(2) アベイラブルノートスケールに含まれるペンタトニックスケール

 ここでは、アボイドノートを含まないものに限定して、アベイラブルノートスケールに含まれるペンタトニックスケールを考えていきます。

例えば、C Lydian Scale には、以下のペンタトニックスケールが含まれます。

 C Lydian Scale




 C Major Pentatonic Scale




 C Pentatonic Altered 4th Note




 D Major Pentatonic Scale




 E Pentatonic Altered 3rd and 5th Note




 Gb Pentatonic Altered 2nd and 3rd and 4th and 5th Note




 G Major Pentatonic Scale




 A Pentatonic Altered 3rd Note




 B Pentatonic Altered 2nd and 3rd and 5th Note




 同様にして、アボイドノートを除く各アベイラブルノートスケールに含まれるペンタトニックスケールをまとめると、次のようになります。



 以上がアボイドノートを除くアベイラブルノートスケールから派生するペンタトニックですが、すべてを覚えようとすると必要以上に混乱してしまい、利用価値も低いものもありますので、ここでは、Major Pentatonic および、それからの変化音が比較的少ないものものに絞って練習します。今回取り上げるペンタトニックを、ルートがCのコードでのアベイラブルノートスケールごとに示します。なお、()内は、元のスケールから見た度数です。これにより、ペンタトニックを用いたフレーズがコード上でどのようなサウンドになるかがわかります。
