lyrics font size

[vwf]

Hello,

I try to set the font-size of lyrics, but this seems less straight
forward than I expected. So far, the notehead size changes with the
text-size. How can I set the size of the staves and the lyrics
independently?


This is what I made:

#(set-global-staff-size 15)

\score {
<<
        \new Voice {
        \key f \major
        \time 3/4
        s4 f'4 g'4 | a'2 c''4 | g'2 a'4 | f'2 e'4
%%...
        \bar"|."
        }
                \addlyrics {
                Bla -- bla, bla -- bla, bla -- bla, bla -- bla
        }
>>
\layout{
        \context { \Staff
                \override VerticalAxisGroup #'minimum-Y-extent = #'(-2 . 2)
                }
        }
}
\paper{
        indent = 0.5 \cm
        line-width=11 \cm
      
        between-system-space = 1.5\cm
        between-system-padding = #1
        myFontSize = #8
        #(define fonts
        (make-pango-font-tree "Univers LT Std"
        "Univers LT Std"
        "Univers LT Std"
        (/ myFontSize 11)
        ))
}
