Barbershop Music Appreciation Day is celebrated on July 13th of each year. Barbershop Music Appreciation Day was established in 2005 in honor of the 60th anniversary of Sweet Adelines International.
The date was Friday, July 13, 1945, when Edna Mae Anderson of Tulsa, Oklahoma, brought a few women together in her home. The women wanted to participate in – the “chord-ringing, fun-filled harmony” that their husbands, members of the men’s Society for the Preservation and Encouragement of Barbershop Quartet Singing in America (SPEBSQSA), were singing. From that meeting grew the nucleus of what was to become Sweet Adelines International.
Barbershop vocal harmony, as codified during the barbershop revival era (1940s–present), is a style of a cappella, 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 bass, except for an infrequent note or two to avoid awkward voice leading, in tags or codas, or when some appropriate embellishment can be created. Occasional traveling may be sung by fewer than four voice parts.
According to the Barbershop Harmony Society (BHS), “Barbershop music features songs with understandable lyrics and easily singable melodies, whose tones clearly define a tonal center and imply major and minor chords and barbershop (dominant and secondary dominant) seventh chords that resolve primarily around the circle of fifths, while making frequent use of other resolutions.”
Slower barbershop songs, especially ballads, often eschew a continuous beat, and notes are often held (or sped up) ad libitum.
The voice parts in barbershop singing do not correspond closely to the correspondingly named voice parts in classical music. Barbershop singing is performed both by men’s and women’s groups; the elements of the barbershop style and the names of the voice parts are the same for both.
