anyone recognize these pieces?

[Rach3]

I've been trying to figure out where these three unrelated quotes come from, they've been annoyingly stuck in my head for a while now (a year), no one i've talked with knows what they are, so anyway....

(first one starts mid-phrase)

1) oboe, slow movement, chamber-music-like, maybe beethoven; 3/4
E G# A  882
AC#D   16 16 8 (or 32s?)
C#BA    //
GAB      //
AGF#     //

2) unsure about the key, orchestral strings ff
D A  AB  A      4 8.16 4 4
(I)    (V) (I)

G F#  EA (?)   4 8.16 4 ?

3) a quote from the 2nd theme from Archduke I (maybe in 20th century context?)
B B  A G G    F# E E    D ...       84 884 884 8..?

(sorry these are amazingly vague...)

thanks!

edited for wrong notes (many)

Never mind on no. 2, just found it (Mendellsohn).

How do you know the notes without knowing the piece? Did you had a score with no name, or you have perfect pitch?

Sorry, the notes were mostly wrong (I'm not used to writing things out in 'CDEFGAH' notation). I think they're right now.
