Re: Newbie problem in my first or second score

[Steve Lane]

Thanks, David and Federico — easy fix! All layout engines have their architectural weak spots, so that 's no surprise I guess.

I guess the rendering of that first sixteenth as a grace note in this piece is somewhat arbitrary anyway, since the first measure is always playes simply as four sixteenths. Doubtless some historical reason.

Thanks again,

Hello all:

So I am trying to lay out the first bars of Mozart's Sonata K 333. The first measure is a partial measure. No matter what I try so far, I'm getting an extra time and key signature in the bass clef, in addition to the bass clef first displaying as treble, then adding a bass clef in:

The code is as follows (I didn't see how to make it tinier):

\version "2.18.2"

\include "english.ly"

keyTime = { \key bf \major \time 4/4 }

upper = \relative c''' {

  \partial 4 \grace g16 f8 ef16 d |

}

lower = {

  \partial 4 r4 |

}

\score {

  \new PianoStaff <<

    \new Staff = "upper" { \clef "treble" \keyTime \upper }

    \new Staff = "lower" { \clef "bass" \keyTime  \lower }

  >>

}

Any help appreciated :-)

Welcome to LilyPond!

Sorry you had to discover so quickly perhaps the most persistent bug in the program.

It's easily fixed, though: add a corresponding grace spacer to the other part at the same point.

\partial 4 \grace s16 r4
