text: # Rhythmicana
  
  Henry Cowell's 1938 work Rhythmicana is a suite of piano pieces centered on polyrhythms and dissonant counterpoint. It is known for its unusual time signatures, with the first two movements being in $^1$ $_1$ time, and the third movement having the polymeter of $^3$ $_4$ in the right hand and $^5$ $_4$ in the left.
  
  ## Background
  
  Cowell had already used the title for his rhythmicon concerto seven years earlier. The complexity results from Cowell's lifelong preoccupation with rhythmic exploration. The piece is dedicated to J. M. Beyer.
