Is she a music fan? Unusually good at pitch, rhythm, instruments, or memory for music and lyrics?

Williams Syndrome is associated with unusual aptitude for music (or perhaps just unusual compared to the other more serious learning difficulties). There are even music-focused summer camps specifically for kids and adults with Williams Syndrome.

Interesting. AFAIK musical ability is somehow linked with mathematical ability, yet Williams Syndrome involves mathematical impairment..?

These aren't necessarily in conflict. Imagine a system,

    x = A + B
    y = A - B

If, typically, we see large ranges of A and small ranges of B, we'd say x and y tend to move together. But that doesn't preclude someone with a highly unusual B.
