I think you may be missing a little here.
What is amazing isn't that the flute doesn't make an annoying shrill, but that it's scale is similar to ours.
Beyond us having 12 tones in a scale, the temperament. Simply, the spacing in pitch between the tones.
Even in modern tones we have many examples of different tuning and different scales.
The most common scale and temperament people today recognize is the 12 tones in equal temperament (12-TET). That is the notes are divided equally into 12 steps between the fundamental frequency and its second harmonic. This isn't true for other temperaments. In Equal Temperament it A# and Bb are the same note. That isn't always true for other temperaments. There are pianos made with a split key there, because if you play the wrong one in the wrong musical key it sounds awful or even makes a wolf-tone (what you may call a shrill).
Add to that little bit in western music, modern eastern musical scales and tuning can be vastly different than what we use commonly.
Similar musical tuning and scales implies (doesn't prove) similar harmony and musical constructs.
The music played on that flute may have been more similar to modern western music than Japanese, Arab, Chinese, Aboriginal or Indian music based on its design.
Timers make all the difference.
Last year my home used 622 kWh for the June bill.
This year June was down to 392 kWh!
I haven't noticed a thing.
My computers are on timers... The OS shuts them off before the timer does... then I have to use a timer since the bios doesn't have a wake at time feature... But I set them to power on after power failure.
I put a lot of things on timers now. I just wonder if I am actually wasting electricity putting a CFLs and particularly LED lights on a timer, suspect on the lower wattage ones the timer and the light may be about the same. But with lighting I just want it on without thinking about it.
But basically it's a 37% difference in kWh.
I did this after switching to the 3 tier time-of-use plan and last year's bill was $80.69 and this years was $36.20 for a 45% savings.
And no I'm not an environmentalist, I'm just so cheap I squeeze a quarter 'til the eagle screams

Do not mistake transient governments for the principles on which a nation is founded. I'll take "Life, Liberty, and the Pursuit of Happiness" over "Peace, Order, and Good Government" any day

Doesn't the tendency of an event recurring increase with the passage of time?
No, the likelihood of an event happening stays the same. If an event has a 1/100 chance of happening in a year, it still has a 1/100 chance of happening this year, which ever year this is.
