We all have our own rhythm -perhaps some might call it our voice but I think there is a subtle difference. Our rhythm and the rhythms of our work are not neccessarily the same but all of our works will contain at least an echo of our essential rhythm.
Let me quote Virginia Woolf on rhythm:
As for the mot juste, you are quite wrong. Style is a very simple matter; it is all rhythm. Once you get that, you can’t use the wrong words. But on the other hand here I am sitting after half the morning, crammed with ideas, and visions, and so on, and can’t dislodge them, for lack of the right rhythm. Now this is very profound, what rhythm is, and goes far deeper than words. A sight, an emotion, creates this wave in the mind, long before it makes words to fit it…Of course we understand rhythm in music and perhaps we all get it to some degree in poetry but what is it in prose? I think one way to consider it is to understand it as the 'gait' of the piece. Even if several people are dancing a polka they will approach it differently - some will be quite jerky-herky and some will be quick but fluid in their movements. If you ride (horses that is) you quickly come to know that one horse's canter is not the same as another's. Rhythm is our word choice, how we build sentences, the construction of our works in a larger scale as well as up close and mostly, it is the effect it has on the reader. Is the reader captured up and swept along with long galloping sentences carrying her to a certain pitch of emotion or is she lullabied, rocked and then flung onto the hard pavement of the story?
— Virginia Woolf, In a letter to Vita Sackville-West, 1926
Rhythm is a promise and when you find the rhythm of the piece you are creating, then you have found the luminous heart of it and you must honour that above everything else in your art. Trusting yourself, trusting your ear to hear when you are in the rhythm and when you have slipped out of it, is the craft we need to hone
