Interesting notation in Henle

[OCTO]

This question comes from a different forum and is quite challenging. The issue is the meaning of the lines in Henle's edition of Bach Henle BWV817. What do you think?

It is a kind of appogiatura. Usually found in arpeggios, says Clive Brown is "Classical ... performance practice".

[OCTO]

Ok. I have never heard about it! How do you perform the second measure, second beat, RH?

[John Ruggero]

I think that I would play this one as a very fast roll starting on the second beat:

These acciaccaturas are found in one of the several different original sources of Bach's French Suites. The six so-called French Suites are possibly the single most difficult item in the entire classical canon for an editor because of the complexity of the source material.

Hm, but why is that not notated as the LH in the first measure? Is there any manual of that symbols already?

[MalteM]

The left hand in the first measure has a normal arpeggio: every played note (e, g♯, b) is held. The right hand has an arpeggio e–f♯–g♯ but only the e and g♯ are held.

[John Ruggero]

And thus with the roll in the RH of m. 2 only the chord tones are held, as shown in the example above. The acciaccaturas are released as soon as they are played.

Many of these ornaments are not widely known because they are exclusive to Baroque keyboard music.

Thank you, everyone!

I am not well-versed in Baroque performance practices, and I learned something new today.

Precisely. I can add its name is “tierce coulée en ascendant”. A French name because it is mainly used by Couperin and other French composers. In English it’s something like “upgoing third with a passing note” (the normal tierce coulée is descending and more often than not is not explictly noted).

Gasparini calls them “acciaccatura”, indeed, altough his acciaccaturas are often chromatic and are not necessarily found in thirds.

According to my Italian dictionary 'acciaccatura' may mean 'bruise', so maybe you should use them with some caution.
