Opera singers are classically trained vocal professionals who have mastered the art of acting and stage presence. On stage, the opera performer must sing over a full orchestra which is a highly-specialized skill involving an understanding of fundamental frequencies and their acoustic powers; elevated harmonics and resonance tuning. Actors portray characters in stories such as plays, musicals, films, television shows and radio shows. They engage with the audience and convince them through altered speech patterns, hand gestures and more that they truly are the character. When necessary, actors also change their appearance such as their hair color or body weight to physically portray and embody their character.
