Re: Settings for automatic beam slope

[Andrew Bernard]

Hi David,

Thanks. That’s a very illuminating article from Mr Spreadbury.

I gather, then, that beam-quanting is the method used by lilypond to achieve the cardinal rule of Ross:

"The placement of a beam follows the cardinal rule that when it falls within the staff, its ends must either sit [on], hang [from], or straddle a staff line, whether the beam is single or multiple."

This article also, I believe, answers my very question, why my sets of eight sixteenths mostly come out flat beamed.

"The beam is also horizontal if the notes in the group are in a repeated pattern of pitches;…”

These written out early baroque ornaments are obviously the type of repeating group referred to, so it looks like lilypond honours this convention also. The attached code illustrates the flattened beams. It does however raise the question as to why the second group with stems down have a slope, unless my eyes deceive me.

Andrew

I presume this is to do with Ross's Cardinal Rule; have a look at
