The Mills Blue Rhythm Band was an American big band of the 1930s.
The band was formed in Harlem in 1930, with reedman Bingie Madison the first of its many leaders. It started life as the Coconut Grove Orchestra, changing to Mills Blue Rhythm Band when Irving Mills became its manager in 1931. At various times the same group was known as the "Blue Rhythm Band", "Blue Ribbon Band", "Blue Rhythm Boys", "The Blue Racketeers", "Earl Jackson's Musical Champions", "Earl Jackson and his Orchestra", "Duke Wilson and his Ten Blackberries", "King Carter's Royal Orchestra", "Mills Music Masters", "Harlem Hot Shots" and uncredited playing behind Louis Armstrong.
The Mills Blue Rhythm Band were based at The Cotton Club in Manhattan. They worked steadily through the 1930s deputizing for the Duke Ellington and Cab Calloway Orchestras; often taking their undesirable engagements. Violinist Carroll Dickerson briefly fronted the band, followed by Drummer Willie Lynch in 1931 and then compere Jimmy Ferguson (Baron Lee). Edgar Hayes, Eddie Mallory and Dave Nelson all had temporary stints as band leader until Lucky Millinder permanently took over the role in 1934.
The rhythm band is one of the primary methods of introducing children to playing music. Children are given maracas, tambourines, bells, rhythm sticks and other idiophones with which to beat out a simple rhythm while the teacher plays a song, usually on the piano. Alternatively, the teacher does not play a melody but also a rhythm instrument, so that only rhythms are played. Children can also make a rhythm band "just for fun" for themselves, without a teacher.
If the participants like very loud music, noisemakers like the pea whistle, the recorder head joint, the vuvuzela or the ratchet can be included into the rhythm band, as well as other very loud rhythm instruments like the snare drum.
Rhythm bands are usually found in nursery schools or kindergartens, but of course children also can make a rhythm band at home. Melodic instruments are introduced to the children in the first or second year of regular school. But in principle, a rhythm band can be made in every age, with more difficult rhrythms if the participants are older.
