I am a big guitar freak. I play guitar all the time. A good friend for guitar learners is Guitar Pro on windows. Guitar pro is basically a tool which shows musical notations, plays them, show the notation on guitar tabs, change tempo etc. It helps beginners a lot.
Today, I felt the need to use it again, but I didn’t want to logon to windows for doing that. I knew there had to be an alternative in Ubuntu (Geeks play guitar too :D). Fortunately, I found two packages in repos which could work similar and better than guitar pro. Best of all, they are free.
To install them, type the following in terminal:
$ sudo apt-get install tuxguitar
For kguitar (It is for Kubuntu/KDE users):
$ sudo apt-get install kguitar
I found tuxguitar to be more feature-rich and bug free. Try ’em both to see what suits you.
