Guitar! by Smule has players strumming along to the music in an app that combines guitar songs paired with real vocals from Smule’s Sing! Karaoke app, which creates a unique feeling of playing alongside an actual singer. There are multiple songs to play along to, though there is also a freestyle mode for those who just want to play. Players will strum and pick while changing cords and creating vibrato by shaking the phone. Also, as players get better, they’ll be able to rock out even more by unlocking electric guitars.
