Traditional digital pianos vaguely resemble an electronic organ or a spinet harpsichord but usually lacking a fully enclosed lower section, while some models are based on the casework of traditional upright pianos with a fully enclosed bottom part and pedals that look like actual piano pedals. An opposite and recent trend is to produce an instrument which has a unique and distinctive appearance, unobtainable with a conventional instrument. Yamaha , Kawai and Casio makes a model which is designed to stand against a wall and is far shallower from keyboard to back than any possible upright design, as well as shorter height.
The fretting hand can add vibrato to a plucked or picked note, either a gentle, narrow vibrato or a more exaggerated, wide vibrato with bigger pitch variations. For fretted basses, vibrato is always an alternation between the pitch of the note and a slightly higher pitch. For fretless basses, the player can use this style of vibrato, or they can alternate between the note and a slightly lower pitch, as is done with the double bass and on other unfretted stringed instruments. While vibrato is mostly done on "stopped" notes—that is, notes that are pressed down on the fingerboard—open strings can also be vibratoed by pressing down on the string behind the nut. As well, the fretting hand can be used to "bend" a plucked or picked note up in pitch, by pushing or pulling the string so that the note sounds at a higher pitch. To create the opposite effect, a "bend down", the string is pushed to a higher pitch before being plucked or picked and then allowed to fall to the lower, regular pitch after it is sounded. Though rare, some bassists may use a tremolo bar-equipped bass to produce the same effect.
In most drum kits and drum/percussion kits cymbals are as important as the drums themselves. The oldest idiophones in music are cymbals, and were used throughout the ancient Near East, very early in the Bronze Age period. Cymbals are most associated with Turkey and Turkish craftsmanship, where Zildjian (the name means cymbal smith) has predominantly made them since 1623.
It comes with 4 strings that make it the ideal choice for anyone who is trying out the bass guitar for the first time. The 4 strings mean that the guitar will have a narrower body hence convenient for younger guitarists with smaller hands. The E-A-D-G format is also easy to master and play. The body is quite lightweight which gives you the comfortable feel as you use it with minimal fatigue.
Strumming, usually with finger nails, is a common technique on acoustic guitar, but it is not a commonly used technique for bass. However, notable examples are Stanley Clarke's bass playing on the introduction to "School Days", on the album of the same name, and Lemmy who was noted for his use of chords, often playing the bass like a rhythm guitar.
Extended-range basses (ERBs) are basses with six to twelve strings—with the additional strings used for range rather than unison or octave pairs. A seven-string bass (B0–E1–A1–D2–G2–C3–F3) was built by luthier Michael Tobias in 1987. This instrument, commissioned by bassist Garry Goodman, was an early example of a bass with more than six single course strings. In 1999 South American ERB player Igor Saavedra designed one of the first eight-string ERBs known, and asked Luthier Alfonso Iturra to build it for him.  Conklin builds custom ERB basses. The Guitarbass is a ten-string instrument with four bass strings (tuned E–A–D–G) and six guitar strings (tuned E–A–D–G–B–E). Luthier Michael Adler built the first eleven-string bass in 2004 and completed the first single-course 12-string bass in 2005. Adler's 11- and 12-string instruments have the same range as a grand piano. Subcontrabasses, such as C♯–F♯–B–E (the lowest string, C♯0 being at 17.32 Hz at around the limit of human hearing) have been created. Ibanez had released SR7VIISC in 2009, featuring a 30-inch (762 mm) scale and narrower width, and tuned as B–E–A–D–G–C–E; the company dubbed it a cross between bass and guitar.[better source needed]
The bass drum (also known as the "kick drum") provides a regular but often-varied foundation to the rhythm. The bass drum is the lowest pitched drum and usually provides the basic beat or timing element with basic pulse patterns. Some drummers may use two or more bass drums or use a double bass drum pedal with a single bass drum. Double bass drumming is an important technique in many heavy metal genres. Using a double bass drum pedal enables a drummer to play a double bass drum style with only one bass drum, saving space in recording/performance areas and reducing time and effort during set-up, taking down, and transportation.
