That also made them pretty finicky, changing moisture and temperature would have a significant effect on the pitch of the piano. At that time 'standard pitch' was about A4@423 Hz, considerably below what it is today (A4@440), which lessened the problems somewhat but if you wanted to have your instrument well tuned you had better learn how to tune it yourself.
For harpsichord players (the predecessor to the piano) today self tuning is still the standard.
Piano history is fascinating, if you are interested in the subject I'd recommend reading 'Of men, women and pianos' by Arthur Loesser. It's an old book but a fantastic source of historical information about the development of the piano/grand piano.
And regarding your comment about bars and musicians, I was reminded about a scene from “El Mariachi” in which the guy walks into a bar trying to get a job and is faced with the bartender saying “why would I need a mariachi when I can get the full band”, followed by the demo from a digital keyboard :)
So yeah, the point I tried to make was that despite the changes brought about by technology, the social aspect to music still lives on, and I personally love the private side of it that came thanks to technology. Not going to argue about the difficulty of making a living as a musician, but life is all about change and careers come and go.
