Though he's only a sophomore, Walker Harnden's college career is already starting on a high note -- literally.
According to the Lake Wiley Pilot, the University of North Carolina School of the Arts student set a Guinness world record for whistling an impressive B7, the highest note ever known to be whistled. The 19-year-old broke the record in November of last year, and his achievement was made official 12 weeks later
Standing on stage at a piano with two judges, Walker works his way up the note and hits it like a boss. Watch in the video above.
Fellow whistlers, you've met your match.
