音階的四度音練習應用 ( Application of Minor Scale in 4th)

這次Techniques From Songs的主題將以楊丞琳的青春住了誰中的電吉他獨奏討論音階的四度音練習應用。

這是倒數第二小節電吉他獨奏的大致內容：

雖然整首曲子是E大調，但這裡大致上是使用E小調五聲音階來對應G和弦，直到B和弦時才有回到E大調的感覺。

而在這一小節的中，樂句大多以四度音前進，雖然這或許只被當成五聲音階慣用的技巧，但我們可以把這個概念抽出來，應用在完整的小調音階練習上。這樣即是我們以1 - 4、2 - 5、b3 - b6…的四度音程來演奏音階。

若將這個概念套用到整個指型會是這樣：

大家可以試著將這樣的四度音練習套用到不同的指型、把位、調上面，並試著在自己的獨奏上。影片最後有預留一段和最後兩小節類似的Loop，大家試著玩玩看吧！

This time in Techniques From Songs, we are going to talk about the application of Minor Scale in 4th from the solo of this song.

This is the 2nd to the last bar of the solo part.

The whole song is in the key of E, but in here the guitar player use E minor Pentatonic scale to match the G chord. The E major feel doesn't come back until the B chord.

In this measure, the note are basically moving in 4th. although we can deem it a cliche of minor pentatonic scale solo, we can apply the concept into a natural minor scales, like 1-4, 2-4, b3-b6... etc.

So if we put it into a whole pattern, it will be like this:

You can try to apply the scale in 4th concept to different patterns, positions, and keys. Also, use it in your own solo. I will keep a loop that sounds like the last two bars of the solo, try it yourself!
