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.
While digital pianos may sometimes fall short of a real piano in feel and sound, they nevertheless have other advantages over acoustic pianos. Digital pianos cost much less than an acoustic piano and most models are much smaller and lighter in weight than an acoustic piano. In addition, digital pianos do not need to be tuned, and their tuning can be modified to match the tuning of another instrument (e.g., a pipe organ). Like other electronic musical instruments, digital pianos can be connected to a keyboard amplifier or a PA system to produce a sound loud enough for a large venue. Some digital pianos can also emulate other sounds besides the piano, the most common ones being pipe organ, electric piano, Hammond organ and harpsichord. Digital pianos are often used in music schools and music studios to replace traditional instruments.
A common feature of more expensive basses is "neck-through" construction. Instead of milling the body from a single piece of wood (or "bookmatched" halves) and then attaching the neck into a pocket (so-called "bolt-on" design), neck-through basses are constructed first by assembling the neck, which may comprise one, three, five or more layers of wood in vertical stripes, which are longer than the length of the fretboard. To this elongated neck, the body is attached as two wings, which may also be made up of several layers. The entire bass is then milled and shaped. Neck-through construction advertisements claim this approach provides better sustain and a mellower tone than bolt-on neck construction. While neck-through construction is most common in handmade "boutique" basses, some models of mass-produced basses such as Ibanez's BTB series also have neck-through construction. Bolt-on neck construction does not necessarily imply a cheaply made instrument; virtually all traditional Fender designs still use bolt-on necks, including its high-end instruments costing thousands of dollars, and many boutique luthiers such as Sadowsky build bolt-on basses as well as neck-through instruments.
An uncommon form of digital piano that resemble a grand piano, usually with a more precision keyboard action and high-quality sound system built into the unit's cabinet in a similar manner as the strings on a grand piano. These pianos are mostly high-end novelty models offered by only small number of manufacturers, and often has higher prices than an average acoustic piano.
Percussion instruments are the most ancient instruments of all, and were present in the early tribal days of nearly every civilization. Drums today are an important part of human culture, not just because they speak to a variety of musical heritages, but because it’s said we all carry around a personal rhythm in our beating hearts. At Amazon.com, we honor one of the world’s oldest traditions by offering drums and percussion accessories for every level of player.
Although these kits may be small with respect to the number of drums used, the drums themselves are most often normal sizes, or even larger in the case of the bass drum. Kits using smaller drums in both smaller and larger configurations are also produced for particular uses, such as boutique kits designed to reduce the visual impact that a large kit creates or due space constraints in coffeehouses, travelling kits to reduce luggage volume, and junior kits for very young players. Smaller drums also tend to be quieter, again suiting smaller venues, and many of these kits extend this with extra muffling which allows quiet or even silent practice in a hotel room or bedroom.
Electronic drum pads are the second most widely used type of MIDI performance controllers, after electronic music keyboards.:319–320 Drum controllers may be built into drum machines, they may be standalone control surfaces (e.g., rubber drum pads), or they may emulate the look and feel of acoustic percussion instruments. The pads built into drum machines are typically too small and fragile to be played with sticks, and they are usually played with fingers.:88 Dedicated drum pads such as the Roland Octapad or the DrumKAT are playable with the hands or with sticks, and are often built to resemble the general form of a drum kit. There are also percussion controllers such as the vibraphone-style MalletKAT,:88–91 and Don Buchla's Marimba Lumina.
Specific bass brands/models became identified with particular styles of music, such as the Rickenbacker 4001 series, which became identified with progressive rock bassists like Chris Squire of Yes, and Geddy Lee of Rush, while the StingRay was used by funk/disco players such Louis Johnson of the funk band The Brothers Johnson and Bernard Edwards of Chic. The 4001 stereo bass was introduced in the late 1960s; it can be heard on the Beatles' "I Am The Walrus." 
Digital pianos typically use analog sensors for its keyboard action, as opposed to digital sensors of a regular keyboard and synthesizer. These sensors notably works in a similar way to those used in analog joysticks found on video game controllers, in which they the velocity input is converted from the key movement as well, not just the initial pressure of the key sensor.
1956 saw the appearance at the German trade fair "Musikmesse Frankfurt" of the distinctive Höfner 500/1 violin bass made using violin construction techniques by Walter Höfner, a second generation violin luthier. The instrument is often known as the "Beatle Bass", due to its endorsement and use by Beatles bassist Paul McCartney. In 1957 Rickenbacker introduced the model 4000 bass, the first bass to feature a neck-through-body design in which the neck is part of the body wood. The Fender and Gibson versions used bolt-on and glued-on necks.
Combining rich acoustic sound with modern music technology, digital pianos are sophisticated instruments that are played and favoured by professionals and amateur musicians around the world. More lightweight and affordable than full-size grand pianos, today's digital pianos sound so close to their classic counterparts that untrained ears would have a hard time telling the sound produced by the two apart! In this section you'll find a wide variety of home and stage digital pianos from all the big brands. Yamaha, Suzuki, Roland and more, they're all here, so if you're in the market for a digital piano that was designed to perform, you're definitely in the right spot.
