Homogeneous and Disparate Music

Homogeneous Musical Combinations
The word homogeneous means "of the same kind." In regards to music, this would mean groupings that involve similar instruments, such as a cappella vocal quartets. Vocals, when described as instruments, are similar sounding, even when each one is singing something entirely different. An example of a homogeneous piece of music is this barbershop quartet cover of "When I'm Sixty Four" by The Beatles. 


When I'm Sixty Four - A Cappella Barbershop Quartet

Unlike instrumental quartets such as strings, brass or woodwind, male barbershop quartets tend to remain within the lower vocal ranges. The vocal range extends from bass up to soprano but this quartet includes bass, baritone and tenor. Instrumental quartets tend to include bass, tenor, alto and soprano. For example, a woodwind quartet typically includes a flute, an oboe, a clarinet and a bassoon. Although these instruments don't correspond exclusively to each register, quartets tend to have a vague register stamp applied to them. 

Homogeneous music also includes other vocal styles such as choir singing and Gregorian chant. In barbershop quartets, such as the one above, the singers tend to sing different melodies that harmonise with each other in order to produce a thicker texture. All members voices have similar timbres but they each sing different rhythms dispersed throughout a song. The voice in the bass register is easily distinguishable from the voice in the highest register of the quartet. This means that the bass vocalist can sing contrapuntal melodies in order to produce a more varied song. This differs from Gregorian chant, where each singer sings the same line with free rhythm and dynamics. Barbershop quartets tend to have a more obvious rhythm.  

Disparate Musical Combinations
The word disparate means "different in kind; not able to be compared." In music, this means instruments of different types and timbres that come together to form a tune. An example of this is hip hop music. Hip hop often includes electronically produced sounds combined with recorded vocals. 


The Pharcyde - Y? (J Dilla Remix)

The example includes a combination Dilla's samples, drum machine beats, synth basslines and loops alongside The Pharcyde members' rapping. The timbre of the vocals is vastly different from the beat, mainly because the beat is noticeably produced by computer technology. Computer technology allows artists more freedom of choice within their music. It allows them to create sounds that are totally unique from acoustic instruments and vocals, which means there are endless possibilities on what can be produced.

The most appealing disparate music tends to be music that includes instruments that complement each other. In this hip hop example, the drum rhythm complements the rhythm of the vocals, giving a stronger beat to follow. Similarly, the lack of melodic lines within the lead vocals leaves more space for the bassline to be emphasised.
