Which sound to use for voice part when practicing singing?

I'd like to use Musescore to practice singing of folk / pop / rock songs (eg Joni Mitchell, Bruce Springsteen, ...).
I'd like the voice part to give me easily recognizable notes along which I can sing the song.
1) Which sound from Musescore would you recomment using for the voice part, assuming the instrument part uses a piano (or guitar) sound?
2) Similarly, which soundfont available somwhere else would you recommend using for the voice part?
