Yes, they could have chosen whatever. But it's no use crying over spoilt milk or water under the bridge.
If you take physics for limitations, the lowest note should be the threshold of human hearing at 20 Hz. 32Hz as a basis is still an arbitrary choice. As a matter of fact, whatever you pick it will be an arbitrary choice. Be it what the tuning reference frequency is, or what the names of the notes are.Pashkuli wrote: Tue Jan 04, 2022 11:16 am This is also related to why I have chosen B (first consonant letter in most European languages) to start where the old C is. I started form a physical and also mathematical point of view.
Let's start with silence: 0Hz
First integer tone would be: 1Hz
Its renova (octave): 1 × 2 = 2Hz
Next renova: 4Hz
Next: 8Hz, 16Hz, 32Hz (this is whereabout human hearing kicks in)
32Hz (of a tuning as it is now today as A = 440Hz, or 432 or 445) will fall between what is known as B and C.
There are systems with relative names (do re mi fa so is the same whatever the tonic or root of the scale is, chords in Roman numerals are also relative so if a singer wants it lower or higher you can still use the same lead sheet with chords) and systems with absolute names. Both have advantages and drawbacks. Nothing is ideal.
