Digital pianos and keyboards are designed to accomplish very different things. Digital pianos, as the name suggests, are intended simply to be a digital replication of an acoustic or grand piano. Digital pianos have weighted keys so that the experience of playing one more closely resembles a traditional piano. Digital pianos are ideal for those who want to learn to play the piano but don’t want to pay the incredibly high cost of purchasing one or deal with the hassle of finding space for one. After all, there’s almost nothing cheap, easy, or convenient about buying or owning a traditional piano. Digital pianos have been designed to mitigate these factors by being less expensive, easier to maintain, and much easier to transport. Digital pianos are also beneficial for more advanced musicians that want to record their music onto a computer.
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.
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 In the 2010s, these have largely been superseded by electronic drums, which can be listened to with headphones for quiet practice and kits with non-sounding mesh heads.
In most implementations, a digital piano produces a variety of piano timbres and usually other sounds as well. For example, a digital piano may have settings for a concert grand piano, an upright piano, a tack piano, and various electric pianos such as the Fender Rhodes, the Wurlitzer, and the DX electric piano. Some digital pianos incorporate other basic "synthesizer" sounds such as string ensemble, for example, and offer settings to combine them with piano.
A four-piece kit extends the three-piece by adding one tom, either a second hanging tom mounted on the bass drum (a notable user is Chris Frantz of Talking Heads) and often displacing the cymbal, or by adding a floor tom. Normally another cymbal is added as well, so there are separate ride and crash cymbals, either on two stands, or the ride cymbal mounted on the bass drum to the player's right and the crash cymbal on a separate stand. The standard cymbal sizes are 16" crash and 18"–20" ride, with the 20" ride most common.
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.
Snare drum and tom-tom Typical ways to muffle a snare or tom include placing an object on the outer edge of the drumhead. A piece of cloth, a wallet, gel, or fitted rings made of mylar are common objects. Also used are external clip-on muffles that work using the same principle. Internal mufflers that lie on the inside of the drumhead are often built into a drum, but are generally considered less effective than external muffles, as they stifle the initial tone, rather than simply reducing the sustain of it.
The drum is a member of the percussion group of musical instruments. In the Hornbostel-Sachs classification system, it is a membranophone. Drums consist of at least one membrane, called a drumhead or drum skin, that is stretched over a shell and struck, either directly with the player's hands, or with a percussion mallet, to produce sound. There is usually a resonance head on the underside of the drum, typically tuned to a slightly lower pitch than the top drumhead. Other techniques have been used to cause drums to make sound, such as the thumb roll. Drums are the world's oldest and most ubiquitous musical instruments, and the basic design has remained virtually unchanged for thousands of years.
Prior to the development of the drum set, drums and cymbals used in military and orchestral music settings were played separately by different percussionists; if the score called for bass drum, triangle and cymbals, three percussionists would be hired to play these three instruments. In the 1840s, percussionists began to experiment with foot pedals as a way to enable them to play more than one instrument, but these devices would not be mass-produced for another 75 years. By the 1860s, percussionists started combining multiple drums into a set. The bass drum, snare drum, cymbals, and other percussion instruments were all struck with hand-held drum sticks. Drummers in musical theater shows and stage shows, where the budget for pit orchestras was often limited, contributed to the creation of the drum set by developing techniques and devices that would enable them to cover the roles of multiple percussionists.
There are a range of different string types including all-metal strings, which are available in many varieties of winding or finishing, each of which produce different tone, including roundwound, flatwound, halfwound, ground wound, and pressure wound); as well as metal strings with different coverings, such as tapewound and wound with plastic coatings. The variety of materials used in the strings gives bass players a range of tonal options. In the 1950s and early 1960s, bassists mostly used flatwound strings with a smooth surface, which had a smooth, damped sound reminiscent of a double bass. In the late 1960s and 1970s, players began using roundwound bass strings, which produce a brighter tone similar to steel guitar strings, though flatwounds also remained in use by players seeking a vintage tone. Roundwounds have a brighter timbre (tone) with longer sustain than flatwounds.
Most drummers have a single main ride, located near their right hand—within easy playing reach, as it is used very regularly—most often a 20" sizing but, 16"-24" diameters are not uncommon. It is most often a heavy, or medium-weighted cymbal that cuts through other instrumental sounds, but some drummers use a swish cymbal, sizzle cymbal or other exotic or lighter metal ride, as the main or only ride in their kit, particularly for jazz, gospel or ballad/folk sounds. In the 1960s Ringo Starr used a sizzle cymbal as a second ride, particularly during guitar solos.
