changing the String Resonance amount and/or the combinations of notes.

Damper Noise
Damper Noise: The
In the acoustic piano the sustain pedal (or, damper pedal) lifts the dampers from all keys, sustaining all played notes.
Whenever this pedal is pressed or released a typical noise is emitted by the plucking-like effect of the damper felt on
the strings. Moreover such noise is further reverberated because of the resonant characteristic of the piano
construction.
HINTS AND TIPS: The amount of such effect depends from the
sustain pedal operation. A higher velocity corresponds to higher damper noise sound.
−
Damper Resonance
Damper: The
fundamental or overtone frequencies when the sustain pedal is pressed and some strings are sounded.
When one or more notes are played on a piano the vibration is transmitted to all piano parts including the strings
corresponding to keys that are not played. When the sustain pedal is pressed all dampers are lifted, therefore all piano
strings are able to respond to the energy emitted from played notes, as a result they start to slightly vibrate because of
a physical phenomena known as sympathetic resonance. This natural effect replicates exactly what happens inside
an acoustic piano giving beauty and truthfulness to the generated sound.
HINTS AND TIPS: To better appreciate the
then repeat the chord with sustain pedal pressed. In this last case in addition to the played notes you will hear a
background sound like a reverb. This is the
piano strings excited from your chord.

Damper Size
Damper Size: The
time of the piano notes.
Each of the first 67 notes (from A0 up to F#6) is equipped by a damper that has the purpose to stop the sound when a
key is released. The damper is made by a felt that, when it is in contact with the string, absorbs the vibrating energy
causing the end of the sound. The damper size affects the release time of the sound: large dampers absorb more
energy causing shorter release time; small dampers absorb less energy causing longer release time; In the following
animation you can see how the damper size change.
HINTS AND TIPS: The effect of the
