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.
In addition to pressing down one note at a time, bassists can also press down several notes at one time with their fretting hand to perform a double stop (two notes at once) or a chord. While double stops and chords are used less often by bassists than by electric guitarists playing rhythm guitar, a variety of double stops and chords can be performed on the electric bass. Some double stops used by bassists include octaves. Chords can be especially with effective on instruments with higher ranges such as six-string basses. Another variation to fully pressing down a string is to gently graze the string with the finger at the harmonic node points on the string, which creates chime-like upper partials (also called "overtones"). Glissando is an effect in which the fretting hand slides up or down the neck, which can be used to create a slide in pitch up or down. A subtle glissando can be performed by moving the fretting hand without plucking or picking the string; for a more pronounced effect, the string is plucked or picked first, or, in a metal or hardcore punk context, a pick may be scraped along the sides of the lower strings.
Of all of the genres, jazz and the mainstream commercial genres (rock, R&B, etc.) have the most established and comprehensive systems of instruction and training for electric bass. In the jazz scene, teens can begin taking private lessons on the instrument and performing in amateur big bands at high schools or run by the community. Young adults who aspire to be come professional jazz bassists or studio rock bassists can continue their studies in a variety of formal training settings, including colleges and some universities.
The sound of electronic drums and cymbals themselves is heard by the drummer and possibly other musicians in close proximity, but even so, the foldback (audio monitor) system is usually fed from the electronic sounds rather than the live acoustic sounds. The drums can be heavily dampened (made to resonate less or subdue the sound), and their tuning and even quality is less critical in the latter scenario. In this way, much of the atmosphere of the live performance is retained in a large venue, but without some of the problems associated with purely microphone-amplified drums. Triggers and sensors can also be used in conjunction with conventional or built-in microphones. If some components of a kit prove more difficult to "mike" than others (e.g., an excessively "boomy" low tom), triggers may be used on only the more difficult instruments, balancing out a drummer's/band's sound in the mix.
Of our three picks, the Alesis Recital Pro is by far the easiest to use. All instrument selection is done with six buttons on the console (two sounds per button). Buttons for modulation, chorus, and reverb effects are provided, and there’s a display to show all the settings and parameters. Unlike our other picks, the Alesis’ metronome function can be adjusted anywhere from 30 to 280 BPM, with the speed shown on the display.
However, contemporary classical composers may also write for the bass guitar to get its unique sound, and in particular its precise and piercing attack and timbre. For example, Steve Reich, explaining his decision to score 2x5 for two bass guitars, stated that, "[With electric bass guitars] you can have interlocking bass lines, which on an acoustic bass, played pizzicato, would be mud."
Drums are used not only for their musical qualities, but also as a means of communication over great distances. The talking drums of Africa are used to imitate the tone patterns of spoken language. Throughout Sri Lankan history drums have been used for communication between the state and the community, and Sri Lankan drums have a history stretching back over 2500 years.
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.
