Pedals
There are three pedals on the piano. The one on the left is for softening the sound, the one in the middle is for keeping the current note in its original sound and also softening the noise. The one on the right is for creating the tone's echo and to lengthen the note. The pedals are made of solid brass.

piano keys
Each of Steinway's 88 keys is made of Bavarian spruce with a polymer surface.The polymer key surfaces are more durable; the white keys do not yellow over time and are easier to replace than the ivory that used to be used for the keys.
Each of the keys delivers its movement to a small, felt- covered wooden hammerwhich strikes one, two or three strings when the note is played.
German silver spruce or Bavarian spruce- a tall spruce with blue-green needles and dense conic crown; older trees become columnar with lower branches sweeping downward.
