Immersed in Mozart – Roberto Prosseda on Recording the Early Sonatas

The Italian pianist Roberto Prosseda has previously recorded Mendelssohn’s complete piano works. Now he is embarking on a new, slightly less encyclopedic but equally ambitious project, that of recording Mozart’s complete sonatas. Read more >>

"Slightly unscrewing tuning pin " (loose tuning pin. a technique of restoration)

Here a complete "scenario" as a way to apply a tighten loose pin:

1. Loosen the pin and, using a thin but hard screwdriver with a thin stinger remove the tip of the string from the hole of a pin (becket).
2. Do not removing the string from a pin with considerable effort compressed fingers, use a T-bar, starting unscrewing tuning pin from the hole. This can be 3-5 or more complete cycles counterclock-wise. It is very important to stop it's when your hand will feels the maximum pressure between a pin and "a body of wood". Should have the feeling that you as pull it's pin like the feeling when we use pliers, pulling a nail out of wood.
3. Set the end of the string into the hole of a pin and gradually use very slow movement, begin to screwing . If this couple string bring almost to the desired tone it's couple pin. Before that as to tune loose pin.

4. Have strong pressure by own hand (fist) directed to the iron plate, gradually and slowly twisting a pin. In the beginning tuning is necessary to tighten a rings string using a screwdriver so it's located as closely as possible to each other. 5. In begin to make tuning couple pin. 6. Set the tone just above the standard pitch, to ensure that "unscrew pin" has enough friction.

7. Set "last and standard pitch "our "tightening pin"

It can make any layman.
Good luck

Unless it's just the recording it sounds like it needs tuning to me. But I'm glad the pin repair worked out ok for you.

Depressing the pedal on an out of tune acoustic piano and playing does not result in tonal color control or add interest, it's called obnoxious.

It's not very good sound and you right says "it needs tuning to me". And for me need it's too. But I made ALL that CAN I do with this piano.
here recording after 5 days

I like the tone of that piano. I think the person playing the piano uses a lot of sustain pedal and that may be what I'm hearing.

When I tune a piano I use a Korg instrument tuner and set the frequency and temperament of the middle two octaves. Then tune by ear in octaves for the rest of the piano. I slightly stretch the upper treble a few beats and tune the deep bass as pure as I can hear it. Then I touch up thirds and fifths slightly if I can't stand them. Usually there will be a third or two that irritate me. It takes very slight adjustment though or you can distort it worse, and when first learning it takes time to isolate the offensive note and also to learn to hear beats.. It took me a long time to hear beats for tuning by ear. Each unison I tune pure after setting single strings of the whole keyboard. My old grand was built in 1898, I keep it at 440 in the summer and let it drop when winter comes and I then tune it to 438. It's a better sounding instrument at 438 than at 440, at least to my ears. Being so old the cabinet swells a lot in summer pulling up the tuning, if let go it will pull itself up to a rough 442, so I level it off periodically during the spring time to 440 and keep it there all summer.

Thank you very much. I like the sound it's piano because a depth here.  Especially  bass region. I agree with your feeling that the girl gave " a lot of sustain pedal", I think.
I use a guitar tuner for my tuning. Of course I check all intervals and I try  to clear unisons. Especially try pay attention the creating a octave. It's OUR ALL!
