Answer
By emphasizing melodic simplicity, Horace Silver adapted from bebop to hard bop. In bebop, complex and intricate melodies are common, but in hard bop, simpler melodies are more common. This is because hard bop is more focused on rhythm and groove than bebop, which is more focused on melody and improvisation. By emphasizing melodic simplicity, Silver was able to create a more accessible and danceable style of music.
