The snare drum is the heart of the drum kit, particularly in rock, due its utility of providing the backbeat. When applied in this fashion, it supplies strong regular accents, played by the left hand (if right handed), and the backbone for many fills. Its distinctive sound can be attributed to the bed of stiff snare wires held under tension to the underside of the lower drum head. When the stiff wire are "engaged" (held under tension), they vibrate with the top (snare-side) drum skin (head), creating a snappy, staccato buzzing sound, along with the sound of the stick striking the batter head.
An LCD readout and a few more buttons on the control panel would go a long way toward making the keyboard’s options easier to use. The metronome function especially could be more user friendly. It has 10 speed presets, labeled 0-9, with a + and – for adjustment. These are selectable with the Function button and a key press. While practicing and deciding on tempo, most students find it more beneficial to know the exact BPM (beats per minute), which is impossible here using the built-in metronome.
Another common form is the stage piano, designed for use with live performances, professional audio, or in recording studio. This type of digital piano normally makes no attempt to imitate the physical appearance of an acoustic piano, rather resembling a generic synthesizer or music workstation. A distinguishing feature of most stage pianos is a lack of internal loudspeakers and amplification - it is normally assumed that a powerful keyboard amplifier or PA system will be used. However, some stage pianos are equipped with powered speakers.
