By the way, for cello: 1. \open means "open string" 2. \0 (finger zero) sometimes is used as a synonym for open string 3. \flageolet means "touch the string at the flageolet position" - often played with the 3rd finger; in this case, the flageolet mark resides closest to the note head, then the finger number 4. \thumb means "played with the thumb". I suspect that it might be combined with the flageolet sign to distinguish between stopping the string (pressing it against the fingerboard) and touching the string with the thumb at the desired flageolet position (typically one octave above the open string, i.e., at the half string length a.k.a. first thumb position). 4. \harmonic is used for playing artificial harmonics by stopping the string at a given note and touching the remainder of the string to excite the desired harmonic (e.g. a fourth above the stopped note). The harmonic sign can be accompanied by a finger number. I have a strong suspicion that the same applies to other bowed string instruments, but I can't state this with full confidence since I'm only familiar with cello (playing) and violin/viola/double bass from reading their sheet music. > > It seems if we give Fingerings and StringNumbers different > > script-priorities by default, as David suggested, it would render a > > lot of this (buggy) code moot. > > I am not sure this would cure the double-engraver scenario, but it might > make some sense trying to at least make both engravers use the same kind > of tie-breaking in comparable situations. > The main problem I see is that /maybe/ some "articulations" behave differently for different instruments. The most remarkable example being the classical guitar (with p/i/f/a fingering) versus cello. How about creating a system similar to the drumset definition for assigning the proper per instrument priorities to these scripts? Best regards, Olivier
