Thanks. I know the notation and meaning (I have Grove in both html and braille (concise version in braille)), but it seems that Lilypond can't generate it.I still can't figure out what's the difference between mordents and various pralls :-)
my girlfriend, a clarinettist and oboist, comes across these ornamentations far more often than i do. she told me the following:
mordent: single alteration down (c b c) prall: single alteration up (c d c)going by some other references (dolmetsch, kopprasch [iirc]), i think the following is how the other ones are interpreted:
prallprall: double alteration up (c d c d c) prallmordent: up then down (c d c b c) upprall: prall preceded by a lower step (b c d c) downprall: prall preceded by the upper step (d c d c) upmordent: mordent preceded by the lower step (b c b c) downmordent: mordent preceded by the upper step (d c b c) pralldown: prall finishing with the lower step (c d c b) prallup: prall finishing with the upper step (c d c d) lineprall: your guess is as good as minesee the attached lilypond file for a possible interpretation. as with all ornaments, the exact timing is dependent on the period, the performer and which method he used to learn the ornaments from (kopprash for instance suggests a turn be performed as a triplet rather than as straigh 16ths...).
and to all the musicologists: feel free to correct any rubbish i've just posted.
