Start from any tonic, using C minor, and play scale degree one, two, minor three, four, five, natural six, flat seven and then of course the tonic again. In C minor, the note names for these scale degrees would be, respectively, C, D, E flat, F, G, A, B flat and, again, C.
Try out different variations of melodies on this scale. For instance, play the notes C, E flat, G and then A, in that order, and notice the striking sound you get with the minor third and the natural six. Create many variations of this; you will see that with different types of rhythms, there are limitless melodies or solos that you can create.
Put on a jam track that lies in the minor mode, or listen to the radio and find a minor mode song, but also make sure you can hear the natural six in the song instead of the flat six. Play this scale in whatever way you want over your chosen song and notice its moody sound.
