I'm currently in 6th form college (UK) and for part of my Music A-level coursework I have to set words to music. I'm doing my composition in the style of a barbershop quartet.
Could anybody who is familiar with this type of music please help me by telling me the key features of the style. I basically need all the help I can get, so if any of you know the key features of barbershop harmonies please let me know.
Firstly, is barbershop music in a major or minor key mainly?
