The digital piano is a specific kind of electronic keyboard that acts as a compact and lightweight alternative to a standard piano. Today's digital pianos feature hammer action keys (88-key being the norm) to emulate the sound and playability of their acoustic counterparts very accurately; some models can even replicate the sound of a pipe organ, Hammond organ and harpsichord. They have many other advantages as well: digital pianos are more affordable, their volume can be controlled and they never have to be tuned. Most digital pianos even have a headphone option for musicians who live in apartments where volume might be an issue. Because of these many benefits, digital pianos are often preferred over acoustic pianos by music educators and their pupils - this includes for amateur performances and school recitals.
If you really want to distinguish yourself as a bassist, it can pay to think outside the box and go for something a bit less traditional. For example, there are musical styles and occasions where an electric bass may be slightly out of place. In those cases, you can turn to an acoustic-electric bass. These have a classic sound all their own, and if you're headed to a festival or singing around a campfire, they'll do the job even without an amplifier handy.
I have been playing piano since the early 1980s, and I earned a Bachelor of Music with an audio production and piano focus from Ithaca College as well as a Masters in Music in keyboard collaborative arts from the University of Southern California. For the past 20 years, I’ve been a professional music director and have performed myriad musical styles on different instruments in concert halls and on nightclub stages. I also taught music for 10 years at a private Los Angeles middle and high school.
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.
