For what it's worth, when I took music theory, we were advised (and this is in consonance with numerous music copy tutorial books, I can quote references for some if needed) to keep stems in one direction when passing through the middle line of the staff.
Thus, for a scale starting on the bottom line and going to the top, the middle line stem would be up, because the previous notes' stems had been going up. Coming back down, the stem would be down, because previous stems had been down. In this case, Mr. Martelli's case would be satisfied, as well as those cases where c b a calls for the stem reversal at a, not b, and c b a b c has the b with stem down first and then up. raybro Laurent Martelli wrote: > > \relative c'' { c b c } gives stem up, down and up.
