Electronic keyboards having 88 keys are used by music artists.  A switch is placed under each key in the keyboard. When we press on the key, the switch under the key gets connected to the circuit and produces sound. A matrix system is used to connect 88 keys in the keyboard using wires. In fact the printed circuit board (PCB) has tracks instead of wires for connecting the switches on the keyboard. An integrated circuit in the keyboard is programmed to scan the keys continuously. When we press a key, the corresponding key is pressed and relevant note is produced.  Hence, we hear a sound on pressing a key on the keyboard.

In order to use the piano keyboard, we should understand the sound produced by each key. You may hear a loud sound on pressing the key hardly. If you want a light sound, press the key with less pressure. Hence you can make different sounds for each key by pressing it hardly or lightly. You can make a flute sound or pipe sound by pressing the appropriate keys.

If you are interested in learning the piano, take training from professionals in the music field. Also you need to practice to get familiarized with the sounds produced by each key on the keyboard. An 88 keyboard has a simple layout. It may be difficult to learn in the beginning, but you would feel easy once you practice.

Use both of your hands simultaneously to make different sounds. The instruments fitted with keyboards require finger techniques to press lightly or harder for generating different sounds. Treble chords are located on the right side of your keyboard whereas bass chords are situated on the left side. So, use both of your hands at the same time to generate a different tune.
