![]() ![]() This result is called Mersenne's equation (sometimes known as the Mersenne-Taylor equation or the Ideal String equation). Put another way, this explains what are called Mersenne's Laws, viz., that the frequency is inversely proportional to the length, proportional to the square root of the tension and inversely proportional to the square root of the mass per unit length. Where F is the fundamental frequency of the note, L is the length of the string, T is the amount of tension on the string, and µ is the mass of the string per unit length. Notes in the bass may be slightly flat of the "theoretically correct" frequency, those in the treble slightly sharp.Īt this point, enter the hero of our story - Marin Mersenne (1588-1648), who was a French monk, theologian, scientist, mathematician and "Renaissance Man", particularly noted for his contribution to acoustic theory. It should be noted that, on any well-tuned piano, the actual frequencies of notes outside the middle octaves may deviate somewhat from this, because of octave "stretching" - which makes the piano sound much better. With the pitch of the note, there are two ways to approach the matter - if you are so minded, you could use a chromatic tuner to ascertain the precise pitch of the note, or you could simply work on the assumption that the piano is at standard pitch (A above Middle C = 440Hz) which very often will be the case (though it is not uncommon for older pianos to be at a lower pitch).Ī table of theoretically correct frequencies for each note on a piano can be found here. The exact pitch of the note (in Hertz or cycles per second).The diameter of the wire - this should ideally be measured with a micrometer to get an accurate reading, since a small error may make a significant difference to the calculation and,.The speaking length of the piano string - that is the length between the capo bar and the upper bridge pin.To do this, we will need to know three things: In the last post, I promised that I would explain how to calculate the tension on a piano string, so I'm going to do that now. In any case, I thought it might be fun to have a look at Victor Borge's attempt here to conduct the Boston Symphony Orchestra back in 1986 - and I hope you all have an enjoyable festive season. So I am always very delighted to visit whenever you need me! If he had been, he might have disagreed with this statement - in fact it's a good idea to have your piano tuned at least once a year to keep the tuning in good order, but I have customers who prefer more regular tunings to keep their piano in top condition all the time. Now despite his pianistic talent Mr Borge was not, as far as I know, ever a piano tuner. "Santa Claus has the right idea - visit people once a year." We appreciate this is not ideal and thank you for your understanding and continued support.Just a note to wish customers, colleagues, friends and family all the best for Christmas and the New Year.Īs some of you may already know from previous posts, I'm very fond of the humour of the famous pianist Victor Borge, but I couldn't find any specifically Christmas-related sketches by him.
