Default font for lyric text

If you want to change the standard font for a score, you should set it for the empty score.

It will then apply to all staves as you enter text. If you change your mind half way through entering the text, it is best to finish with the currently selected standard font and afterwards select menu edit | mark | all and then select menu format | voices (lyric verses) | lyric verses, where you can select a different font.
