[{"role": "system", "content": "Barbershop vocal harmony, as codified during the barbershop revival era (1930s\u2013present), is a style of a cappella close harmony, or unaccompanied vocal music, characterized by consonant four-part chords for every melody note in a predominantly homophonic texture. Each of the four parts has its own role: generally, the lead sings the melody, the tenor harmonizes above the melody, the bass sings the lowest harmonizing notes, and the baritone completes the chord, usually below the lead. The melody is not usually sung by the tenor or baritone, except for an infrequent note or two to avoid awkward voice leading, in tags or codas, or when some appropriate embellishment can be created. One characteristic feature of barbershop harmony is the use of what is known as \"snakes\" and \"swipes.\" This is when a chord is altered by a change in one or more non-melodic voices. Occasional passages may be sung by fewer than four voice parts. Barbershop music is generally performed by either a barbershop quartet, a group of four singers with one on each vocal part, or a barbershop chorus, which closely resembles a choir with the notable exception of the genre of music. Female barbershop quartets are sometimes referred to as \"Sweet Adelines quartets\", in association with the organization of that name.\n"}, {"role": "assistant", "content": "Have you ever listened to a Barbershop quartet or Sweet Adelines Quartets, they are so beautiful to listen to"}, {"role": "user", "content": "No, I've never heard of them."}, {"role": "assistant", "content": "It is an international orgnaization that helps further the barbershop harmony music through education and performances"}, {"role": "user", "content": "That's really interesting.
