Like the electric guitar, the electric bass guitar is almost always connected to an amplifier and a speaker with a patch cord for live performances. Electric bassists use either a "combo" amplifier, which combines an amplifier and a speaker in a single cabinet, or an amplifier and one or more speaker cabinets (typically stacked, with the amplifier sitting on the speaker cabinets, leading to the term "half-stack" for one cabinet setups and "full stack" for two).
A trigger pad could contain up to four independent sensors, each of them capable of sending information describing the timing and dynamic intensity of a stroke to the drum module/brain. A circular drum pad may have only one sensor for triggering, but a 2016-era cymbal-shaped rubber pad/cymbal will often contain two; one for the body and one for the bell at the centre of the cymbal, and perhaps a cymbal choke trigger, to allow drummers to produce this effect.
Drummers using electronic drums, drum machines, or hybrid acoustic-electric kits (which blend traditional acoustic drums and cymbals with electronic pads) typically use a monitor speaker, keyboard amplifier or even a small PA system to hear the electronic drum sounds. Even a drummer playing entirely acoustic drums may use a monitor speaker to hear her drums, especially if she is playing in a loud rock or metal band, where there is substantial onstage volume from huge, powerful guitar stacks. Since the drum kit uses the deep bass drum, drummers are often given a large speaker cabinet with a 15" subwoofer to help them monitor their bass drum sound (along with a full-range monitor speaker to hear the rest of their kit). Some sound engineers and drummers prefer to use an electronic vibration system, colloquially known as a "butt shaker" or "throne thumper" to monitor the bass drum, because this lowers the stage volume. With a "butt shaker", the "thump" of each bass drum strike causes a vibration in the drum stool; this way the drummer feels their beat on the posterior, rather than hears it.
In 1971, Alembic established the template for what became known as "boutique" or "high-end" electric bass guitars. These expensive, custom-tailored instruments, as used by Phil Lesh, Jack Casady, and Stanley Clarke, featured unique designs, premium hand-finished wood bodies, and innovative construction techniques such as multi-laminate neck-through-body construction and graphite necks. Alembic also pioneered the use of onboard electronics for pre-amplification and equalization. Active electronics increase the output of the instrument, and allow more options for controlling tonal flexibility, giving the player the ability to amplify as well as to attenuate certain frequency ranges while improving the overall frequency response (including more low-register and high-register sounds). 1973 saw the UK company Wal begin production of a their own range of active basses, and In 1974 Music Man Instruments, founded by Tom Walker, Forrest White and Leo Fender, introduced the StingRay, the first widely produced bass with active (powered) electronics built into the instrument. Basses with active electronics can include a preamplifier and knobs for boosting and cutting the low and high frequencies.
Many basses have just one pickup, typically a "P" or "MM" pickup, though single soapbars are not unheard of. Multiple pickups are also quite common, two of the most common configurations being two "J" pickups (as on the stock Fender Jazz), or a "P" near the neck and a "J" near the bridge (e.g., Fender Precision Bass Special, Fender Precision Bass Plus). A two-"soapbar" configuration is also very common, especially on basses by makes such as Ibanez and Yamaha. A combination of a J or other single-coil pickup at the neck and a Music Man-style humbucker in the bridge has become popular among boutique instrument builders, giving a very bright, focused tone that is good for jazz, funk and thumbstyle.
Tapewound (double bass type) and flatwound strings are sometimes used with the fretless bass so the metal string windings do not wear down the fingerboard. Tapewound and flatwound strings have a distinctive tone and sound. Some fretless basses have epoxy-coated fingerboards, or fingerboards made of an epoxy composite like micarta, to increase the fingerboard's durability, enhance sustain, and give a brighter tone.
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.)
The keyboards all came in to our Los Angeles office. After unboxing them and setting them up, I invited Liz, Jack, and Brent to come in and try them out. I asked them to rate the key action and the sound of the piano and to evaluate features from the perspective of a beginner. After playing through all of them over a couple hours, we talked through the pros and cons of each keyboard, and they gave me their top three choices.
Regardless of the model or series, a bass typically has four strings. They are tuned the same way as the first four strings on a regular guitar: E, A, D, and G. Some musical genres have alternative tunings, though. For example, metal often uses "drop D" tuning, where the E on the lowest string is tuned down a step to D. Most alternative tunings involve tuning down. Some basses have a fifth string. Usually this is added to the low end, where it becomes a B in standard tuning. In rare cases. it will be added to the high end, where it is known as a tenor fifth string and becomes a C. In even rarer cases, a bass can have six strings, using both the low B and the high C. The neck of the bass can be comprised of woods that range from maple to rosewood.
The electric bass is a relative newcomer to the world of jazz. The big bands of the 1930s and 1940s Swing era and the small combos of the 1950s Bebop and Hard Bop movements all used the double bass. The electric bass was introduced in some bands in the 1950s and it became prominent during the late 1960s and early 1970s, when rock influences were blended with jazz to create jazz-rock fusion.
In most implementations, a digital piano produces a variety of piano timbres and usually other sounds as well. For example, a digital piano may have settings for a concert grand piano, an upright piano, a tack piano, and various electric pianos such as the Fender Rhodes, the Wurlitzer, and the DX electric piano. Some digital pianos incorporate other basic "synthesizer" sounds such as string ensemble, for example, and offer settings to combine them with piano.
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.
The hi-hat cymbals (nicknamed "hats") consist of two cymbals mounted facing each other on a metal pole with folding support legs that keep a hollow support cylinder standing up. Like the bass drum, the hi-hat has a foot pedal. The bottom cymbal is fixed in place. The top cymbal is mounted on a thin pole which is inserted into the hollow cymbal stand cylinder. The thin pole is connected to a foot pedal. When the foot pedal is pressed down, a mechanism causes the thin pole to move down, causing the cymbals to move together. When the foot is lifted off the pedal, the cymbals move apart, due to the pedal's spring-loaded mechanism. The hi-hats can be sounded by striking the cymbals with one or two sticks or just by opening and closing the cymbals with the footpedal, without striking the cymbals. The ability to create rhythms on the hi-hats with the foot alone enables drummers to use both sticks on other drums or cymbals. Different sounds can be created by striking "open hi-hats" (without the pedal depressed, which creates a noisy sound nicknamed "sloppy hats") or a crisp "closed hi-hats" sound (with the pedal pressed down). As well, the high hats can be played with a partially depressed pedal.
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.
Bass bodies are typically made of wood, although other materials such as graphite (for example, some of the Steinberger designs) and other lightweight composite materials have also been used. While a wide variety of woods are suitable for use in the body, neck, and fretboard of the bass guitar, the most common types of wood used are similar to those used for electric guitars; alder, ash or mahogany for the body, maple for the neck, and rosewood or ebony for the fretboard. While these traditional standards are most common, for tonal or aesthetic reasons luthiers more commonly experiment with different tonewoods on basses than with electric guitars (though this is changing), and rarer woods like walnut and figured maple, as well as exotic woods like bubinga, wenge, koa, and purpleheart, are often used as accent woods in the neck or on the face of mid- to high-priced production basses and on custom-made and boutique instruments.
Casio definitely thought about the student/teacher relationship when designing the PX-160. It has a duet play mode, which splits the keyboard into two halves. Each half is the same octave range (about three and a half octaves per side), so a teacher can demonstrate on one side while the student plays on the other at the same pitch. Two headphone jacks allow both players to use headphones without the need for a splitter. If the speakers are being used, they can also be configured to output sound from the left keyboard side to the left speaker and vice versa.
While digital pianos may sometimes fall short of a real piano in feel and sound, they nevertheless have other advantages over acoustic pianos. Digital pianos cost much less than an acoustic piano and most models are much smaller and lighter in weight than an acoustic piano. In addition, digital pianos do not need to be tuned, and their tuning can be modified to match the tuning of another instrument (e.g., a pipe organ). Like other electronic musical instruments, digital pianos can be connected to a keyboard amplifier or a PA system to produce a sound loud enough for a large venue. Some digital pianos can also emulate other sounds besides the piano, the most common ones being pipe organ, electric piano, Hammond organ and harpsichord. Digital pianos are often used in music schools and music studios to replace traditional instruments.
