Text above a notehead or rest regardless of collisions with staff

[Paolo Prete]

Hello, 

is it possible to place "some text" above a notehead (or a rest) regardless of collisions with the staff? Maybe a start could be to use the Fingering object, but I don't know how to change "1" to "some text"

{
\override Fingering.staff-padding = #'()
\stemDown
c'-1
}

Thanks!

Best,

P
