Up and at 'em, people! These splines aren't going to reticulate themselves!

@freemo there's seriously a whole community around Tetris, like soo many games!

Check this, it's amazing 😆

@freemo A 13yrd old kid beat Tetris!

but a news ancor from Sky had to mock it.. :nkoFacepalm2:

it's time that pro gaming is also taken seriously like chess and darts etc

"Scientific pitch was originally proposed in 1713 by French physicist Joseph Sauveur and based on the numerically convenient frequency of 256 Hz for middle C,"

https://en.m.wikipedia.org/wiki/C_(musical_note)#Middle_C

@freemo We can say with certainty that concert pitch (actually set by A4 being standardized at 440hz today) was higher in the past - as high as A = 401hz. Not every instrument is tunable. Bells and some double reed instruments will never change pitch over their life times. By looking at bells from the 15th and 16th c we can tell that music was in general pitched somewhat higher then today.

The big innovation in modern tuning is equal temperament. All modern digital tuning has an precisely equal ratio between each half step. (about 1.059 to 1) This makes music work like you describe. Start on any pitch and the music will sound the same if the relative intervals are followed.

However much more than absolute pitch, relative pitch is hard without modern measurement methods, Prior to the 1700s the most common tuning was to tune in pure 5ths where every 5th was tuned by ear to a 2/3 ratio. It works pretty well until you get to the point where you go from the end of the circle of fifths back to what should be the note you started on. You find you are off by a scotch less than a quarter tone. This terrible sounding interval is a "wolf fifth" because it howls.

In pure fifths each key had its own flavor and so it was important to play a piece in the key it was written in. The major thirds that define the modern major chords are the most effected by these variations which explains why many pieced before JS Back and company are dominated by 4ths and 5ths that are safer in a pure-fifths tuning.

Bach's innovation which caught on across western music was to "fudge the thirds" to make them all sound similar - giving us the last common tuning the so called well-tempered tuning.

@freemo It probably went like this:

Person 1: Your talk of counting vibrations of a twine is witchcraft.

Person 2: No, it makes a difference. Watch: (vibrates string at 261.63 Hz) Seeee?

Person 1: C? That is absurd! Graphemes are for scribes, not bards.

Person 2: And judgment is for judges, not peasants.

Person 1: ...Tell me more about your black magic.
