Artur Schnabel: C major scale

C major scale on the piano, which is adhered to with greatest reverance - uses the RH thumb, the strongest finger, on the subdominant, with the LH on the dominant. This RH movement, 3-4-3, is certainly ingenious. But musical only for the LH; musical by accident. As it is built the LH start with the 5th finger, which in the case of C major scale is a 'priority'. The RH should compensate its disadvantage with only 4 fingers, thumb on 'G'. If played as ordered, RH alone - or worse, in unison with LH, the subdominant, touched with the strongest finger, might easily get a musically unintended accent on it, and thus lead to a crime against the harmonic system of centuries and make music the victim of standardization. Not ingenious, but just silly, is the order never to use your thumb on a black key. Why not, if the position of the hand makes it by far the best fingering?
