As the frequncy starts to increase, a pulse of increasing speed can be heard between the two tones, going from a slow wah-wah-wah to a rapid thrumming at 20Hz. One of the sources is then gradually increased in frequency to about 460Hz, then back down to 440Hz. In the video, two sources are playing a 440Hz sine wave tone at the start. Y ou might - or might not - enjoy a YouTube video I made to demonstrate the phenomenon of "beats", basic to all piano tuning. There is a more about tuning theory and the complexity of the piano scale in the About Tuning page of this site. To the individual piano and in manipulating the tuning lever to achieve aĬertain aspects and can measure the piano in ways that contribute to a superb They do not replace the skill and discernment of the tuner in responding So today’s Electronic Tuning Devices and Apps are extremely sophisticatedĪnd very far removed from earlier technology.
Vibrating strings across the whole range of the piano and then suggest optimal degrees ModernĮTDs and ETAs – those shown here – can analyse the component frequencies of the Stretch means that tuning is adjusted to take account of the deviation of the strings' partials from theoretical perfect harmonics. The point of all this is that piano tuners need to apply stretch, Referred to as Partials, to distinguish them from theoretical perfect The actual frequencies produced in a vibrating string are How a manufacturer incorporates inharmonicity aspects into the scaling of a piano has a substantial effect on its tonal qualities (along with many other tonal factors of course). They produce are slightly higher than the perfect theoretical frequencies ofĬalled Inharmonicity, and it gets greater towards the low bass and highĭealing with Inharmonicity is a major aspect of piano scaleĭesign and of tuning. Lengths are relatively stiff (its more complex than this!) and the frequencies Something like this happens with the Harmonics within a Length stretched between two fence posts. This short piece would seem much less flexible – much stiffer somehow than the long Now imaging cutting a short length of it, perhaps about 6 inches (15cm). If it was tight enough, it might even produce a musical tone. Here is a YouTube video of the same thing:īut over a good length like that, you could probably “twang” it quiteĮasily. Click and hold on each 'string' to hear the tone, IF you are listening on a laptop or notebook, you might not hear the fundamental as 100Hz may be too low for the speakers:
TUNE LAB PIANO TUNER SERIES
There is a very nice Harmonic Series here, starting at 100Hz. To learn more about this, you can obtain one of the technical books. Theįrequencies of the Harmonic Series of all the notes interact with each other in very complex ways. This series of movements within a string isĮvery string in each of the piano’s 88 notes produces its The Third Harmonic, three times, and so on. Second Harmonic is the frequency of the string moving as two halves – that’s Harmonic is called the Fundamental, the whole length of the string (in the YouTube

Professional Tuning Device or App that you might see your piano technician Technicians today, are vastly different from what existed fifty, or even thirty,Īn ill-informed way, resulting in dull, lifeless tunings and giving clients a badįirst, we’ll have a quick look at the professional devicesĪnd Apps, and then we’ll discuss a bit about tuning.įor reasons we’ll go into further down this page, basicĬhromatic tuning devices or Apps for guitars etc are useless for piano tuning. The electronic software and hardware options available to piano Piano strings, Harmonicsand Partials will be needed. On this page we will look at ETDs and ETAs. It seems there are misconceptions about the use ofĮlectronic Tuning Devices (ETDs) and Electronic Tuning Apps (ETAs).
