Eight and twelve-string models are both built on the same "course string" concept found on twelve-string guitars, where sets of strings are spaced together in groups of two or three that are primarily played simultaneously. These instruments typically have one of the strings in each course tuned an octave above the 'standard' string, although a fifth above is also used. Instruments with ten and fifteen strings, grouped in five courses, also exist, as do "extended-range basses" or ERBs with non-coursed string counts rivaling those of coursed-string basses.
The PX-160 comes with the square SP-3 damper (sustain) pedal. It does the job but is far from an authentic piano experience. There are other piano-style pedals available, such as the M-Audio SP-2, that are nicer to play and don’t slide around as much. Casio offers the optional SP-33 pedal unit, which has a three-pedal configuration with separate soft, sostenuto, and sustain pedals—the traditional three-pedal setup found on most pianos. In duet play mode, the left and right pedals serve as damper pedals for their respective sides of the keyboard. The downside of the SP-33 is that it can be used only with Casio’s CS-67 stand (the two are also available together as a package).
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 some styles of music, drummers use electronic effects on drums, such as individual noise gates that mute the attached microphone when the signal is below a threshold volume. This allows the sound engineer to use a higher overall volume for the drum kit by reducing the number of "active" mics which could produce unwanted feedback at any one time. When a drum kit is entirely miked and amplified through the sound reinforcement system, the drummer or the sound engineer can add other electronic effects to the drum sound, such as reverb or digital delay.
The bass guitar is an electric instrument that performs in both lead and backing roles. They are commonly used across a huge variety of musical genres and are attractive for their versatility, sound, and design. Manufacturers such as Fender and Ibanez offer a variety of both modern and vintage bass guitars, and each has multiple models with their own characteristics.
Some bassists use other types of tuning to extend the range or get other benefits, such as providing multiple octaves of notes at any given position, or a larger tonal range. Instrument types or tunings used for this purpose include basses with fewer than four strings (one-string bass guitars, two-string bass guitars, three-string bass guitars [tuned to E–A–D]) and alternative tunings (e.g., tenor bass).
Virtual drums are a type of audio software that simulates the sound of a drum kit using synthesized drum kit sounds or digital samples of acoustic drum sounds. Different drum software products offer a recording function, the ability to select from several acoustically distinctive drum kits (e.g., jazz, rock, metal), as well as the option to incorporate different songs into the session. Some software for the personal computer (PC) can turn any hard surface into a virtual drum kit using only one microphone.
Bassists trying to emulate the sound of a double bass sometimes pluck the strings with their thumb and use palm-muting to create a short, "thumpy" tone. Monk Montgomery (who played in Lionel Hampton's big band) and Bruce Palmer (who performed with Buffalo Springfield) use thumb downstrokes. The use of the thumb was acknowledged by early Fender models, which came with a "thumbrest" or "Tug Bar" attached to the pickguard below the strings. Contrary to its name, this was not used to rest the thumb, but to provide leverage while using the thumb to pluck the strings. The thumbrest was moved above the strings in 1970s models (as a true thumbrest) and eliminated in the 1980s. Nevertheless, some reissued versions of vintage Fender basses in the 2010s do include a thumbrest.
The shell almost invariably has a circular opening over which the drumhead is stretched, but the shape of the remainder of the shell varies widely. In the western musical tradition, the most usual shape is a cylinder, although timpani, for example, use bowl-shaped shells. Other shapes include a frame design (tar, Bodhrán), truncated cones (bongo drums, Ashiko), goblet shaped (djembe), and joined truncated cones (talking drum).
With the explosion of the popularity of rock music in the 1960s, many more manufacturers began making electric basses, including the Japanese manufacturers Yamaha, Teisco and Guyatone. First introduced in 1960, the Fender Jazz Bass was known as the Deluxe Bass and was meant to accompany the Jazzmaster guitar. The Jazz Bass (often referred to as a "J-bass") featured two single-coil pickups, one close to the bridge and one in the Precision bass' split coil pickup position. The earliest production basses had a 'stacked' volume and tone control for each pickup. This was soon changed to the familiar configuration of a volume control for each pickup, and a single, passive tone control. The Jazz Bass' neck was narrower at the nut than the Precision bass — 1 1⁄2 inches (38 mm) versus 1 3⁄4 inches (44 mm) — allowing for easier access to the lower strings and an overall spacing and feel closer to that of an electric guitar, allowing trained guitarists to transition to the bass guitar more easily.
The sound of electronic drums and cymbals themselves is heard by the drummer and possibly other musicians in close proximity, but even so, the foldback (audio monitor) system is usually fed from the electronic sounds rather than the live acoustic sounds. The drums can be heavily dampened (made to resonate less or subdue the sound), and their tuning and even quality is less critical in the latter scenario. In this way, much of the atmosphere of the live performance is retained in a large venue, but without some of the problems associated with purely microphone-amplified drums. Triggers and sensors can also be used in conjunction with conventional or built-in microphones. If some components of a kit prove more difficult to "mike" than others (e.g., an excessively "boomy" low tom), triggers may be used on only the more difficult instruments, balancing out a drummer's/band's sound in the mix.
The long scale necks on Leo Fender's basses—with a scale length (distance between nut and bridge) of 34 inches (864 mm) — set the standard for electric basses, although 30-inch (762 mm) "short scale" instruments, such as the Höfner 500/1 "violin bass" played by Paul McCartney, and the Fender Mustang Bass are also common. Short scale instruments use the same E-A-D-G tuning as a regular long scale instrument. Short scale instruments are good choices for bassists with smaller hands, such as children or young teens who are just starting the instrument. While 35-inch (889 mm), 35 1⁄2-inch (902 mm), and 36-inch (914 mm) scale lengths were once only available in "boutique" instruments, in the 2000s (decade), many manufacturers began offering these "extra long" scale lengths. This extra long scale provides a higher string tension, which may yield a more defined, deep tone on the low "B" string of five- and six-stringed instruments (or detuned four-string basses).
Snare drum and tom-tom Typical ways to muffle a snare or tom include placing an object on the outer edge of the drumhead. A piece of cloth, a wallet, gel, or fitted rings made of mylar are common objects. Also used are external clip-on muffles that work using the same principle. Internal mufflers that lie on the inside of the drumhead are often built into a drum, but are generally considered less effective than external muffles, as they stifle the initial tone, rather than simply reducing the sustain of it.
