Most basses have a volume potentiometer ("pot" or "knob"), which can be turned up or down, and a tone potentiometer, which rolls off the high frequencies when it is turned to the player's right. Some basses may also have a pickup selector control or switch, to select single-coil or humbucking pickups. Since the 1980s, basses are often available with battery-powered "active" electronics that boost the signal with a preamplifier and provide equalization controls to boost or cut bass and treble frequencies, or both. Some expensive basses have even more equalization options, such as bass, middle and treble.
A digital piano is a type of electronic keyboard designed to serve primarily as an alternative to the traditional piano, both in the way it feels to play and in the sound produced. It is intended to provide an accurate simulation of an acoustic piano. Some digital pianos are also designed to look like an ordinary piano, both the upright or grand piano. Digital pianos use either a synthesized emulation or samples of an actual piano, which are then amplified through an internal loudspeaker. Digital pianos incorporate weighted keys, which recreate the feel of an acoustic piano.
Many drummers extend their kits from this basic configuration, adding more drums, more cymbals, and many other instruments including pitched percussion. In some styles of music, particular extensions are normal. For example, rock and heavy metal drummers make use of double bass drums, which can be achieved with either a second bass drum or a remote double foot pedal. Some progressive drummers may include orchestral percussion such as gongs and tubular bells in their rig. Some performers, such as some rockabilly drummers, play small kits that omit elements from the basic setup. Some drum kit players may have other roles in the band, such as providing backup vocals, or less commonly, lead vocals.
Trigger pads and drums, on the other hand, when deployed in a conventional set-up, are most commonly used to produce sounds not possible with an acoustic kit, or at least not with what is available. Any sound that can be sampled/recorded can be played when the pad is struck, by assigning the recorded sounds to specific triggers . Recordings or samples of barking dogs, sirens, breaking glass and stereo recordings of aircraft taking off and landing have all been used. Along with the more obvious electronically generated sounds there are synthesized human voices or song parts or even movie audio or digital video/pictures that (depending on device used) can also be played/triggered by electronic drums.
William F. Ludwig, Sr., and his brother, Theobald Ludwig, founded the Ludwig & Ludwig Co. in 1909 and patented the first commercially successful bass drum pedal system, paving the way for the modern drum kit. It was the golden age of drum building for many famous drum companies, with Ludwig introducing... "The ornately engraved" Black Beauty Brass Snare drum; Slingerland premiered its Radio King solid-maple shell; Leedy invented the floating drum head & self-aligning lug;& Gretsch originated the three-way tension system of the Gladstone snare drum". Wire brushes for use with drums and cymbals were introduced in 1912. The need for brushes arose due to the problem of the drum sound overshadowing the other instruments on stage. Drummers began using metal fly swatters to reduce the volume on stage next to the other acoustic instruments. Drummers could still play the rudimentary snare figures and grooves with brushes that they would normally play with drumsticks.
The five-piece kit is the full entry-level kit and the most common configuration. It adds a third tom to the bass drum/snare drum/two toms set, making three toms in all. A fusion kit will normally add a 14" tom, either a floor tom or a hanging tom on a stand to the right of the bass drum; in either case, making the tom lineup 10", 12" and 14". Having three toms enables drummers to have a low-pitched, middle-register and higher-pitched tom, which gives them more options for fills and solos.
A fill is a departure from the repetitive rhythm pattern in a song. A drum fill is used to "fill in" the space between the end of one verse and the beginning of another verse or chorus. Fills vary from a simple few strokes on a tom or snare, to a distinctive rhythm played on the hi-hat, to sequences several bars long that are short virtuosic drum solos. As well as adding interest and variation to the music, fills serve an important function in preparing and indicating significant changes of sections in songs and linking sections. A vocal cue is a short drum fill that introduces a vocal entry. A fill ending with a cymbal crash on beat one is often used to lead into a chorus or verse.
On the topic of performing: is it the stage you have your sights on? In that case, set your sights on stage pianos, like the Roland RD-300NX for example. Powered by Roland's proprietary "SuperNATURAL" sound engine, it's so true-to-life that an audience just might find themselves wondering where you've hidden the baby grand. Another great suggestion is the Nord Stage 2 88-Key Stage Keyboard, which uses three sound-generating sections working together to provide outstanding versatility.
