So there are other ways to tune the "perfect" octaves, you can match the fourth partial of the low note with the second partial of the high note. Start in the middle of the piano, and continue to the ends, and you get a stretched tuning. If you tune an octave interval on the piano so that there is no beating between the second partial of the low note and the fundamental of the upper note, then the interval will be slightly stretched - larger than a simple multiply by two. Arthur Reblitz and some findable references online indicate that all of the overtones of a real piano string are sharper than perfect mathematical multiples of the fundamental frequency - even the second partial (the octave above the fundamental). Since real piano strings have thickness, distributed mass, and stiffness, the overtones are never perfect multiples of the fundamental frequency.
So the Stroboscope is a valuable tool for mere mortals. "beat" heard from nearly-coincident partials/overtones). The Stroboscope is a tool that can provide help to somebody who does not have the ear training and experience to tune intervals by ear (using the
PETERSON STROBE TUNER 490 FULL
I also assume that the human piano tuner would have intuitive ideas just by looking at the piano (a tiny console or spinet will have a vastly different string scale than a full upright a 4.5' baby grand will have a vastly different string scale than a 9' grand).īut I think that the real value of having the upper partials easily viewable would be to quickly resolve problems, or more likely - quickly tune intervals. I think the spinning rings on a stroboscopic tuner may provide some hints as to the general nature of the individual instrument: the stringing scale, and the string gauges or stiffness. With a real-live stringed instrument, the upper partials or overtones are very interesting to the human piano tuner. (As George Takei said from the back seat: "I read." That is my only qualification with regard to piano tuning or stroboscopic tuners.) SteveO, please identify any foolishness in my text below, and elaborate if possible. I was hoping that PianoTuner SteveO would answer the question, because I have scant qualifications in this arena. QuoteWhat would you do with that information?What would you do with information about the overtones?
PETERSON STROBE TUNER 490 SOFTWARE
What's funny is, I can't write the name of the software or the forum will reject my post, presumably because it looks like spam. It's got lots of other stuff that I haven't explored including an overtone graph. I've used its waveform display to inform my voicing process and I use its volume graph to help me equalize the pickup placement. In addition to all that, the tuner I use now provides other information I really like. (That's actually just an oscilloscope program, not the tuner I currently use) Plus, the big monitor display is nicer to look at than a handheld device. The computer in my shop is wired into the amplification system so using software tuners is actually easier than hooking up stand-alone units. After using the Strobo-Flip for a while, I wanted to see if anything else could do better. Particularly in the treble, they all have trouble locking onto the fundamental pitch.
Why did you abandon yours to move on to a software tuner?Īlmost every tuner I've tried has struggled to provide meaningful information about the entire range of a Seventy Three.
