Hi,
Another scale that you may want to consider having in your toolbox is the Melodic Minor Scale.
The notes in the C Major Scale - C D E F G A B C (you should know by now :))
The formula for Melodic Minor Scale - 1 2 b3 4 5 6 7 1(8) = C D Eb F G A B C
We can apply this scale on a minor chord but preferably not on a minor 7 chord. Try it on a Minor Maj7 Chord.
You can also apply the C Melodic Minor Scale on the (V7) which is G7 in the key of C
The notes in a G7 = G B D F, which are also inside the C Melodic Minor Scale.
You can try the D Melodic Minor Scale, F Melodic Minor Scale and the Ab Melodic Minor Scale.
Have fun.
