Continued Construction of the Grand Piano

Hi everybody,
I will be finishing up the construction of all of the different parts of the Grand Piano in this post. I'm going to be focusing on hammers, strings and the keys.
The Strings
The bass strings are made from a round steel wire that is then wound in copper giving a very deep pitch. The treble strings are then made from steel. The treble strings are much shorter on the piano as they give off a quieter sound while the bass strings are much linger and are long enough to touch the end of the piano, this is because they are much louder.

The Hammers

The Hammers, strings and keys need to work together to get the perfect sound. The felt hammer heads are altered by sticking three sharp pins into the felt as this will change how the felt hits the string. 

The Keys

The keys have an action where once it is played the key must come back up the same amount of time it takes to go sown. The weighting of the keys then happens and can take hours to do bearing in mind that there are 88 keys to do!!

After all of the parts are assembled together, a lacquer is painted over the rim and outside of piano. This must take 3 weeks to dry before being cleaned and polished.
