Descending octaves are always half the frequency. Ascending octaves are always twice the frequency of the starting note. When we speak of just/pure intervals, we are talking about the relationship between frequencies. Nevertheless, "just", "pure", and "perfect" happen to be the same when applied to octaves. "Just" and "pure" are synonyms while "perfect" has a different technical meaning in music. In equal temperament, octaves aren't merely perfect they are "just" or "pure". This may be true, but the practical reality for my cheap baby grand is that the backlash in the tuning pegs and the stability of each string's pitch doesn't allow such tiny adjustments to stay stable. I've seen claims that each unison should actually be slightly detuned, and that this affects the sustain of the tone. Over almost the entire keyboard, you can actually do fine just by tuning to an electronic tuner. The stretching of intervals is only desirable in the very high treble and very low bass, because those are the strings that have a significant amount of inharmonicity in their overtones. I believed these two claims until I actually started tuning my own piano. From a lot of the written descriptions you see out there, you'd imagine that (1) every interval on a piano was stretched by some fixed percentage, and also that (2) piano tuning has to proceed through a circle of fifths, tuning by ear using beats. This is not nearly as complicated as a lot of people would have you believe. what, exactly? The distance between the notes in the lower half of the piano?
to get the octaves and fifths to agree with one another), a piano tuner lengthens the. (I'm not sure: which fifths? Like, the tonic of the second octave and the fifth of the third octave? Or is it the fifths in the sense that you play a note and then go +5, and then again +5, and so forth?) However, when you divide each octave into 12 semi-tones, and tune it mechanically, there's going to be a problem with the fifths. If you then play the same C and any other C, it'll still sound perfect. To one's ear, it is essentially the same note. There's no conflict between the two notes. When you play an octave on the piano (say, a C and the C following it), it sounds perfect. I've been trying to make sense of it all, and now I find myself thoroughly confused.

The stretch files allow for a very sweet sounding tuning.I get the feeling that the actual explanation is a lot simpler than what the manuals and textbooks offer. This is an excellent device for tuning pianos. The strobes allow you to tune in a very intuitive way. I didn't like that at first, but wow, when I tuned the treble section the first time and experienced how quickly and accurately this baby helped me tune I was over it! Once you're aware of it, it's OK but I expected it to be perfectly silent and it freaked me out when I first powered it up. I do wish someone had prepared me for the noise of the mechanical strobes, this thing doesn't run silently, you can hear the strobe discs turning.

I also use manual mode in my tunings so I won't comment on the auto tune functions. I recommend buying this with both foot switch accessories if you are tuning pianos. I love that it has built in stretch and temperament files. An electronic tuner is never a substitute for the skills of the piano tuner and there are always judgment calls and compromises to be made by ear, but honestly this tuner is AWESOME! I'm very impressed, it allows me to tune quickly and accurately because it's immune to background noise and false beats. The built in stretch and temperament files make it easy to tune and gives excellent results. I use this for tuning pianos - it is extremely accurate and easy to use.
