In Music Jam, you play as either Miley Stewart or her alter ego, pop sensation Hannah Montana. As the game unfolds, you'll take on another rising pop singer, Savannah Star, in the music jam video contest. Add to that the problem of Miley's friends being stolen away by a popular new girl in the school and, well, it seems like a girl's work is never done. To develop your musical skills in the game, Music Jam will let you actually play a variety of instruments--from lead or rhythm guitar to bass, and even drums. You'll use a slightly different approach for each instrument, but the common denominator is always the combination of the stylus and touch screen. When playing rhythm guitar to one of Hannah's songs, for example, you'll simply strum the strings of a virtual guitar by moving your stylus across them, changing chords as you go by pressing buttons on the directional pad.
