What musical features are found in 'And the glory of the Lord' by Handel?

'And the glory of the Lord' from the oratorio Messiah by G. F. Handel is a chorus from the Baroque era for SATB choir and violins, viola, and continuo bass (cello). The time signature is in 3/4 and the tempo is Allegro and ending with Adagio in the final bars. The structure of the chorus is made up of 4 main musical ideas, melodies 1-4. Melody 1 is 'And the Glory, the glory of the lord', which is syllabic and uses the notes from the major triad, followed by an ascending scale. The second melody sets the words 'shall be revealed' and is, in contrast, very melismatic and scalic. Melody 3 for 'And all flesh shall see it together' uses a repeated descending scale motif, and lastly the fourth melody 'For the mouth of the lord hath spoken it' is made up of monotone repeated notes. Structurally, these four melodies are presented individually and then interweave with each other as the next one enters. Towards the end, all parts are woven together polyphonically and reach a dramatic pause, before a grand plagal cadence to finish.The chorus uses a mixture of homophonic, polyphonic, and monophonic texture in order to create contrast and a richer texture. The melody lines are presented contrapuntally. The tonality of the chorus is A Major but there are modulations to neighbouring keys such as E Major (the dominant). This is the progression of keys throughout the chorus: A Major - E Major - D# Major - A Major - E Major - B Major - E Major - A Major.
