Ballet in black and white: the ‘piano reduction’
For ballet rehearsals in theatres around the world the piano has long been the musical instrument of choice. To engage orchestras to do the detailed, volatile work required in routine rehearsals would be impractical and prohibitively costly, and only at the dress rehearsal will dancers and the orchestra finally come together. The music at all earlier rehearsals is provided through a specially written version of the score called a ‘piano reduction’.
