Info about Pianos
What you should know about piano keyboard
The piano keyboard contains keys that mach each of the 12 notes, but there are more than 12 keys, because some of them are longer, other are also shorter, but all of them are repeating in an interval of an octave. When the singer is pressing the key, the piano is producing a sound. The piano keyboard is formed by white keys and black keys. The white keys represent 7 of the notes, the notes that are the longer ones. They are positioned in a specific way, the lowest ones are on the left. Usually these white notes are made from ivory, because they are much more used. The black notes are made from wood that is then covered in wood. The wood is then colored in black. The black notes are the ones that don’t appertain in the C major scale.
If you have played at least one a piano keyboard, you would have noticed that if you press harder the key, it will sound also louder. When you are playing the piano, it is important to play accurate but also in tempo, how the score says you should. To learn this skill, it takes years of practice. The player has to learn how to use it hands, so he can play better. Also, if you have a dynamic keyboard (the dynamic keyboard has keys that if they are pressed harder, the sound produced is louder). So that multiple keys can be played at once, to make a nice music, and some of them need to be pressed harder and also some of them need to be pressed harder. So the singer needs to learn how to use multiple fingers of his hand, in many ways. The piano keyboard is used most time with 2 hands, and it isn’t so difficult at it seems, because the right hand is playing the melody itself and the left hand is adding the bass notes, etc
The piano keyboard has developed very much from the time it was first developed. At first, in the 19th century when the first piano was created, it had 88 keys. In the present there are some pianos, like the Bösendorfer piano, that have even more keys, a number of 97 keys. The octave span distances can be different also, because the keys can have different width. So, for example, the modern pianos have a distance of approximately 164 mm.
