Does the electronic keyboard sound exactly like a piano?
Depends. most keyboards use samples to create a specific tone. Those samples are actually single recordings of each note from a real piano. When you play a key, the recorded sound from the same key on the piano is played. But there is a catch! The beauty of a piano is the overtones created by the other strings ringing together. Also, when you lightly play a key on a piano, the tone is different than when you play the same key hard. It is very difficult to recreate that electronically. Some companies come close. Yamaha and Kawai do a good job. So do a few others. Also, the quality of any recreated sound is only as good as the weakest link in the chain. So if you have the most beautiful grand piano sample and play it through a 1 speaker pushed by a poor 2 watt amplifier (exaggeration), it won't be as good as if played through a professional sound system. Hope I helped!
