When a short appoggiatura is sharped at note G...

[barnowl]

are all G notes in that measure—large and small—also sharped?

I am referring to measure 23 0f K.545, in which the first note, a short appoggiatura, is sharped, then 4 notes later there is a 32nd G that doesn't sound so hot when I play it sharped.

I have a nasty suspicion that sharped is how it should be played.

[pianistimo]

as far as i know, a sharped appoggiatura has nothing to do with affecting the rest of the measure.  good question!  i think it has more to do with the ornamentation of that particular note.  if mozart wants you to play a G# - he'll write it in on the rest of the notes.  mozart is fairly straightforward - unlike barber and some composers like that.

[barnowl]

I didn't mean to sandbag you, Pianistimo, and I should have mentioned this in the OP,
but in very next measure, Mozart naturalizes the first G as you will see (I hope) in the attachment.

[barnowl]

Pay no attention to the mirage. There is really just one attachment, and if you didn't get so drunk last night you would not be seeing double today.

Yep, dead right barnowl. The fact that the accidental occurs on an ornament makes no difference - the remaining notes are still affected.

Your ears are playing tricks. This G is part of a written-out turn; the lower note of a turn usually sounds best if it is a semitone below the melody note. Have a listen to the difference this makes at https://www.geocities.com/paris/3486/moz_545a.mid

Notice the natural sign next to the G in the next bar? This is a 'cautionary' accidental placed there by the editor, in case players forget that the G is no longer sharpened.

I believe you, Steve, even though, for some unknown reason,  I couldn't play the clip. I have better solution anyway.

I can (and, will) play the 1st movement on my digital pianoforte - as slowly as I want and I'll listen for the sharpened g - not just the G# of the appoggiatura but also the big boy note — the G# that follows soon after.

Ta-Daa. 

The clip is the passage played with G#, then G natural, first slowly then up to speed.

The G natural sounds even more naff than I imagined

Ah!  It played this time around, and the light dawned. Thanks, Steve.

By the way, I looked up naff in dictionary.com:

naff1 (nf)  Unstylish, clichéd, or outmoded.

Also...

naff2 (nf)  intr.v. Chiefly British Slang naff·ed, naff·ing, naffs
To fool around or go about: “naffing about in a tutu” (Suzanne Lowry).


Phrasal Verb:
naff off    Used in the imperative as a signal of angry dismissal.

Good word.

In my Henle edition, the 32nd g has a sharp too.

Wolfie, this is the first I've heard of Henle Editions. What is there about them that you and others like? (Not being funny. I'm interested.)

I prefer them as "Urtext" edition for Beethoven, Mozart (though the latter maybe better with "Wiener Urtext"), Brahms and others. Not for Chopin. I'm not very strong into sources research. But these editions give me the feeling to read (hopefully) what the composer has intended to write.

Thanks.
