Sam Hubbard, Music Theory Stream Sam has been engrossed in the world of ensemble singing ever since joining his school choir as a young boy. He is an enthusiastic and experienced participant in many different styles of vocal music, including classical choral music, vocal jazz, and (of course) barbershop harmony, which he got hooked on by accident whilst surfing YouTube as a teenager. Nowadays, Sam is active in the barbershop world as a quartet singer, arranger, music judge (with the BABS C&J Team), and late-night tag teacher. He sings with the chorus Hallmark of Harmony and is a member of their music team. As an arranger, Sam writes customised material for quartets and choruses across BABS, LABBS, and Sweet Adelines International. In 2018, he attended the Barbershop Harmony Society’s Harmony University as a recipient of their Lou Perry Arranger Scholarship. Sam studied music and mathematics in a joint-honours BSc course at the University of Leeds, graduating in 2017. The musical half of this degree had a focus on theory, which remains one of his chief interests. Sam is a huge advocate of the value that learning music theory can have for barbershoppers, and is passionate about sharing music theory with other people.
