Hi Kieren, You can explicitly set an arpeggio's start/end positions by overriding the positions property. The internals reference is a bit misleading, as the standard property descriptions mentions left/right only. For an arpeggio, however, positions holds a pair of lower/upper position values. It is calculated by the ly:arpeggio::calc_positions function, and this function can be used in a custom scheme function just subtracting a given amount from the lower value and adding the same amount to the upper value. A simple example, manipulating the "standard" positions by subtracting/adding correctional values (0 at the lower end, 1 at the upper end, as requested by you): %%% MWE begins \version "2.19.80" #(define (widen-arp grob) (let* ((pos (ly:arpeggio::calc-positions grob)) (lower-corr 0.0) (upper-corr 1.0)) (cons (- (car pos) lower-corr) (+ (cdr pos) upper-corr)))) { \override Arpeggio.positions = #widen-arp <c' e' g'>1\arpeggio } %%% MWE ends HTH, Torsten -- Sent from: http://lilypond.1069038.n5.nabble.com/User-f3.html _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
