Although singers train to get a wide range (good top and bottom notes) they cannot be expected to sing any role in their voice range. For example: some sopranos may have big, dramatic voices, suitable for parts like Tosca in Puccini’s opera "Tosca". Some may have a very light and high voice, called “coloratura”, suitable for parts like the Queen of the Night in Mozart’s "Magic Flute". Some may have a medium range, called mezzo-soprano, suitable for parts like Carmen in Bizet’s opera "Carmen".
