Sympathetic resonance on an acoustic piano

That was quick! Love you!

There's a great lot of interesting things you can do with sympathetic resonance on a piano, unfortunately there's very little about it on youtube... Some additional things i found particularly interesting while experimenting and researching: 1.: Depressing many of the low keys silently (for example with the arm) and then holding them with the sostenuto pedal will cause a *lot* of beautiful resonance when you play higher notes, like in George Crumb's "Pastorale (from the Kingdom of Atlantis, ca. 10,000 B.C.)" from Makrokosmos 1 kzbin.info/www/bejne/pnqohoZmYql3mdU 2.: Using smaller silent clusters in different ranges of the keyboard will result in slightly different resonances depending on which keys are depressed silently. Generally, depressing the lowest keys silently and then playing on other keys will result in a much more "distant" and "wider" sounding resonance than if you depress a bunch of keys just about an octave below the played keys, in which case the resonance sounds "closer" in my opinion. Sciarrino's 5th piano sonata demonstrates this effect to a small degree, however the differences of the resonances are extremely subtle because he mostly uses silent keys rather at the very bottom of the piano's range. I can't recall a piece that does it in a more elaborate manner though so this will have to do for now kzbin.info/www/bejne/oqOwpol8eNF1aKM 3.: While there's not as much resonance when you play a key *lower* than the one you hold silently, again using many silent keys can create a very cool and long shimmering kind of sound, especially when playing the lowest notes on the keyboard. An example of this is the beginning of Sciarrino's 2nd piano sonata kzbin.info/www/bejne/qaXEhIqYhbCmnaM 4.: When holding a silent key a perfect fifth or fourth above or below the played note, the resulting sound will be the lowest common overtone between the silent key and the played note. So for example when silently depressing F3 and G3 and then playing C4, you'll hear a C5 and G5 resonating. Major and minor thirds are significantly less audible unfortunately. Off the top of my head I don't recall any piece that makes use of this technique but I might write one soon, in that case if i remember i might link it here

Great notes and ideas!

Don't get that with a digital piano :-) Stylewarning Gould in no time

pretty sure roland digitals have sympathetic resonance because they're almost fully modeled , some high end digitals of kawai and yamaha also have it since they have a hybrid sound engine with both modeling and sampling.

Some VST have sympathetic ressonances only. But it's possible to add some other important ressonances that occur in an accoustic instrument. The messy sound of a pressed pedal while playing some repeated chords, means to hold up to 3500 (or even more) notes of ressonances to mimick an accoustic piano flavour. No physical modelling does that, not even close. I've achieved it through Kontakt VST host programming, and the add ot a lot of mechanical sounds such as pedals, hammers, and a lot of leverages that occur in an accoustic. The moat important are the messy ressonances due to the full strings excitement during the pedalling. Thoee have been also programmed, and I called them antipathetic ressonances. Those messy ressonances are comparable to the added dirt that gives a lifelike look to a 3d rendering image (otherwise clean and sterile).
