Hello Jacques, Yes, this is possible. It’s just that Lilypond thinks that a slur of that shape would not look good in that place. You can change the scoring parameters Lilypond uses for determining how ugly a slur looks.
For example you can increase Slur.details.edge-attraction-factor to increase the penalty for edge points that are very far away from the anchor points. Note that this results in a rather ugly shape, so you’ll have to tweak other parameters of the slur. I suggest using the height-limit property (determines how high the slur might be), the ratio property (determines how quickly that height is reached) and eccentricity (moves the highest point to left or to the right). I’ve appended an example of values that might look good for your example. Regards, Valentin
