Rock Band 4 offers backward compatibility with content and hardware from previous versions of Rock Band within the same console family wireless guitar and drum controllers from PlayStation 3 and Xbox 360 versions of Rock Band can be used on the PS4 and Xbox One versions (with Xbox One requiring a newly produced USB dongle and PS4 not requiring any new hardware), and DLC songs purchased on prior installments on PS3 and Xbox 360 can be re-downloaded at no extra charge on PS4 and Xbox One in a ported form that supports the game's features. Announced on March 5, 2015, Rock Band 4 refocuses on the core gameplay of the franchise, reducing the emphasis on musical instruction that was employed by its predecessor, Rock Band 3, while emphasizing the game's social interactions, as well as new features enabling players to incorporate improvisation into their performance-such as "freestyle solos" on guitar, and "freeform melodies" on multi-part vocals. Rock Band 4 represented Harmonix's return to the franchise after an almost three-year hiatus, following the diminishing popularity of the rhythm game market that started in 2009.
