The piano has 31 sharp keys and 44 flat keys. The 7 letters are C, D, E, F, G, A, B. The electric keyboard has 3 pedals and the wooden upright has 2 pedals. We sit on a piano stool while playing the piano. The wooden upright is bigger than the electric keyboard. At Beo Ceol piano classes, you can see the keys moving on the inside of the piano. The hammers move and hit the strings inside the piano. The hammers are white and the strings are silver. The piano here is 100 years old. On the electric keyboard, you can change the way it sounds.
