[smufl-discuss] Re: "Delayed turn"?

[Stephen Begley]

Hi,

 

I know this as an unaccented turn and they don’t always have a slur in the text but in practice they are commonly executed legato.   The accented turn (over the note on the beat) is normally quite even in execution whereas the delayed or unaccented turn prolongs the first note (upper auxiliary) and the remaining notes are executed as fast as the context will allow.   This prolongation of the first note distinguishes it from the trill.   As CPE Bach remarked, they are found in fast and slow movements.   In regard to the symbol and notation, the only difference is one of placement – whether the notes are close together or not, the unaccented turn is usually centred between two notes.   CPE described it ‘…just to the right of the [main] note’.   Otherwise, the symbol is identical in both cases.   There may be a case for a discrete codepoint for this type of separately placed ornament however, imagine an application that can read and interpret the ornament intelligently not just with regard the duration of each of the component notes, but also any chromatic inflections as the second of your examples illustrates.   Perhaps this is something that should be handled natively in its entirety by the application.   Slurs are typically native to the application and for every house or library style you could have a different slur.  Or not.

A delayed turn is created by placing the turn under a slur, centered between two notes that help interpret the turn. It can include the vertically aligned accidental a, but all under the slur. See attached for two examples. No reason I can see to have it be part of SMuFL since depends on a variable-length slur. Whenever I've seen it, though, the two notes are usually not all that far apart from each other, but still I don't see a fixed size glyph being used.

MusicXML defines an ornament called a "delayed turn."  What is this
visually?  I don't see any such symbol in SMuFL.
