S3 - Major

1. Open attached score (produced in 1.3).

Result: The lower of the multi-voice notes don't shift.

The numbers represent the pages of 'Behind Bars' featuring these examples.

Page 49 states: "Arrange chords so that notes on the 'correct' side of each stem align vertically: … The only exception is when a tone or semitone separates the two parts. In this case, the lower part is displaced to the right (if the parts are vertically aligned, it is hard to tell which note belongs to which part):"

Thanks for the report. I'll look into how easy it is to detect these cases. Currently, the collision-avoidance code considers only the bottom note of the upstem chord and top note of the downstem.

Meanwhile, I'd love to see some independent corroboration of this bit of advice. It kind of comes off to me as a personal preference on Gould's part. Any other references on the subject anyone can point to, or examples in the literature? FWIW, it seems Finale applies the offset, Sibelius does not.

I'm inclined so far to not apply the offset, and let users who wish to follow Gould's personal advice apply the offset themselves. This also works well with principle that says when in doubt, it's easier to manually offset two things that default to being aligned than it is to manually align things that default to offset (you'd need to know the exact amount of the offset and hope it remains constant from release to release).

But I'll leave this open in case new evidence comes in, also as a reminder of a possible feature to add in the future (an option to control the default).

1) note entry
2) C
3) Shift-D
4) Voice 2
5) B
6) Shift-C
7) Drag one the notes, it causes multiple of these weird configurations
