Tweaks have been made to how instruments can be played, particularly with regard to expanding the range of difficulty in both directions. A new Easy Rhythm difficult level replaces notes with measure lines that signify the beat of the song. It's ideal for those not so musically inclined, letting you hit whatever notes on the guitar or drums as long as you keep the right beat. Additionally, more complex note patterns have been written for bass players and more improvisation is encouraged when playing drums. Other changes include activating Star Power on drums with a simultaneous hit on both cymbal pads and the ability to work through the career mode on bass.

The biggest addition to the series comes in being able to record your own music. Jam mode allows you to hop on for an improvisational session solo or with the entire band. If you're interested in recording a tune, heading over to Quick Play mode lets you record a short song for instant playback. Those really into creating their own music will get a lot of mileage out of Advanced Studio mode, which contains a entire suite of recording options that enable you to write, arrange, and record original songs. An online community service entitled "GH Tunes" hopes to facilitate original song sharing among players. While we only caught a glimpse of it, Advanced Studio mode looks pretty complex. It's innovate quality may end up being overshadowed by how difficult it'll be to actually use.

When it comes to actual licensed tunes, Activision is largely keeping quiet on the full soundtrack. Expect more details to trickle out as the game inches toward a release this holiday season.
