“Ah, were men's voices like the wood-birds' melody— Each happy note distinct, but all in harmony!”

Context: Love is the most melodious of all harmonies and the sentiment of love is innate. Woman is a delightful instrument of pleasure, but it is necessary to know its trembling strings, to study the position of them, the timid keyboard, the fingering so changeful and capricious which befits it.

Context: Although it is not, abstractedly speaking, of importance to know who first made a most valuable experiment, or to what individual the community is indebted for the invention of the most useful machine, yet the sense of mankind has in this, as in several other things, been in direct opposition to frigid reasoning; and we are pleased with a recollection of benefits, and with rendering honour to the memory of those who bestowed them. Were public benefactors to be allowed to pass away like hewers of wood and drawers of water, without commemoration, genius and enterprise would be deprived of their most coveted distinction, and after-times would lose incentives to that emulation which urges us to cherish and practise what has been worthy of commendation or imitation in our forefathers; and to make their works, which may have served for a light and been useful to the age in which they lived, a guide and a spur to ourselves

A Song for St. Cecilia's Day http://www.englishverse.com/poems/a_song_for_st_cecilias_day_1687 (1687)
Context: From harmony, from heavenly harmony,
This universal frame began:
When nature underneath a heap
Of jarring atoms lay,
And could not heave her head,
The tuneful voice was heard from high,
'Arise, ye more than dead!'
Then cold, and hot, and moist, and dry,
In order to their stations leap,
And Music's power obey.
From harmony, from heavenly harmony,
This universal frame began:
From harmony to harmony
Through all the compass of the notes it ran,
The diapason closing full in Man.

Context: Patterns of gene expression are to organisms as melodies and harmonies are to sonatas. It's all about which sets of proteins appear in a cell at the same time (the chords) and which sets come before or after other sets (the themes) and at what rate they appear (the tempos) and how they modulate one another (the developments and transitions). When these patterns go awry we may see malignancy. When they change by mutation we can get new kinds of organisms. When they work, we get a creature.
