In the 2010s, some drummers use a variety of auxiliary percussion instruments, found objects, and electronics as part of their "drum" kits. Popular electronics include: electronic sound modules; laptop computers used to activate loops, sequences and samples; metronomes and tempo meters; recording devices; and personal sound reinforcement equipment (e.g., a small PA system to amplify electronic drums and provide a monitor).
Another design consideration for the bass is whether to use frets on the fingerboard. On a fretted bass, the metal frets divide the fingerboard into semitone divisions (as on an electric guitar or acoustic guitar). Fretless basses have a distinct sound, because the absence of frets means that the string must be pressed down directly onto the wood of the fingerboard with the fingers, as with the double bass. The string buzzes against the wood and is somewhat muted because the sounding portion of the string is in direct contact with the flesh of the player's finger. The fretless bass lets players use expressive approaches such as glissando (sliding up or down in pitch, with all of the pitches in between sounding), and vibrato (in which the player rocks a finger that is stopping a string to oscillate the pitch slightly). Fretless players can also play microtones, or temperaments other than equal temperament, such as just intonation.
The bare minimum requirements for a budget digital piano are to have 88 keys (the same number found on traditional acoustic pianos) and internal speakers to facilitate practicing without an amplifier. Beyond that, some amount of weighted key action (either semi-weighted or hammer action, more on this in a moment) and an accurate piano sound were the primary deciding factors for our picks. An included stand and sustain pedal were not requirements, as aftermarket options are readily available and inexpensive. (We discuss some options below.)
Maybe you've already got a specific brand in mind and want to see all the digital pianos they offer. All you have to do is click on the brand on the left hand side of the screen and within a few moments you'll have access to everything that's available. For that matter, you can always play is safe and stick to the top-rated items…and there are plenty of those in this selection.
