What is the most efficient way to select element specific to the H1

Let's say I'm stupid, but I really want to know the most efficient way to select this specific element:

<a href="/" title=""><h1>MySite</h1></a>

Code (markup):

Here's what I've got from the internet and it's still not specific to the H1 tag:

a[title] {
    color: red;
}
a[title]:hover {
    color: orange;
    text-decoration: none;
}

Code (markup):

I want this element as a unique one and style it differently.

Thank for your help,
