Re: 17th century English kbd ornaments

[Pierre Perol-Schneider]

Hi Andrew,

Interesting question.

I'm not familiar with Purcell's work but what I found on IMSLP was that this shake is used as (e.g.) a trill.

So how about :

\version "2.19.45"

purcell-shake-glyph =
\markup\stencil
  #(make-path-stencil
     '(M -0.20  0.05 L  1.55  0.51 M -0.31  0.43 L  1.45  0.90)
     0.17 1 1 #f)
    
shake =
#(define-event-function () ()
   #{
     -\tweak stencil #(lambda (grob)(grob-interpret-markup grob purcell-shake-glyph))
     \trill #})

%% Test:
{
  a'\shake
}

Cheers,

Pierre

Hi Pierre,

Wouldn’t it be better to do these are actual ornaments instead of just markup? I say this because there is a page on the lilyond blog regarding this, but it is only partially complete. If we did them as ornaments the possibility would arise of being able to use them to set English Virginal Music which uses the slash and double slash, through the stem, extensively - although as folks have noted, nobody really knows what they mean.

Since I am a harpsichord player I am one day going to do all the many varieties of the French keyboard ornaments, a rich and flowering garden, so I  have just now taken an interest in this thread.
