Program is a program, and keyboard is a keyboard instrument.

Keyboard instruments are musical instruments with keys arranged like a piano keyboard. Each key on these instruments has a fixed pitch, so they can be used to play any piece of music within their range. There are often syringes or other devices for syringes under the keys. When using a keyboard instrument, the performer does not directly strike the strings of the instrument to produce vibrations, but uses the keys to produce sound through the mechanical mechanism or electronic components within the instrument.

In the keyboard instrument family, all instruments have one common feature, which is the keyboard. However, their sound production methods are subtly different. For example, the piano is a percussion instrument, while the organ is a reed instrument, and the electronic keyboard uses electricity to produce sound, etc.

Commonly used keyboard instruments include piano, organ, accordion, and electric organ.
