01 / A different reference
A small shift.
A fresh listen.
For Echad, tuning is another creative choice. A starting point for exploring the character of a sound.
What does 432 Hz mean?
432 Hz and 440 Hz are two reference frequencies for the note A above middle C. Choosing a reference sets the pitch around which the other notes are tuned.
At 432 Hz, that A is slightly lower than at 440 Hz. The composition can stay the same while its overall pitch shifts.
Start with your ears.
The comparison here uses two simple sine tones. Listen to each one in turn, at a comfortable volume, and notice the change in pitch.
A single tone is only a starting point. In a recording, instruments, arrangement, rhythm and production all contribute to the way the music feels.
