A versatile electronic sheet music device with an improved navigation system, comprising a memory having a storage of all musical scores and of an index of said musical scores. The device comprises a wide angle visibility display. The display is capable of displaying the notes arranged by musical bar and/or by page. A central processing unit receives information from an input device and from a foot actuated input device, touch-screen, and/or a microphone, processes said information and communicates the output information to the display. The foot actuated input device is capable of communicating to the central processing unit an identity of any musical bar and/or any page of the notes of the musical score. The foot actuator comprises at least one pedal that allows selection of any of at least ten characters, an "Enter" input signal and a mode selection. The commands and outputs are processed by software.
