I am currently learning the Fugue of Bach's "Toccata in E-minor BWV914". My question is if I should play the first bar with the 5th finger or not. Meaning starting with "545 3423 1". I feel more relaxed when I start the subject with "434 2423 1", but perhaps it is better to play it with the 5th finger, since maybe later I have no other choice. Obviously I also want to play it at speed and not slowly, so what do you suggest?
I know that the 5th finger fingering will get easier over time, but the question is not about the bar itself but rather if I could play the whole piece with this fingering or if it would be exhausting. Thank you for your answers.
