The minor 7 arpeggio contains the following:
1 – b3 – 5 – b7
It can be thought of as a minor arpeggio, with an added b7. It is a very important tool for any guitarist because it can be used very effectively with a range of minor scales, such as the dorian scale, aeolian scale and minor pentatonic scale.
Links to individual keys will be posted here soon. For now, have a go at memorizing the shapes and changing keys.
