RE: Consecutive trills

[Mark Stephen Mrotek]

Hans, 

Without getting into detail, Arnold Dolmetsch contends that
"They (the various indications of a trillo) have no particular shade of 
meaning, being only the consequence of his (Bach's) lack of system."
The Interpretation of the Music of the 17th and 18th Centuries, p. 169.

In BWV 1067, first movement, there is for the flute a long note with several 
ties with a trill span ending somewhere in the middle, indicating the length of 
the trill followed by untrilled part. I do not know if Bach himself write it 
that way, but I found it useful in Balkan music, where it is common to not have 
an alteration on the last 16th of say a trilled dotted 8th note. I decided to 
write that with an 8th having a "tr" tied to a following 16th, otherwise those 
not accustomed with the style would not know how to play it (and I find it is 
hard to remember). Trilled notes can be syncopated in Balkan music, and then it 
may be necessary to use a trill span. Hindemith, "Elementary Training", says 
that on short notes, a trill can have only one alteration. This occurs in 
Balkan music, but I decided to write a prall sign as it is more compact.
