Hi, if you are a beginner or expert harmonica player you are welcome here.
I hope that you will contribute music for harmonica with tabs added, This has been made simpler by code that has been written by a developer on this site.
Add the Plugins, and when you run the plugin the tabs are automatically inserted in your score for you, Have a look at this page for more information, http://musescore.org/en/project/harmonicatablature
I look forward to seeing some contributions soon. My main interest is in Scottish music, I have found the MuseScore will directly import files in the BMW \ BWW format many of these are available on the web, but take care many have errors so choose your source with care, Bob.
