A multi-talented musician has become a viral star by becoming a literal one-man orchestra, recording all 70 parts of a piece of music in his bedroom.

Ben Morfitt, 24, spent a month filming himself playing each one of the parts before editing the final piece together. The final video splices together the audio and video of him with every instrument, as well as taking up the conductor’s baton.

"It took a full month to film," he said. "I used about three-and-a-half hours' footage for the final piece and there's about ten times that in out-takes."

Morfitt’s YouTube channel had already attracted viewers from all over the world, as he arranged covers of music used in computer-game soundtracks.

"I wanted to make the transition from my covers to original so thought what better way than a one-man orchestra," he said.

The video was pieced together by first creating a backdrop of the empty Albemarle Centre in Hull, England. Then Morfitt performed and recorded each instrument’s part in front of a green screen set up in his bedroom, before editing all the parts together.

"I thought about copying and pasting some aspects of the filming but it didn't look natural," he said. "I filmed the empty hall at Albemarle, but apart from that it was filmed in my bedroom.

"There were times I went wrong, so it had to be recorded again. There were a few times when my cat came into the shot when I was recording."

Morfitt, a skilled musician who can play more than 50 instruments, makes a living as a professional composer. You can watch his one-man orchestra below:
