I came across this video when watching some stuff on youtube: https://www.youtube.com/watch?v=KnOES-zVb7U&pp=sAQA
And it was kind of intressting. The standard way of teaching scales on piano is that you start with C-major, then, generally move up with the #-tonalities, following the circle of fifths downwards, and then later the b-tonalities.
But the Chopin way of teaching was to start with the scales: B-major, then Db-major and then F#/Gb- major. Which is very different from the regular way of teaching/learning scales. And the reason for starting with these keys is that they're supposed to be "easier" and maybe more "natural" to play and learn as a beginner. Beacause the short fingers 1 (thumb) and 5 (pinky) are all on white keys and the long fingers 2,3,4 are all on black keys, thus feels very easy and natural. B-major would be the easiest as you start on 1, then Db-major and F#/Gb-major would also be easy but you'd have to start on 2. And I can agree. I learned the normal way with C-major first, and then continuing with #-keys and then b-keys. And I do agree that B-major does feel very natural and easy to play, sort of fits the hand very well. Although I don't find C-major particularly hard. However some scales like Bb-major and ... some others I've had a bit of a hard time with. And some like E-major I find very easy and smooth, like B-major like Chopin teached.
I could see that Chopin's way could be useful, however it has one big downside. Which is music theory. Even though the scales are pretty easy to play, the scales (B-major, Db-major and F#/Gb-major) are the hardest (prehaps) when it comes to theory, having the most flats and sharps. In contrast to C-major which have no flats or sharps. So that's kind of a drawback learning those scales. Which might make it easier learning C-major early on. However it might be usefull teaching those scales and playing a piece in those scales (as a beginner) as they are very plaesant to play in. But reading sheet music in those scales are kind of hard.
So y, it is an intressting idea of starting with those scales. However I personally find the normal way maybe preferable. It is by far easier to read. But y, maybe it can develope a more natural hand position if you practise in the scales chopin teached. Maybe.
So y, an intressting idea, maybe better but I still think the normal way of learning scales is pretty good aswell, and maybe preferable.
