harmony chord identification

[quaver]

Measure 2 of the following baffles me.  The second beat of measure 2 with the C# eighth note seems to be hanging by itself. Whatever chord could this be. Could somebody analyze this measure for me.  I think the tied E in the first measure is a suspension.  I'm not sure about the rest of the music yet and whether I can identify the chords so if you find any other 'difficult' harmonies perhaps you would enlighten me.  Many thanks for your time.  It really helps in my endeavour to understand classical progressions.

Oh gosh, I am now already stuck on measure 4 also.  Help!

If you combine the last two eighth beats in measure 2, you get E - F# - C# - A# which is an F#7 (dominant to the B chord in the next measure)

In measure 4 I see nothing tricky, as long as you don't let the suspensions in the top voice fool you.  What beat are you confused on?

[quaver]

Yes, I am ok with beat 4 of measure 2.  It is the second beat of measure 2 that is the question.  The c# in the second beat seems to be 'floating' and belongs to nowhere.

Oops I slipped on a key and my reply was posted somehow.  The rest of my posting was:
In the 4th measure I think I have it now.  It seems that beat 3 of the 4th measure, has a couple of appogiaturas in the soprano, which clarifies things somewhat. Of the four sixteenth(semiquavers) in beat 3(soprano voice) I have D and the second C as appogiaturas.  Would you agree with that.

[ionian_tinnear]

I would call the 3rd beat, without the appogiatura (D), (A - E - C#) and A major triad, and the next C# an appogiatura resolving to an E major triad (G# - B - E)

I had mis-read your question about measure two.  That C# does seem out of play, at least oddly notated.  The harmony there could be an implied A major (E - E - C#) but that one is really tricky!

Thanks for the question!  Has been many years, too many to mention, since the good ol' college days when I had to analyze stuff.  What fun
