I see that most online scores of Beethoven's "Für Elise" specify its meter as 3/8. However, this one has 3/4 instead, which seems to make it easier to read (all the 1/16th notes become 1/8). I don't see any advantage to using 3/8 there (except maybe showing respect for the author).
What is the purpose of using 3/8 instead of 3/4?
Does 3/8 give any hint on how the author intended it to sound like?
