few lily/notation/orchestration questions

[M.v.Strien]

Hi list,

questions!

- how to notate a halfnote-thrill and wholenote-thrill in lilypond?
- how many strings can a harpist pluck with 1 hand?
- what's the correct way to visually pair e.g. the 1st and 2nd violins in 
an orchestral score? Using { or using [  ? I've seen both types being used 
everywhere.
- what's officially the lowest note of a 5-string double bass? B0 or C1 ? I 
tend to think it's a matter of tuning the lowest string. Following the 
generic tuning intervals, B0 would be the most logical one, but often 
enough I see books stating C1 being the lowest.
