I think it's extremely obvious why people expect to perceive (and therefore experience) much larger differences between vintage/famous instruments and those less so and don't really get why it's a conversation that would last much time at all :lol:
RE: Music as science though. Obviously it's MUCH more scientific than most people will grasp. But I think people overlook just how much science there is in almost everyone's playing. Aside from the construction of instruments themselves, which is obviously massively scientific or they couldn't even be tuned, every scale you're familiar with is mathematical. Whilst your phrasing might not be, every note choice is a scientific one - whether you think of it as science or whether it just feels right. Knowing that C, D, E, F, G, A and B will all sit happily on top of a C major chord IS scientific knowledge - even if you only know those notes and that chord as shapes on a fretboard or even just as a sound and feel in your head.
