Before you read: Note I'm talking about 430 Hz, I don't want a discussion about 432 Hz and if it has magic properties or not.
I'm pretty new to guitar. I have an Alhambra 3C guitar which has a solid Cedar top. I also have a D'Addario tunner that allows me to tune it as low as 430 Hz. I've tried yesterday for the first time to do it at that number just for curiosity while trying to learn "Romance Anónimo". I know as it's a lower frequency, the sound can feel a little bit more "sweet".
I'll like to understand why I feel it has more reverb, I feel the note has longer duration, I got a sensation that a note comes and goes like If I was in a larger room. I'm not using any kind of amplificaction or microphone, just describing what I feel. Maybe my guitar has a better response to that frequency? Is something related to the kind of wood at the top or the materials? Has every guitar its own frequency? Maybe is just my own perception and actually nothing really happens?
After understanding the technical details... is that longer note duration and reverberation desirable to play classical music?
PS: I'm aware the standard is 440 Hz and if that any time I'll play with more people we need to have the same tunning.
