Chief Xian aTunde Adjuah (/ˈzaɪ.ən/[5]) (born March 31, 1983,[6] formerly Christian Scott)[5] is an American jazz trumpeter, multi-instrumentalist, composer, and producer.

[14][15] Adjuah was born on March 31, 1983, in New Orleans, Louisiana,[16] to Cara Harrison and Clinton Scott III.

[17] He attended the New Orleans Center for Creative Arts (NOCCA) for high school and studied jazz under the guidance of program directors Clyde Kerr, Jr. and Kent Jordan.

[17] Adjuah appeared on Harrison Jr.’s albums Paradise Found and Kind of New after joining his uncle's quintet at age 16.

[25] Of this album, NPR raved "[Adjuah] Ushers In New Era of Jazz.”[26] He was named one of Ebony's 30 Young Leaders Under 30 in 2007.

[27] 2010 saw the release of Yesterday You Said Tomorrow, which received an Edison Award, and the naissance of Adjuah's "Stretch Music" concept.

[8] Public radio station WNYC's Soundcheck has described Stretch Music as a fusion of "Trap Music (Southern hiphop, mixed with techno, dub, and dutch house), traditional West African percussion and New Orleanian Afro-Native American styles.

The group spent a week recording with Cuban musicians Rember Duharte and Harold Lopez Nussa in Havana, Cuba.

"[50] His tilted-bell trumpet often garners comparisons to those played by Dizzy Gillespie, which featured bells bent upward at a 45-degree angle.

[52][53] The Reverse Flugel, which Adams markets as the Adjuah Trumpet, is an "inverted flugelhorn with shepherd’s crooks"[54] that is able to sound notes in a higher register.

Adjuah is the grandson of Big Chief Donald Harrison Sr. and the nephew of jazz saxophonist-composer, NEA Jazz Master Big Chief Donald Harrison, Jr. Adjuah's family lineage comes from the Maroon culture and Mardi Gras Indian tradition of New Orleans (Adjuah has said that he considers "Mardi Gras Indian" a pejorative term and prefers "Afro New Orleanian or Black Indian."[60]).

His maternal grandfather, Donald Harrison Sr., who began masking in 1949,[61] led three Mardi Gras Indian tribes[62] before founding and leading the Guardians of the Flame in 1988.

[63] His maternal uncle Donald Harrison Jr. is Big Chief of the Congo Square Nation Afro-New Orleans Cultural Group.

[69] In 2023, Adjuah was named Grand Griot of New Orleans at the Maafa Commemoration hosted by the Ashe Cultural Arts Center,[15][70] a position previously held by his maternal grandmother Guardians Institute founder Herreast Harrison.
