Hello! Not a dumb question. Mostly cosmetic, sometimes you can use a pink rubber eraser to remove the marks made by fingers on the strings but the possibility is there to damage them depending on the acidity of your fingers. However, I've never seen them damaged by being touched too much.
Why are bridle straps needed? Sebastian Erard introduced double repetition mechanism in the grand piano in 1821, and "=" Robert Wornum - the "tape check" mechanism in upright piano in 1826. Robert Wornum constructed your the first upright piano in 1811. J. Hawkins about 1800 and J. Schmidt in 1780 - those upright pianos and the first Wornum's piano (1811) didn't have it yet of bridle straps (tape check) just as old pianoforte in 18th and some oldest in 19th centuries didn't have double repetition too. "(...)The value of this tape lies mainly in the slight extra pull it manages to impart to the hammer butt when the hammer rebounds from the string, and after the back check has caught the hammer and been released by the release of the key. The tape would not have any special. value but for the fact that the hammer, having' been caught by the back check, naturally would hang a little on the release thereof, if it did not receive the gentle pull caused by the fall of the wippen with which the bridle tape connects it. The tape is, in fact, to the upright action what the repetition lever is to the grand. Until these two features had been devised and applied to their corresponding actions, the piano was an extremely imperfect instrument." The upright piano from 1826 and after "(...) owes its present touch effect to the tape just as the touch delicacy of the grand is due to the repetition lever. Of course the grand action is the mor~ delicate and responsive of the two, for it possesses the double repetition. This the upright cannot have, not to mention the fact that the fall of the hammer through gravity is of course far more effective than its retraction by springs. The upright action blocks more easily than does the grand, and finger movement must be higher to secure repetition." The second function of ribbons is "(...)to keep the levers up, and to prevent the jacks getting caught beneath the notches, when the action is removed from the piano and replaced."

Underrated vid thanks for the info
Very helpful! Thank you so much for your excellent videos!

Bravo!! Excellent, thank you!
You're welcome!
3:05 sorry dumb question: does it also damage the strings or change their sound? Or is it strictly cosmetic?

@@MrPianoTech Thanks for the quick reply.👍
I suspected as much, not that "cosmetic" doesn't mean it's not important.

Ottimo tutorial!
Thank you!
Did you go to a school for this trade?
@@Rodney-z5s I did a combination of formal training, training with manufacturers such as Yamaha, and studying with other technicians and piano engineers.
12:00 "If this piano had a sostenuto pedal"
Well, you pointed at it at 7:03, so how did you manage to lose a whole pedal in under five minutes?
@@kd5nrh At “7:03” I stated higher-end pianos have a sostenuto, I never said this one did.
