Especially, watch the professionals. Plays by Shakespeare, Marlowe, and others were often written in poetic forms. Watch how the real professionals act them out. Watch how professional singers handle poetry and songs.

You can also watch the non-professionals. What differences do you notice? Are you doing things that the pros don’t do? Are you not doing some things they do and you should do? As with writing poetry, critiquing performances will help you learn how to perform better.
