Dear list,

how can I adjust the bracket span length and 8va sign placement (horizontally) on a case by case basis?

I found the ottava bracket interface section in the manual but am not sure how to implement it:

Many thanks,

Here's my quick little function for moving the endpoints of 8va brackets horizontally using shorten-pair and extra-offset.  It's not ideal because extra-offset doesn't affect spacing.

%% stretch an ottava bracket

\version "2.14.1" 
stretchOttava = #(define-music-function (parser location offset) (pair?)
        #{
         \once \override Staff.OttavaBracket #'extra-offset = #(cons (- (car $offset)) 0)
         \once \override Staff.OttavaBracket #'shorten-pair = #(cons 0 (- (+ (car $offset) (cdr $offset))))
         #})

\relative c' { \stretchOttava #'(-2 . 5) \ottava #1 c'' c \ottava #0 c c }
