How I do love technology. There's an app for everything. Some that are fun to check out are the musical apps that give you a drum machine or little single-octave piano. They have several guitar apps as well like the one this dude uses to perform the guitar solo from this Megadeth song.

And here's me who can barely play anything on any app as my fingers are too clumsy on those devices. This has inspired me to make my own. Soon as I rock at something, I'll post the video.
In the meantime - practice.
