The slap and pop method, or "thumbstyle", most associated with funk, uses tones and percussive sounds achieved by striking, thumping, or "slapping" a string with the thumb and snapping (or "popping") a string or strings with the index or middle fingers. Bassists often interpolate left hand-muted "ghost notes" between the slaps and pops to achieve a rapid percussive effect, and after a note is slapped or popped, the fretting hand may cause other notes to sound by using "hammer-ons", "pull-offs", or a left-hand glissando (slide). Larry Graham of Sly and the Family Stone and Graham Central Station was an early innovator of the slap style, and Louis Johnson of The Brothers Johnson is also credited as an early slap bass player.
In general, the sounds produced by a digital piano are based on sampling, by which real piano sound samples are stored in ROM. The samples stored in digital pianos are usually of very precision recording and made using high-quality pianos, expensive microphones, and high-quality preamps in a professional recording studio. ROM may include multiple samples for the same keystroke, attempting to reproduce diversity observed on the real piano, but the number of these recorded alternatives is limited.
Prior to the development of the drum set, drums and cymbals used in military and orchestral music settings were played separately by different percussionists; if the score called for bass drum, triangle and cymbals, three percussionists would be hired to play these three instruments. In the 1840s, percussionists began to experiment with foot pedals as a way to enable them to play more than one instrument, but these devices would not be mass-produced for another 75 years. By the 1860s, percussionists started combining multiple drums into a set. The bass drum, snare drum, cymbals, and other percussion instruments were all struck with hand-held drum sticks. Drummers in musical theater shows and stage shows, where the budget for pit orchestras was often limited, contributed to the creation of the drum set by developing techniques and devices that would enable them to cover the roles of multiple percussionists.
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.
Many drummers extend their kits from this basic configuration, adding more drums, more cymbals, and many other instruments including pitched percussion. In some styles of music, particular extensions are normal. For example, rock and heavy metal drummers make use of double bass drums, which can be achieved with either a second bass drum or a remote double foot pedal. Some progressive drummers may include orchestral percussion such as gongs and tubular bells in their rig. Some performers, such as some rockabilly drummers, play small kits that omit elements from the basic setup. Some drum kit players may have other roles in the band, such as providing backup vocals, or less commonly, lead vocals.
In Canada, the Humber College Institute of Technology & Advanced Learning offers an Advanced Diploma (a three-year program) in jazz and commercial music. The program accepts performers who play bass, guitar, keyboard, drums, melody instruments (e.g., saxophone, flute, violin) and who sing. Students get private lessons and perform in 40 student ensembles.
Most drummers have a single main ride, located near their right hand—within easy playing reach, as it is used very regularly—most often a 20" sizing but, 16"-24" diameters are not uncommon. It is most often a heavy, or medium-weighted cymbal that cuts through other instrumental sounds, but some drummers use a swish cymbal, sizzle cymbal or other exotic or lighter metal ride, as the main or only ride in their kit, particularly for jazz, gospel or ballad/folk sounds. In the 1960s Ringo Starr used a sizzle cymbal as a second ride, particularly during guitar solos.
Just like the acoustic instruments they're derived from, digital pianos come in different sizes. They also offer dozens of options for your perusal, so you can weigh all kinds of factors to find the right model for you. For instance, if you're looking to pack a lot of piano into as small a space as possible, consider instruments such as the Williams Allegro 88-Key Digital Piano or the Casio CDP-120. These are fairly compact pianos, but that doesn't limit the breadth of their samples and sound settings.
