So I want to play a fugue

[benedict]

I would like to play the fugue in F of the first book of the Well Tempered Clavier.

Is there a best way to proceed :

-voices separately ?
-hands separately ?
-hands together directly ?
-study the harmony first ?

Should sightreading mastered before playing by memory ?

Is there a Tao of Bach ?

Please tell me how you do when you begin a piece you really want to play for your own joy and not for performance.
