Gyalis

"Gyalis" is a song by American singer Capella Grey. It was released on January 4, 2021, through Capitol Records and Allepac the Family. Rappers Mannie Fresh, Lil Wayne and Juvenile are credited as co-writers of the song as it samples Juvenile's "Back That Azz Up". The song went viral on TikTok, and gained over 18.1 million streams on Spotify by September 2021, reaching number 10 on the Billboard Hot R&B/Hip-Hop Songs chart.

Background and composition
Grey told Billboard of the inspiration behind the song, explaining: "I was in LA [Los Angeles] at the time. I made the beat and got in the booth real quick, and after I recorded on it, I added a little more to the beat and then recorded on it some more and mixed it on my laptop. It just popped in my head, it wasn't too much of a buildup or anything like that. When the 'Back That Azz Up' sample plays in the club, it's a big moment. Turning that into a whole uptown type of feel, I felt like that really shook the room. Once I got the inspiration for it, I just went for it."

The song samples "Back That Azz Up" (1999) by Juvenile. It is written in the key of A♭ major, with a tempo of 96 beats per minute.

Music video
An accompanying video was released on August 26, 2021, and directed by Brennan Rowe. It was filmed in Grey's hometown, Bronx, and "captures the heart and soul of New York's uptown movement". It features Grey "vibing in a sea of fans who eagerly came out take part in the shoot".
