Some tuners rely on machines to help them tune. It is through using comparison checks that the piano can be tuned by ear. The beat rate/second will be approximately 7, 11, 15, or “fast, faster, and fastest.” If any one of those intervals creates a slow beat rate, then you know the interval of the third is not correct. F4-A4 A4 – C#4 and C# – F5, are most often used. The third (F4 A4) finds a complement in the sixth (F4 D4) and beats one beat per second (BPS) faster.Ī tuner will often set three intervals of thirds in the temperament in order to establish a rough estimate of a proper tuning. A tenth (an octave plus a third) will beat a hair faster than a third in the octave below. Thirds will beat faster as you go up the scale. There are countless relationships between the notes. By adjusting the F2 A4 interval, you can fine tune A4 to the rate of the fork more precisely.Ĭhecks like these are used throughout the piano. If the beat rate is slower, then the reverse is true. If the beat rate of A4 F2 is faster than the rate of the tuning fork, then the interval is wide A4 is a little bit on the sharp side. Since A4 = tuning fork A, it should beat wildly with F2 at the same rate as A4 F2. Once A4 is set, then the rate of the tuning fork equals the rate of A4.įor a fine tuning adjustment, I compare the fork frequency to F2. I set A4 to 440 using a tuning fork (and my brain). In the photo above I am comparing note F2 to note A4. Stated simply, if note x and note y are properly tuned, they can each be checked for accuracy by comparing each to note z. There are lot of tricks used by piano tuners. ![]()
