What aspects of communication have remained the same?

I understand that communication has changed, mostly due to advances in technology, but what aspects have remaind the same? I already know posted mail hasn't really changed, but is there anything else?

Music has remained unchanged. For as long as humanity was able to speak its first words and hum its first tunes, music has been a constant method in communicating feelings and thoughts.
