One of the main things to consider when looking at a 4-string bass (and every bass for that matter) is the material used to make its body. Bass guitars are traditionally made of different varieties of wood and feature a solid, hard-bodied design. Alder is a favorite amongst musicians because it produces a clear, full-bodied sound. For warmer, smoother tones, a mahogany bass might be the one for you. Another aspect to look into is a fretted or fretless electric bass guitar. On a fretted bass, the frets divide the fingerboard into semi tone divisions. These models make learning the bass easier because you have a guide for finger placement. Fretless basses offer a different sound because without frets the strings are directly pressed into the wood of the neck. This produces a softer sound because the string is in direct contact with the musician's finger and also allows you to slide up and down the neck with ease. The electric bass guitar is said to be the cornerstone of the band. It establishes the beat and brings a booming, punchy sound to the music. From Flea of the Red Hot Chili Peppers to Paul McCartney of the Beatles, musicians have been playing the bass for decades in modern, mainstream music groups. No matter what skill level you're at right now, these is certainly an electric bass guitar that will meet and exceed all your sound and style needs.
Chords are not used that often by electric bass players. However, in some styles, bassists may sound "double stops", such as octaves with open strings and powerchords. In Latin music, double stops with fifths are used. Robert Trujillo of Metallica is known for playing "massive chords"  and "chord-based harmonics"  on the bass. Lemmy of Motörhead often played power chords in his bass lines.
In "miking" a drum kit, dynamic microphones, which can handle high sound-pressure levels, are usually used to close-mic drums, which is the predominant way to mic drums for live shows. Condenser microphones are used for overheads and room mics, an approach which is more common with sound recording applications. Close miking of drums may be done using stands or by mounting the microphones on the rims of the drums, or even using microphones built into the drum itself, which eliminates the need for stands for these microphones, reducing both clutter and set-up time, as well as isolating them.
Bass solos are performed using a range of different techniques, such as plucking or fingerpicking. In the 1960s, The Who's bassist, John Entwistle, performed a bass break on the song "My Generation" using a plectrum. He originally intended to use his fingers, but could not put his plectrum down quickly enough. This is considered as one of the first bass solos in rock music, and also one of the most recognizable. Led Zeppelin's "Good Times Bad Times", the first song on their first album, contains two brief bass solos, occurring after the song's first and third choruses. Queen's bassist, John Deacon, occasionally played bass solos, such as on the song "Liar". Metallica's 1983 debut Kill Em All includes the song "(Anesthesia) Pulling Teeth," consisting entirely of a bass solo played by Cliff Burton.
The fretting hand—the left hand for right-handed bass players and right hand for left-handed bass players—presses down the strings to play different notes and shape the tone or timbre of a plucked or picked note. One fretting technique is a finger per fret, where each finger in the fretting hand plays one fret in a given position, giving the advantage that full chromatic scale of over an octave and a half can be played with no up-down wrist movement. Also, the double bass-style technique can be used for fretting. This technique involves using four fingers in the space of three frets, especially in the lower positions (i.e., the fretting positions closer to the nut, where the space between notes is the widest). When considering the spacing between notes, this is a comfortable distance for the average person's hand size, however it requires more up-down hand movements. The main advantage of the "four fingers in three frets technique is less tendon strain, leading to a diminished likelihood of Repetitive Strain Injury (RSI). The image below (of a bassist performing tapping) shows the four-in-three.
1956 saw the appearance at the German trade fair "Musikmesse Frankfurt" of the distinctive Höfner 500/1 violin bass made using violin construction techniques by Walter Höfner, a second generation violin luthier. The instrument is often known as the "Beatle Bass", due to its endorsement and use by Beatles bassist Paul McCartney. In 1957 Rickenbacker introduced the model 4000 bass, the first bass to feature a neck-through-body design in which the neck is part of the body wood. The Fender and Gibson versions used bolt-on and glued-on necks.
"Precision" pickups (which refers to the Fender Precision Bass), also referred to as "P pickups", are two distinct single-coil pickups. Each is offset a small amount along the length of the body so that each half is underneath two strings. The pickups are reverse-wound with reversed magnetic polarity to reduce unwanted hum. This makes the 'P' pickup a humbucking single coil pickup. Less common is the "single-coil P" pickup, used on the original 1951 Fender Precision bass. P-style pickups are generally placed in the "neck" or "middle" position, but some luthiers and performers have used P pickups in the bridge position, or in between two jazz pickups.
Although there are far fewer university programs that offer electric bass instruction in jazz and popular music, some universities offer bachelor's degrees (B.Mus.) and Master of Music (M.Mus.) degrees in jazz performance or "commercial music", where electric bass can be the main instrument. In the US, the Manhattan School of Music has a jazz program leading to B.Mus. and M.Mus degrees that accepts students who play bass (double bass and electric bass), guitar, piano, drums, and melody instruments (e.g., saxophone, trumpet, etc.).
Bass guitars require a bass amp. It is possible to play a guitar through a bass amp, but you cannot play a bass through a guitar amp without damaging the amp. Amplifying low-frequency sounds is more challenging and requires both different equipment and more space compared to an ordinary guitar's amplification needs. Like guitar amps, bass amps can be combined or separated into the head and the speaker.
In the mid-1970s, Alembic and other boutique bass manufacturers, such as Tobias, produced four-string and five-string basses with a low "B" string. In 1975, bassist Anthony Jackson commissioned luthier Carl Thompson to build a six-string bass tuned (low to high) B0, E1, A1, D2, G2, C3. In comparison with a standard four-string bass, Jackson's six-string adds a low B string and a high C string. These 5 and 6-string "extended-range basses" would become popular with session bassists as they reduced the need for re-tuning to alternate detuned configurations like "drop D", and also allowed the bassist to play more notes from the same position on the fretboard with fewer shifts up and down the fingerboard, a crucial benefit for a session player sightreading basslines at a recording session.
In some cases, to play the bass through PA amplification, it is plugged into a direct box or DI, which routes the signal to the bass amp while also sending the signal directly into a mixing console, and thence to the main and monitor speakers. When a recording of bass is being made, engineers may use a microphone set up in front of the amplifier's speaker cabinet for the amplified signal, a direct box signal that feeds the recording console, or a mix of both.
Types of bass lines vary widely, depending on musical style. However, the bass guitarist generally fulfills a similar role: anchoring the harmonic framework (often by emphasizing the roots of the chord progression) and laying down the beat in collaboration with the drummer and other rhythm section instruments. The importance of the bass guitarist and the bass line varies in different styles of music. In some pop styles, such as 1980s-era pop and musical theater, the bass sometimes plays a relatively simple part as the music emphasizes vocals and melody instruments. In contrast, in reggae, funk, or hip-hop, entire songs may center on the bass groove, and the bass line is usually prominent in the mix.
A drum solo is an instrumental section that highlights the virtuosity, skill and musical creativity of the drummer. While other instrument solos such as guitar solos are typically accompanied by the other rhythm section instruments (e.g., bass guitar and electric guitar), for most drum solos, all the other band members stop playing so that all of the audience's focus will be on the drummer. In some drum solos, the other rhythm section instrumentalists may play "punches" at certain points–sudden, loud chords of a short duration. Drum solos are common in jazz, but they are also used in a number of rock genres, such as heavy metal and progressive rock. During drum solos, drummers have a great deal of creative freedom, and drummers often use the entire drum kit. In live concerts, drummers may be given long drum solos, even in genres where drum solos are rare on singles.
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.
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.
