Composed means calm and in control of yourself when everything around you says panic. The pilot's voice over the intercom with one engine gone: flat, unhurried, composed.
It is about how you appear, not what you feel inside — someone can be terrified and still look composed. The noun is composure, which you keep, regain, or lose. Composed has a second job that has nothing to do with calm: composed of means made up of, and it always takes OF and always sits in the passive. The committee is composed of six members; water is composed of hydrogen and oxygen. Do not write the committee composes of six members. And a piece of music that has been written is composed as well, by a composer.
