What is a touch sensitive piano keyboard?

A touch sensitive piano keyboard, also known as a velocity-sensitive or dynamic keyboard, is a type of piano keyboard that can detect the force or velocity with which a key is pressed. This allows for a more expressive and nuanced performance, as the pianist can control the dynamics of the notes they play by varying the amount of pressure they apply to the keys.

Touch sensitive piano keyboards are typically used in electronic pianos, digital pianos, and some higher-end acoustic pianos. They work by using sensors to measure the speed at which each key is depressed. This information is then used to control the volume and tone of the note that is played.

The sensitivity of a touch sensitive piano keyboard can be adjusted to suit the player's preferences. Some keyboards also offer different velocity curves, which affect the way the keyboard responds to different levels of pressure. This allows the pianist to customize the keyboard to their playing style.

Touch sensitive piano keyboards can be a valuable tool for pianists of all levels of experience. They can help pianists to develop a more expressive and controlled playing technique, and can also be used to create a wider range of musical effects.
