This provides you some of the same expressivity you get on an acoustic piano. Keyboard Instrument Sound Intensity ■ Sound intensity depends on the speed that keys are pressed. People normally believe that the stronger the pressure applied to a piano keyboard, the louder the sound. Actually, however, the intensity of the notes played depends on the speed at which keys are pressed. Notes are louder when keys are pressed quickly, and quieter when keys are pressed slowly. Keeping this in mind as you play a keyboard musical instrument lets you control note volume without striving to apply too much pressure with your fingertips. ■ The playability of an acoustic piano Your Digital Keyboard provides you with key touch that is the next best thing to an acoustic piano.
