I'm not sure I agree entirely with this. Historically, pianos haven't been widely owned, and performances haven't been widely attended. Although I would guess ownership is probably more evenly distributed now than ever before (especially considering high quality digital pianos). Piano (orchestra in general) does seem to infiltrate common culture fairly pervasively (at least american) through movies. Maybe it could even be argued that it's more culturally prevalent, but just less prominent.
