There is a widely held ‘myth’ called ‘the missing fundamental’ in the bass register of a piano.
This myth is very unfortunate and very untrue.
I am here today to dispel that myth once and for all with irrefutable evidence.
Is the fundamental present all the way down to A0. Of course!
This evidence was collected from a PianoSens sensor on a large concert grand, a Fazioli F308. However, I did a similar experiment over 15 years ago using an instrumentation quality microphone on a Steinway D and got a similar result.
As you watch the video and hear the explanation, you will clearly and unequivocally see that there are clean, pristine periods of repetition at the fundamental frequency all the way down to A0.
You will see the spectral view of the time domain showing that the fundamental A0 is down only 9 dB from the 2nd harmonic A1. A factor of 9 dB is still very easily heard by human perception even at that frequency.
I also show just how 'messy' the transient response is from the hammer strike moment, compared with the PianoSens sensor.
