no thumbs on black notes

[geze]

Anyone been taught that rule? Anyone been  taught that it is
rubbish? Yes I know you cannot play f# major arppegio without putting your thumb on a black note. Views? Comments?

I was taught to avoid it but I learned to do it anyway and do it regularly.

There are old rules, only good to forget 
For example, when I play scales, to warm my hands, I play all them not only with the traditional fingering but also 12312341....  what is a splendid exercise and prepare us for a lot of modern piano compositions. The same with harps.

There was a time when the rule was no thumbs at all - white or black keys.   J.S. Bach started to change conceptions when he wrote music that would be practically impossible to play without the use of thumbs. 

It is really up to the music in question.  Use fingering that allows you to facilitate the passage in the best manner possible.  If that means thumbs on black keys, so be it.  It is probably best not to let old adages get in the way of thinking.

I had never been taught that rule. Seems strange, as there are many times when the thumb on a black key is appropriate.

I've never been taught that. But my teacher have told me that it's not the most comfortable, so it may be useful to not always have the thumbs on black keys ^^

I think the "rule" is mostly for scales. It's common sense, when playing passages that mix black and white keys, to prefer the long fingers (2-3-4) for black keys.
