Gone are the days of beginning guitar and needing to purchase a $20 tuner and $20 metronome. It is no longer necessary to rely on recordings, books, and music teachers to learn songs and skills on the guitar. Thanks to the popularity of smart phones and tablets there are many resources which make it is easy to learn and get better at music.

Here are 10 essential music and guitar apps for iPad and iPhone. Many of these apps (or similar apps) are also available for Android devices.
