I&#x27;ve been using MuseScore for several years to arrange vocal and piano scores. It&#x27;s really good!<p>The best thing about it being free is not so much that it is free for me, as the arranger (I&#x27;ve bought score editing software before). It is the fact that I can actually send the digital scores to the singers, and tell them they can use the same software for free to rehearse on their own (e.g., setting the volume of their voice louder, etc.).
