Being a piano tuner and rebuilder for the last 20 years, I have come across this problem many times in the past. The answer is really quite simple and a good technician would be able to pick it out in a heartbeat. When you play, as an amatuer (I assume) you attack the keys with less force and vigor than the technician. Also, you may use the damper pedal differently as well. These playing technique changes are why it doesn't happen when he plays. You need to demonstrate the sticking keys for him/her yourself. Then, they can see what is happening and correct it. Just as a guess on my part, the problem is probably one of these: Your key bushings are sticking, some of the bridle tapes inside (uprights only) have broken, (again uprights) the hammer return spring for a given note has slipped out of place or broken. Each of these problems represent a quick and virtually free repair as the correction of one of these things on just one or two notes take seconds to minutes. Even if the entire action is involved, they still won't need more than a day to make it all nice for you.
when you strike a piano key you get a musical note out of the piano.
The key of a piano connects to a system of levers which moves a small hammer that strikes a wire inside the piano. The wire will then vibrate and make a sound. That sound is then amplified by the wooden body of the piano, which resonates with the wire.
A piano produces sound just like a guitar. Inside piano either grand or upright has piano strings attached inside with every keys. When you hit a certain key, the strings vibrate creating sound that is very pleasing in the ear.
When you press a key on the keyboard (of a piano), this enables a little hammer inside to strike on a string that produces the correct note.
When you press a key on the piano, it causes the hammer-action to strike the corresponding string in the piano. This string vibrates and disrupts the air around it, creating sound.

To make the sound sound loud, press harder down on the key. To make it sound quieter (piano) press lighter down on the key.

When you press down on the key of a piano, it causes a lever to move a hammer. The hammer then strikes a string that produces the sound.
If a piano key is not producing any sound, it may be due to a problem with the key mechanism or the hammer hitting the string. You can try gently cleaning the key and checking for any obstructions. If that doesn't work, you may need to have a professional piano technician inspect and repair the key.
If a piano key makes no sound, it may be due to a problem with the hammer or the felt pad underneath it. You can try gently cleaning the key and checking for any obstructions. If the issue persists, it may require professional repair by a piano technician.
if you have a piano then press a black key. it also depends on the key you are pressing too, as different keys make different sounds.
When a key in the piano is pressed down, it activates a particular wooden hammer inside the piano, hitting a particular string. When you lift your finger off the key, a damper hold the string to stop it from vibrating, thus stopping the sound.
A piano makes sound by hitting the strings every time a key is pressed. A harpsichord makes sound by plucking the strings every time a key is pressed.
To play G on the piano, locate the black key to the right of the white key G. Press down on the black key to produce the sound of G.
I play the piano, and I'll answer the question. The piano has numerous thin, long strings inside it. When you press a key, a little soft-headed mallet hits one of the strings-thus producing sound. And when the key is let go of, a damper stops the sound from ringing or continuing on.
