Where could I download piano and drum sounds for my map?

I’m going to try make drums and piano in a map, but I need sounds of drum set and piano.
Any idea where I could legally get them?

I doubt single note samples will be illegal to download and use on a non-commercial project.

You’re right.

But to the topic, I once saw em on some site, with every note as .wav

I meant every note as .wav or .mp3 or anything.

How could I record them?

It’s really easy to set up.
