Rhythm is very important in the Hallelujah. For example, on the fourth bar of the SATB chorus, there is a dotted quarter note, then three eighth notes, followed by rest to create suspense. The rhythm of 4'33" is slightly harder to determine. There is not exactly any written rhythm, but the definition of rhythm is "The lengths of sounds and silences and their arrangements." I guess, then the rhythm must be four minutes thirty three seconds of rest.
They next element is dynamics. For example, "Hallelujah" in the first few bars are very loud and strong. Later on, "He shall reign for ever and ever" is very soft and gets louder and louder so that the climax can be reached. 4'33" is a very different piece and is silent It is not exactly exciting because of the absence of climaxes. There are only subtle noises heard, such as soft shifting of seats, louder coughing, etc.
The fifth element is tone colour, or timbre. Hallelujah uses SATB chorus, the string orchestra, continuo, oboes, bassoons, trumpets, and timpani. There are a few brass solos
