It’s often hard to know if a tune, or a section of a tune, is in a minor key. I’d say your first point of call is to check if there’s a dominant chord that can be seen as the V7 chord to the minor key you expect it to be. If so, chances are it’s in a minor key. But what should you actually do here? There are lots of answers to that, but if you’re new to this, a simple approach is to play the harmonic minor scale of that key. For instance, in this video I’m talking about a moment in Avalon where we see a D7 going to a G minor chord. This tells me it’s time for the G harmonic minor scale. The G harmonic minor scale is one of the only places where both chords, D7 and G minor, can be found. It’s really that simple. Can any of you theory heads tell me what other scale contains both of these chords? Right now my coaching package (4 lessons, practise plan and everything else on here) and my VIP subscription (Jazz Violin Practise Club and all the material) is at a super low price, about to change on the 1st of December. If you are interested in getting simple help with your playing, now is the time to get in.
