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.
By World War I, drum kits were often marching band-style military bass drums with many percussion items suspended on and around them. Drum kits became a central part of jazz music, especially Dixieland. The modern drum kit was developed in the Vaudeville era during the 1920s in New Orleans. In 1917, a New Orleans band called "The Original Dixieland Jazz Band " recorded jazz tunes that became hits all over the country. These were the first official jazz recordings. Drummers such as Baby Dodds, "Zutty" Singleton and Ray Bauduc had taken the idea of marching rhythms, combining the bass drum and snare drum and "traps", a term used to refer to the percussion instruments associated with immigrant groups, which included miniature cymbals, tom toms, cowbells and woodblocks. They started incorporating these elements with ragtime, which had been popular for a couple of decades, creating an approach which evolved into a jazz drumming style.
In some styles of music, drummers use electronic effects on drums, such as individual noise gates that mute the attached microphone when the signal is below a threshold volume. This allows the sound engineer to use a higher overall volume for the drum kit by reducing the number of "active" mics which could produce unwanted feedback at any one time. When a drum kit is entirely miked and amplified through the sound reinforcement system, the drummer or the sound engineer can add other electronic effects to the drum sound, such as reverb or digital delay.
Electronic drum sets provide a great way to practice without rattling the whole house. These sets provide volume control so you won’t wake up the neighbors, but you can also plug in headphones to achieve a very quiet percussion session. That way only you will feel the noise. Electronic drums make ideal beginning sets, so students who are a little shy to practice out loud can just play to themselves. An extra benefit of electric drum sets is that some come equipped with built-in metronomes to keep you on time.
The PX-160 comes with the square SP-3 damper (sustain) pedal. It does the job but is far from an authentic piano experience. There are other piano-style pedals available, such as the M-Audio SP-2, that are nicer to play and don’t slide around as much. Casio offers the optional SP-33 pedal unit, which has a three-pedal configuration with separate soft, sostenuto, and sustain pedals—the traditional three-pedal setup found on most pianos. In duet play mode, the left and right pedals serve as damper pedals for their respective sides of the keyboard. The downside of the SP-33 is that it can be used only with Casio’s CS-67 stand (the two are also available together as a package).
Just like the acoustic instruments they're derived from, digital pianos come in different sizes. They also offer dozens of options for your perusal, so you can weigh all kinds of factors to find the right model for you. For instance, if you're looking to pack a lot of piano into as small a space as possible, consider instruments such as the Williams Allegro 88-Key Digital Piano or the Casio CDP-120. These are fairly compact pianos, but that doesn't limit the breadth of their samples and sound settings.
