I'm writing a musicology paper and need some roman/schenkerian analysis tools. Notice the image, the "roof" over the numbers? How to produce this?
You get such a “roof” with \hat:
$\sharp\hat{4}$
There's also \widehat for – well – wider objects:
$\widehat{11}$
Both are mathaccents and therefore need to be used in math mode.
