Is the note following a tied note usually legato (for that same voice) in bach? this is the F♯ minor prelude from the wtc II BWV 883 for example measure 11 in the bass voice there is an F which is tied across the bar line. Would I slur or play the G which immediately follows as legato and then detach the A and the F which follow in that voice?
