Optek Music Systems, Inc., has announced Guitar Tunes, an innovation for learning to play guitar. This app is for guitar players who want to learn how to play songs in their iTunes library. As you listen to your original iTunes music, the onscreen interactive fretboard will display fingering positions for lead, rhythm or bass guitar parts in real time. Features of the new Guitar Tunes app include tempo control, identification of original artist tuning, interactive onscreen Smart Fretboard, lefty mode, footswitch control and an “Easy Chords” feature for the beginning guitar player.
