个motif !
今天在尝试这两个有趣的chord progression ,记一下,以前用笔记本记录有趣的chords pattern,常不知那笔记本夹在哪堆书里,以后搬博客里
1) c minor scale : 1 3 6 7 , scale keys : c d Eb f g Ab Bb
C minor chord (1) -- c Eb G
Ab major chord (3 ) ab c Eb
eb major chord (6 ) -- Eb G Bb
Bb major chord (7 ) -- Bb d F
chords 可以被inverted, 这样指法变换容易,不用跳来跳去的减少手指跳跃难度 , , 比如 c to Bb离的很近,上面的组合可以改成以下
c Eb G
c Eb Ab
Bb Eb G
Bb D F
2) chord progression (F major scale) 4-5-1, scale keys : f g A Bb c d e
Bb maj chord (4-5-1 )
C majr chord
F majr chord
几种有趣的练习方式可以帮助写曲,练chords和scales,也不会枯燥 (ways to practice and experiement )
1) LH : root note for each chord , RH : arpeggio for above chords
或反过来
2) LH : chord progression , RH : limit to single or 2-3 notes
或反过来
3) LH : chords (or just play 1st and 5th) , scale notes (ie , c minor scale , 1st scale node could match with 1st note of chord , ie , Ab c eb , scale note stars with Ab )
4) LH: root note ( c, c ) , RH: chords
附几张图 primary chords (1 4 5) and secondary chords (其他),如果24 scales熟悉后这些就不难记了, first two prim chords for major/minor scales , last two secondary chords major/minor scales.
