I'm looking to see if anyone here know the name of a piece of classical music I'm thinking of. I can't seem to find it myself, so here it goes.
It's a pipe organ piece that's played around Easter. (I'm not sure, however, if it has anything to do with Easter, or even if it must be played on an organ.)
It's melody is goes kind of up and down up and down, over and over. (That's really the best I can describe it with text.) I'm pretty sure it has a main body, but I it's melody is all I can remember.

Does anyone have any idea what the name of such this piece is?
Sorry if this is too weird,
