[Make sure there is a hyphen between bach - and - cantatas]
Choose a cantata, eg BWV180
Choose the Vocal and Piano score option
You should now see the whole vocal score come up as one document. If you, - and
your printer - are ready with about 50 sheets of paper, begin printing. Good advice:
try test printing by choosing one A4 page only. If you have difficulties, contact
the webmaster through the Contact pages. Good luck!
