What tune is this? Piano, melancholy

[Kalim8]

Hello, I have a small section of a tune in my head, not sure if it even starts in A:
A A# A(long) G A G C G B G B (long)

Please help me find it - I tried playing it to "what's that tune" but didn't get a match.

TIA

I can’t read music or have any idea what that would sound like so I’ll go with a random guess of Fur Elise.

I'm going to guess moonlight sonata

Clair de Lune?

Are you sure about the notes? The last 3 don't fit.

Also, I'd venture the 2nd note is Bb and not A# (yes, it matters )

It's not Für Elise.

Is it definitely a b natural? That's throwing it a bit for me.
Is the C at the upper end of the range or lower

How dod you hear it in your head? Solo piano or with orchestra? (Working on Rachmaninov theory...)

I think it must be clair de lune (hadn't remembered it very well!) thank you @blinkyblonkyblimey and everyone for replying

Can you draw that as music and take a pic ? Or sing it ?
Melancholy piano makes me think Chopin, but I am trying to sing what you have written and can’t work it out.

Satie?
