Natural scale- isn't it just a major scale starting on a different note? So why not just practice major scales and pretend?
Harmonic. Wtx? (X =f) Let's do a scale then hit pubity just before the last note.
Then there is melodic. Can't make up my mind. Am I raised or not?
(I have to admit the I enjoy listening to the melodic minor scale the most so that's what I like to practice).
if I had to choose one over the other, which should it be? Or do I rotate them all?
Yes I have a great teacher. Yes she gives me instruction on what to practice. Yes I like to be as painful as possible and argue each instruction. I'm old and have earnt the right to be this way. This is where you can help... (Btw i buy her a nice present every lesson anniversary as an apology for the up and coming year)
