ottava text and offset

[Paolo Prete]

Hi all,

How can I make the "ottava" text similar to that:

(note the "big fat 8 " and the smaller "va")

In addition, how can I move the ottava text+bracket so that the X position of 
the note head is exactly placed where the number 8 finishes? (note the red 
segment in the above image)


thanks very much,

regards,

Paolo
