Hi Ben
Maybe I am heading down a rabbit hole with this one, and my ultimate objective is pointless, as in reality, like you say, if we're fortunate to have 5 rows at our disposal, so long as we can start on an appropriate finger, we can use the same fingering all the time.
However, I remember my CBA teacher from all those years ago, who was also a performer, initially restricting me to using the first 3 rows, so I could use the fingering learnt in the scales. It was only later that he permitted me to utilise the additional rows to establish if there was an easier path to take.
Furthermore, not everyone on this forum may be fortunate enough to have 5 rows to their disposal, and for them, alternative fingering my be beneficial.
I've enjoyed learning scales using your fingering, as it rotates the hand in the opposite direction (down) to the fingering I've been using, potentially giving me another option when learning a new piece, but if I was to embark on documenting fingering for 4 or 5 rows, it would never be completed, as there are so many permutations.
I consider melodic minor different to you, where only the 3rd is diminished going up, with the addition of the 6th and 7th being diminished coming down. This is also how they are shown in the Anzaghi tutor.
It not clear to me if the your major scale fingering is restricted to 3 rows, as the penultimate note (i.e. 7th), which is in row 3, is shown as played by your 3rd finger, whereas the other row 3 notes (i.e. 2nd and 4th) are played by your 2nd finger, which would be my logical choice also for the 7th?
For my own reference, I've drawn up all the scales using the 2 methods (i.e. primary fingers 1-3, and 2-4), which utilise the hand rotated in the both directions, and included snippets below. But in view of what you're said, I'm not sure if I should take it any further in this topic if it's going to confuse matters.
Thanks
Brian
