Soon I hope to perform this short piece. What are your thoughts on it?
I've noticed that whatever the R. H. plays, the left hand generally
plays a measure later. At first, I thought it would be easy, but it's always easier to hear a piece than to play it.
This is one of the best known of the inventions. This is one of those pieces that every pianist should have in his/her repertoire. Besides, you can never go wrong learning any of Bach's music.
The mimicry between the hands is due to the fact that this invention is essentially a canon. It is not a strict canon in that there are moments here and there where the imitation does not occur, but as in all music creation, the "rules" go out the window the moment that a composer has a more musical idea.
This one can be a bit of a finger twister at times. One thing that can cause a little confusion in learning this one is switching from the hands doing two different things (one with 8th notes going in one direction versus the other with 16ths going in the opposite direction) to the both playing the same pattern. Begin slow but be sure to keep a steady pace. Then you can build up speed. In the end this one does need to dance.
