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.
Chinese troops used tàigǔ drums to motivate troops, to help set a marching pace, and to call out orders or announcements. For example, during a war between Qi and Lu in 684 BC, the effect of drum on soldier's morale is employed to change the result of a major battle. Fife-and-drum corps of Swiss mercenary foot soldiers also used drums. They used an early version of the snare drum carried over the player's right shoulder, suspended by a strap (typically played with one hand using traditional grip). It is to this instrument that the English word "drum" was first used. Similarly, during the English Civil War rope-tension drums would be carried by junior officers as a means to relay commands from senior officers over the noise of battle. These were also hung over the shoulder of the drummer and typically played with two drum sticks. Different regiments and companies would have distinctive and unique drum beats only they recognized. In the mid-19th century, the Scottish military started incorporating pipe bands into their Highland Regiments.
Electronic drums are used for many reasons. Some drummers use electronic drums for playing in small venues such as coffeehouses or church services, where a very low volume for the band is desired. Since fully electronic drums do not create any acoustic sound (apart from the quiet sound of the stick hitting the sensor pads), all of the drum sounds come from a keyboard amplifier or PA system; as such, the volume of electronic drums can be much lower than an acoustic kit. Some drummers use electronic drums as practice instruments, because they can be listened to with headphones, enabling a drummer to practice in an apartment or in the middle of the night without disturbing others. Some drummers use electronic drums to take advantage of the huge range of sounds that modern drum modules can produce, which range from sampled sounds of real drums, cymbals and percussion instruments (including instruments that would be impractical to take to a small gig, such as gongs or tubular bells), to electronic and synthesized sounds, including non-instrument sounds such as ocean waves.
The keyboard action of an acoustic grand piano is composed of black and white keys, graded hammers, and numerous other components working in harmony when each note is pressed. This beautifully designed mechanism allows gifted pianists to express a wealth of feeling and emotion in their music, as they appreciate and respond to the tactile nuances transmitted through the keyboard.
While fretless basses are often associated with jazz and jazz fusion, bassists from other genres have used fretless basses, such as Freebo (country), Rick Danko (rock/blues), Rod Clements (folk), Steve DiGiorgio, Jeroen Paul Thesseling (metal), Tony Franklin (rock), and Colin Edwin (modern/progressive rock). Some bassists alternate between fretted and fretless basses in performances, according to the type of material or tunes they are performing, e.g., Pino Palladino or Tony Levin.
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.
In the 2010s, some drummers use a variety of auxiliary percussion instruments, found objects, and electronics as part of their "drum" kits. Popular electronics include: electronic sound modules; laptop computers used to activate loops, sequences and samples; metronomes and tempo meters; recording devices; and personal sound reinforcement equipment (e.g., a small PA system to amplify electronic drums and provide a monitor).
Drummers use a variety of accessories when practicing. Metronomes and beat counters are used to develop a sense of a steady pulse. Drum muffling pads may be used to lessen the volume of drums during practicing. A practice pad, held on the lap, on a leg, or mounted on a stand, is used for near-silent practice with drumsticks. A set of practice pads mounted to simulate an entire drum kit is known as a practice kit. In the 2010s, these have largely been superseded by electronic drums, which can be listened to with headphones for quiet practice and kits with non-sounding mesh heads.
