Today I want to share some nice software. If you are into writing your music on a staff paper you might consider Musescore. It is free and has a very god help community and facebook page. Having said that I must add that the app for your smartphone has a small price. You can upload your score to be able to share it or just access it from another location. Klick on Musescore to read more and download.
The score shown in my previous post, My Attempt at Arranging ,is made in Musescore.
