How I did my experiment: I don’t talk at length well and not at all well spontaneously (not knowing what I’m going to say where I just start talking and let whatever comes out).
So, I forced myself to give an answer for: “How to solve anything”.
I had to do it for at least 10 mins.
Once done, I had to fit my spontaneously / forced speaking tempo to a backing track at the correct BPM.
Thankfully, I already knew my comfortable “fast speed” on piano is 270 bpm (arpeggios using triplets at 270 bpm, which works out to 810 bpm really).
So, I did fractions of that. It worked at 270, 135 (1/2), 67.5 (1/4).
But it REALLY stood out at 90 bpm, which is 270/3. 1/3. That makes sense to me as “triplets” (3 in 1) is what I normally like.
OH! This makes sense. (for Theta):
Vanderwolf (1969) made a strong argument that the presence of theta in the hippocampal EEG can be predicted on the basis of what an animal is doing, rather than why the animal is doing it. Active movements such as running, jumping, bar-pressing, or exploratory sniffing are reliably associated with theta; inactive states such as eating or grooming are associated with LIA. Later studies showed that theta frequently begins several hundred milliseconds before the onset of movement, and that it is associated with the intention to move rather than with feedback produced by movement
So in both my speaking and piano playing being at the 270 bpm tempo, which is theta, and theta is “intent to move”, that means my intent to move (words out of my mouth or notes out of my fingers on piano) were in line with my intent tempo, meaning:
OOH – more fractional goodness.
My typing speed at 99%+ accuracy is 110 wpm.
I just looked at what’s the cpm would be (characters per minute).
110 wpm = 550 cpm.
270 bpm * 2 = 540 cpm.
So, I type two characters per beat. My beat. My bpm.
