The trio are currently in their home studio working on the follow-up to 2009's Lines, Vines and Trying Times, which is expected to be released later this year.
The clip sees Joe Jonas humming along to a disco riff, while Nick Jonas plays it on keyboard and then records it.
The video - which was shot by Kevin Jonas and uploaded to Twitter - seems to suggest that the group are heading into an uptempo classic disco direction.
Nick recently revealed that the Jonas Brothers have thought about the "overall tone" of their next record and intend to take their time making it to get it just right.
