Exams and concerts take place in concert halls to present concert grand piano. Just so musicians can hear the future his game in this "live" sound, which I have already mentioned. In my own music school students playing the piano in the exams at the end of each quarter, plus a mandatory dress rehearsal in the concert hall before each performance. Best students participated in numerous concerts and had the opportunity to play on stage much more often. And in order to play the piano, takes some effort when you press the keys, which do not train on a lightweight keyboard synthesizer, as an effort by pressing the keys synthesizer is less than when playing on an acoustic piano or piano. Obtain the output third: the synthesizer is not suitable for children entering the music school. Therefore, for students music schools, as well as for training of professional musicians, producers of electronic keyboard instruments have developed a special kind of electronic keyboard instruments – digital piano.
Their key difference from synthesizer – a complete imitation of hammer mechanism with the software exactly the same force when pressing the keys as if playing on an acoustic piano or piano. In any case, explain what Hammer mechanism. The principle of the piano is that when you press a button, you actually push a little hammer that strikes the taut strings inside and get the desired sound. Of course, that this hammer push, you need a little more effort than simply pressing a button, which is essentially a key synthesizer.
