New issue 3928 by address@hidden: Add parameters to articulate/ly to set
the appropriate style for trills and pralls depending on the type
http://code.google.com/p/lilypond/issues/detail?id=3928
The file articulate.ly writes ornaments as used before c. 1800, it seems:
initially, the PrallTriller was four notes beginning with upper auxiliary,
which is what this file writes for \prall but used only in special
positions, cf. example below from "Harvard concise", "inverted mordent",
but it was replaced by the variation in the example below, called the
Schneller. Also, the \trill it writes starts on the upper auxiliary, an
older convention, and slows down with longer value of the note (instead of
being on the 32nds).

There might be needed a series of parameters, setting the style for each
ornament:
The interpretation of these ornamental signs have changed historically. For
example, the Baroque trill starts on the upper auxiliary, whereas in modern
use, after ca 1800, it starts on the main note. And I write them so they
expand into 32nds, but it could also means just a fast alteration. A
composer might write a series of horizontal bars between the two notes to
indicate how fast, or add a few more to indicate as fast as possible.
