What ornament is this? (Haydn Sonata)

[alexf26]

Never seen this symbol in any standard list of ornaments. But it appears quite a few times in my Henle book of Haydn Sonatas
A turn? An inverted turn?
For reference the piece is Sonata (Divertimento) in F Major, Hob. XVI:9: II. Minuet

This pianist plays it like a simple turn:

But I found other recordings that did something else. Check different recordings from great pianists and see if there is anything in common with what they do, if you can't find a source or a preface in your sheet music book that explains it.

Thanks lelle for your reply. I found out in the meantime by more extensive research and asking on other forums that is in fact Haydn's mystery ornament that himself called "half-mordent" and that there is a preface on Wiener text editions that mention it. No one knows in fact what he intended with this symbol but some experts agree that it should be performed as a regular turn in most cases.

Thought I would share and hope it helps other people that may encounter this on Haydn's sonatas urtext editions.

“inverted-turn” or inverted gruppetto in the following sources.

Note that the inverted turn symbol was inconsistent.

Sorry if I’m redundant. This was for myself. I may have to reference this later. The question raised by OP was helpful. Right there with double accidents.

Sorry ego0720 but this symbol does not match the ones on the sources you posted.

This is a more complex question and I would recommend reading the discussion on https://forum.pianoworld.com/ubbthreads.php/topics/3292103/what-ornament-is-this-haydn-sonata.html

Not that is too important for the performance as most people agree to play this as a regular fast turn. It's nice to know though if you would like to learn about the composer's history.

Thanks for the link. OP answered their question that it is half-mordant (sorta). I was learning other things as well and needed to group it here. I am learning so much from everyone. You guys have so much knowledge.
