YES i found it: Mathematical tools such as spectrum analysis, wavelet decomposition and multifractals can be used to analyse sentence text length variability.
Analyze all the great masterpieces of well-known writers by means of their "word rhythm" and see if they have anything in common. I think there's probably some kind of "golden ratio" like as for pics. I'm surprised nobody has done this :/
I claim that a book has a higher attraction for the reader if the word rhythm is more melodic aka the metre is in music. Not too long & too short. Apparently, there are no analyses available, find this only for music not for text on the net.
After a long test, I found the best music player for my Raspi2, "cmus" running within the bash needs only 5.2% system performance. Perfect for running in the background for my writing project.
Unbelievable, but it really does work. It's much better if you put a face towel under the keyboard. It feels much better than the keyboard does without it. Incredible.
Fun fact: it writes itself more pleasantly with a soft woollen cap on the head. Somehow I can think better. I know it's crazy, but when it helps, you like to use it.
