For those of you who have asked for a sample of my tuning, here is one, courtesy of a local PBS station:

BDB,

Could you clue me in as to where the piano's microphones were located?

Why I'm asking: granted, I'm only listening on smallish headphones, but from what I hear, the voicings in the 3rd and the 4th octave are carrying through very warmly, while the 5th octave, especially at forte, sounds quite harsh, almost metallic. I was wondering whether that's to do with the recording, or my playback, or whether it was perhaps voiced that way deliberately?

I really cannot, as I tuned and went home, but it is usually miked with a couple of mikes under the lid. The piano is an old Kawai 600 from the 1960s, which has seen a lot of use. I first tuned it for a show with Woody Herman, and when I tell people that now, they ask, "Who is Woody Herman?" It is kind of harsh in the upper registers, but as I often say, there are limits to how much voicing one can do. The television lights have an affect, too. It was warmer than usual on the stage.

Bumping this for Maximillyan.

If possible, I like to hear pianos with no mic interface. I realize that's not possible in this case. If I do hear a recording, I withhold any critique unless the unisons and octaves are howling like a pack of wolves. Mics, room acoustics, and recording equipment mess up any good sound if they aren't perfect, and they seldom are.

As there :

What size is that piano ?

On the BDB record, unison seem to shorten the tone somehow (sorry)

Issac, can you explain what it is about a unison that will cause the tone to shorten?

Quicker decay, perhaps.

Yes , Chris, I (thanks Dan) think that when we say "tune the attack" it is not the attack per se that is empowered by the tuning, more the decay moment, the attack is then cleaned because energy is immediately given to a larger spectra, then, the power allowed immediately can be regulated by tuning the decay more or less "late" . The range of possibilities is not that large and depends of the differences in spectras, iH, voicing, (string lenght eveness in the unison , string quality and hammer quality)

You can strive to obtain much power immediately, or allow the attack to "enlarge" , this gIves more control on tone to the pianist. I believe that basically the playing hand that tells the brain when to tune (hence the possibility to tune with earplugs up to some point, as the thickening of tone is perceived)

The idea "hear 2 strings as it was one" is good as long as the string imagined is thickened and more present, more lively.

The tone can be explosive but at the beginning of the aftersound.

I have no other easy trick than to evaluate how the tone escapes and "tune the attack", but to do so we need to focus on coupling at a certain level, when adfing the 3 string straightness of tone can be balanced.

Tuning good intruments make this easier to perceive.
Then, voicing can be envisaged leaving more power at the attack.
