Play more sounds at the same time c#

Question

I'm creating a virtual piano keyboard using c#, but I have a big problem with the sounds.

For each key I press on the pc's keyboard, this is the code:

private void Form1_KeyDown(object sender, KeyPressEventArgs e)
{
    [...]   // Other code
    animation(key, name);
}

private void animation(object sender, string name)
{
    [...]   // Other code
    play(keyName);
}

private void play(string keyName)
{
    [...]   // Other code
    string path = Application.StartupPath + "\\sounds\\" + keyName + ".wav";
    var sound = new System.Media.SoundPlayer(path);

    sound.Play();
}

The problem is that with this code I can just press one key (so also just one sound) and this is not realistic. How can I solve this problem? Maybe using threads? How?

Thank'you so much!
