A drum kit – also called a drum set, trap set or simply drums – is a collection of drums, cymbals and other percussion instruments, which are set up on stands to be played by a single player, with drumsticks held in both hands and the feet operating pedals that control the hi-hat cymbal and the beater for the bass drum. Sometimes, there may be two bass drum pedals to create a faster rhythm. A drum kit consists of a mix of drums and idiophones – most significantly cymbals, but can also include the woodblock and cowbell. In the 2020s, some kits also include electronic instruments. Also, both hybrid and entirely electronic kits are used.
An effects unit or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing.
The bass drum, or kick drum, is a large drum that produces a note of low definite or indefinite pitch. The instrument is typically cylindrical, with the drum's diameter much greater than the drum's depth, with a struck head at both ends of the cylinder. The heads may be made of calfskin or plastic and there is normally a means of adjusting the tension either by threaded taps or by strings. Bass drums are built in a variety of sizes, but size does not dictate the volume produced by the drum. The pitch and the sound can vary much with different sizes, but the size is also chosen based on convenience and aesthetics. Bass drums are percussion instruments and vary in size and are used in several musical genres. Three major types of bass drums can be distinguished.
A subwoofer is a loudspeaker designed to reproduce low-pitched audio frequencies known as bass and sub-bass, lower in frequency than those which can be (optimally) generated by a woofer. The typical frequency range for a subwoofer is about 20–200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-certified systems. Subwoofers are never used alone, as they are intended to augment the low-frequency range of loudspeakers that cover the higher frequency bands. While the term "subwoofer" technically only refers to the speaker driver, in common parlance, the term often refers to a subwoofer driver mounted in a speaker enclosure (cabinet), often with a built-in amplifier.
The Leslie speaker is a combined amplifier and loudspeaker that projects the signal from an electric or electronic instrument and modifies the sound by rotating a baffle chamber ("drum") in front of the loudspeakers. A similar effect is provided by a rotating system of horns in front of the treble driver. It is most commonly associated with the Hammond organ, though it was later used for the electric guitar and other instruments. A typical Leslie speaker contains an amplifier, a treble horn and a bass speaker—though specific components depend upon the model. A musician controls the Leslie speaker by either an external switch or pedal that alternates between a slow and fast speed setting, known as "chorale" and "tremolo".
An instrument amplifier is an electronic device that converts the often barely audible or purely electronic signal of a musical instrument into a larger electronic signal to feed to a loudspeaker. An instrument amplifier is used with musical instruments such as an electric guitar, an electric bass, electric organ, synthesizers and drum machine to convert the signal from the pickup or other sound source into an electronic signal that has enough power, due to being routed through a power amplifier, capable of driving one or more loudspeaker that can be heard by the performers and audience.
A guitar amplifier is an electronic device or system that strengthens the weak electrical signal from a pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden cabinet. A guitar amplifier may be a standalone wood or metal cabinet that contains only the power amplifier circuits, requiring the use of a separate speaker cabinet–or it may be a "combo" amplifier, which contains both the amplifier and one or more speakers in a wooden cabinet. There is a wide range of sizes and power ratings for guitar amplifiers, from small, lightweight "practice amplifiers" with a single 6" speaker and a 10 watt amp to heavy combo amps with four 10” or four 12" speakers and a powerful 100 watt amplifier, which are loud enough to use in a nightclub or bar performance.
A DI unit is an electronic device typically used in recording studios and in sound reinforcement systems to connect a high-output impedance, line level, unbalanced output signal to a low-impedance, microphone level, balanced input, usually via an XLR connector and XLR cable. DIs are frequently used to connect an electric guitar or electric bass to a mixing console's microphone input jack. The DI performs level matching, balancing, and either active buffering or passive impedance matching/impedance bridging to minimize unwanted noise, distortion, and ground loops. DI units are typically metal boxes with input and output jacks and, for more expensive units, “ground lift” and attenuator switches.
GarageBand is a line of digital audio workstations for macOS, iPadOS, and iOS devices that allows users to create music or podcasts. GarageBand is developed by Apple for macOS, and was once part of the iLife software suite, along with iMovie and iDVD. Its music and podcast creation system enables users to create multiple tracks with pre-made MIDI keyboards, pre-made loops, an array of various instrumental effects, and voice recordings.
A cajón is a box-shaped percussion instrument originally from Peru, played by slapping the front or rear faces with the hands, fingers, or sometimes implements such as brushes, mallets, or sticks. Cajones are primarily played in Afro-Peruvian music, but has made its way into flamenco as well. The term cajón is also applied to other box drums used in Latin American music, such as the Cuban cajón de rumba and the Mexican cajón de tapeo.
A noise gate or gate is an electronic device or software that is used to control the volume of an audio signal. Comparable to a compressor, which attenuates signals above a threshold, such as loud attacks from the start of musical notes, noise gates attenuate signals that register below the threshold. However, noise gates attenuate signals by a fixed amount, known as the range. In its simplest form, a noise gate allows a main signal to pass through only when it is above a set threshold: the gate is "open". If the signal falls below the threshold, no signal is allowed to pass : the gate is "closed". A noise gate is used when the level of the "signal" is above the level of the unwanted "noise". The threshold is set above the level of the "noise", and so when there is no main "signal", the gate is closed.
The electric upright bass (EUB) is an instrument that can perform the musical function of a double bass. It requires only a minimal or 'skeleton' body to produce sound because it uses a pickup and electronic amplifier and loudspeaker. Therefore, a large resonating structure is not required to project the sound into the air. This minimal body greatly reduces the bulk and weight of the instrument. EUBs must always be connected to an amplifier and speaker cabinet to produce an adequate audible sound. The EUB retains enough of the features of the double bass so that double bass players are able to perform on it.
A one-man band is a musician who plays a number of instruments simultaneously using their hands, feet, limbs, and various mechanical or electronic contraptions. One-man bands also often sing while they perform.
Electro-Harmonix is a New York City-based company that makes electronic audio processors and sells rebranded vacuum tubes. The company was founded by Mike Matthews in 1968. It is best known for a series of guitar effects pedals introduced in the 1970s and 1990s. EHX also made a line of guitars in the 70s.
An acoustic-electric guitar is an acoustic guitar fitted with a microphone or a magnetic or piezoelectric pickup. They are used in a variety of music genres where the sound of an acoustic guitar is desired but more volume is required, especially during live performances. The design is distinct from a semi-acoustic guitar, which is an electric guitar with the addition of sound chambers within the guitar body.
An experimental musical instrument is a musical instrument that modifies or extends an existing instrument or class of instruments, or defines or creates a new class of instrument. Some are created through simple modifications, such as cracked drum cymbals or metal objects inserted between piano strings in a prepared piano. Some experimental instruments are created from household items like a homemade mute for brass instruments such as bathtub plugs. Other experimental instruments are created from electronic spare parts, or by mixing acoustic instruments with electric components.
Steven Gene Wold, commonly known as Seasick Steve, is an American blues musician. He plays mostly personalized guitars and sings, usually about his early life doing casual work. From the late 1960s, he worked as a musician and recording engineer in the US and Europe; he played bass in Shanti, was in a disco band called Crystal Grass as well as other bands. He also pursued other works, including producing an album for Modest Mouse. He achieved his breakthrough, initially in the UK, at the end of 2006 when he appeared on Jools Holland's annual Hootenanny as Seasick Steve. He has since released a number of commercially successful albums, including I Started Out with Nothin and I Still Got Most of It Left, Man from Another Time, and Sonic Soul Surfer.
Bass effects are electronic effects units that are designed for use with an electric bass and a bass amplifier, or for an upright bass and a bass amp or PA system. Bass effects are commonly available in stompbox-style pedals, which are metal or plastic boxes with a foot-operated pedal switch or button which turns the effect on and off. Most pedals also have knobs to control the tone, volume and effect level. Some bass effects are available in 19" rackmount units, which can be mounted in a road case. As well, some bass amplifiers have built-in effects, such as overdrive or chorus.
Live sound mixing is the blending of multiple sound sources by an audio engineer using a mixing console or software. Sounds that are mixed include those from instruments and voices which are picked up by microphones and pre-recorded material, such as songs on CD or a digital audio player. Individual sources are typically equalised to adjust the bass and treble response and routed to effect processors to ultimately be amplified and reproduced via a loudspeaker system. The live sound engineer listens and balances the various audio sources in a way that best suits the needs of the event.
The BeatBuddy is a digital drum machine made by Singular Sound which is housed in the form of a stompbox unit. The floor-based format and pedal footswitch enables musicians to control the device "hands-free" while they are performing an instrument with their hands.
