HOW LONG DID MAGNA CARTA LAST
I am not sure exactly how long they will last, but they will last for at least 1 year.
A year
A regular piano tuning usually lasts 6 months to 1 year. I tune pianos here in Phoenix, AZ. - Perfect Piano Tuning, L.L.C. Addendum: If, on the other hand you meant: "How long will my piano stay in tune once tuned?" that is variable by the climate where you live, and how much the piano is played (which is actually good for it). A professional will want their piano tuned at least once every six months. For the average person who owns and plays a piano, once a year is typical - and it should be re-tuned in the same season it was originally tuned in. Climate can have a big effect on how long your piano will stay in tune, especially if the humidity fluctuates frequently. In dry conditions the pitch becomes flat. In humid conditions it becomes sharp. Extreme changes in humidity can also cause physical damage to many parts of your instrument, so it is something you should be mindful of.
