The best places to get MuseScore help fast are:
The handbook appears online on the MuseScore.org and there’s also a PDF version which can be downloaded. You can also access the handbook from within MuseScore itself, in the Help menu or in the Learn and Support tab of the MuseScore Connect panel (MuseScore version 1.1).
The MuseScore forums are very active and questions posted there are answered quickly. Be sure to do a search for your question first before posting a new one since someone may have already solved your problem.
I’m aso happy to answer questions where possible, so feel free to leave a comment or contact me by filling out the form on this page. I’ll do my best to get back to you quickly.
