Welcome to my ongoing series on music theory. Last week we covered Major Scales and how they are simply a series of half-steps and whole-steps. This week I will explain Relative Minor Scales – which are a bit more complex than their major scale counterparts.
Minor scales share key signatures with major scales. If you’re not familiar with key signatures that’s ok – I will cover that in a future video. For this lesson, we will use the C major scale which has no sharps or flats and discuss the relative minor. Once you are familiar with major scales, finding the relative minor will be very simple.
So for the C major scale you have the following sequence of notes: C D E F G A B C. So this scale has no sharps or flats and the relative minor scale has no sharps or flats either. So what would be the difference between the two? Well the minor scale actually starts on the 6th note of the major scale (A). So an A natural minor scale has A B C D E F G A.
Now there are a couple of different minor scales. In the harmonic minor scale, the 7th note is raised by a half-step. So in the example of A minor scale, if you were playing an A harmonic minor scale, the seventh note would go from G to G#, or A B C D E F G# A.
Another form of the minor scale is the melodic, which has a raised 6th and 7th. Generally though, this scale only goes up and when it comes down it reverts to the natural minor scale with no altered tones. So for A minor it would be. A B C D E F# G# A And descending: A G F E D C B A.
Something you might notice is that if you take a melodic minor scale and raise the third note, it would actually become the a major scale! (This is the parallel minor since you are starting on the same note, not a 6th away as in the relative minor.)
This is pretty much everything you would need to know about minor scales. Please keep watching these videos as we will be covering other scales and modes used from music from antiquity through jazz.
