The Apple Keyboard is a keyboard designed by Apple Inc. first for the Apple line, then the Macintosh line of computers. Dozens of models have been released over time, including the Apple Extended Keyboard. Currently, Apple offers only three keyboards via Bluetooth: Magic Keyboard (silver only), and Magic Keyboard with Numeric Keypad (silver or space gray). The space gray model is also included with the iMac Pro.
A wireless keyboard is a computer keyboard that allows the user to communicate with computers, tablets, or laptops with the help of radio frequency (RF), infrared (IR) or Bluetooth technology. It is common for wireless keyboards available these days to be accompanied by a wireless mouse.
The harpsichord concertos, BWV 1052–1065, are concertos for harpsichord, strings and continuo by Johann Sebastian Bach. There are seven complete concertos for a single harpsichord (BWV 1052–1058), three concertos for two harpsichords (BWV 1060–1062), two concertos for three harpsichords (BWV 1063 and 1064), and one concerto for four harpsichords (BWV 1065). Two other concertos include solo harpsichord parts: the concerto BWV 1044, which has solo parts for harpsichord, violin and flute, and Brandenburg Concerto No. 5 in D major, with the same scoring. In addition, there is a nine-bar concerto fragment for harpsichord (BWV 1059) which adds an oboe to the strings and continuo.
The Dvorak Simplified Keyboard(/d(ə)ˈvɔːræk/ ( listen ) d(ə)-VOR-ak ) is a keyboard layout patented in 1936 by August Dvorak and his brother-in-law, William Dealey. Several modifications have since been designed by the team directed by Dvorak or by ANSI. These variations have been collectively or individually termed the Simplified Keyboard or American Simplified Keyboard, but they all have come to be known commonly as the Dvorak keyboard or Dvorak layout.
The Partitas, BWV 825–830, are a set of six harpsichord suites written by Johann Sebastian Bach, published individually beginning in 1726, then together as Clavier-Übung I in 1731, the first of his works to be published under his own direction. They were, however, among the last of his keyboard suites to be composed, the others being the six English Suites, BWV 806-811 and the six French Suites, BWV 812-817, as well as the Overture in the French style, BWV 831.
A keyboard amplifier is a powered electronic amplifier and loudspeaker in a wooden speaker cabinet used for amplification of electronic keyboard instruments. Keyboard amplifiers are distinct from other types of amplification systems such as guitar amplifiers due to the particular challenges associated with making keyboards sound louder on stage; namely, to provide solid low-frequency sound reproduction for the deep basslines which keyboards can play and crisp high-frequency sound for the high-register notes. Another difference between keyboard amplifiers and guitar/bass amplifiers is that keyboard amps are usually designed with a relatively flat frequency response and low distortion. In contrast, many guitar and bass amp designers purposely make their amplifiers modify the frequency response, typically to "roll off" very high frequencies, and most rock and blues guitar amps, and since the 1980s and 1990s, even many bass amps are designed to add distortion or overdrive to the instrument tone (for bass, this is called "fuzz bass ").
The Apple Wireless Keyboard is a wireless keyboard built for Macintosh computers and compatible with iOS devices. It interacts over Bluetooth wireless technology and unlike its wired version, it has no USB connectors or ports. Both generations have low-power features when not in use. It was discontinued on October 13, 2015, and was succeeded by the new Magic Keyboard.
