The Hammond organ is an electric organ invented by Laurens Hammond and John M. Hanert and first manufactured in 1935. Multiple models have been produced, most of which use sliding drawbars to vary sounds. Until 1975, Hammond organs generated sound by creating an electric current from rotating a metal tonewheel near an electromagnetic pickup, and then strengthening the signal with an amplifier to drive a speaker cabinet. The organ is commonly used with the Leslie speaker.
The piano is a keyboard instrument that produces sound when pressed on the keys. Most modern pianos have a row of 88 black and white keys: 52 white keys for the notes of the C major scale and 36 shorter black keys raised above the white keys and set further back, for sharps and flats. This means that the piano can play 88 different pitches, spanning a range of a bit over seven octaves. The black keys are for the "accidentals", which are needed to play in all twelve keys.
A digital piano is a type of electronic keyboard instrument designed to serve primarily as an alternative to the traditional acoustic piano, both in how it feels to play and in the sound it produces. Digital pianos use either synthesized emulation or recorded samples of an acoustic piano, which are played through one or more internal loudspeakers. They also incorporate weighted keys, which recreate the feel of an acoustic piano. Some digital pianos are designed to also look like an upright or grand piano. Others may be very simple, without a stand.
An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument based on keyboard instruments. Electronic keyboards include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. In technical terms, an electronic keyboard is a synthesizer with a low-wattage power amplifier and small loudspeakers.
The Yamaha CS-80 is an analog synthesizer released in 1977. It supports true 8-voice polyphony, with two independent synthesizer layers per voice each with its own set of front panel controls, in addition to a number of hardwired preset voice settings and four parameter settings stores based on banks of subminiature potentiometers.
Electone is the trademark used for electronic organs produced by Yamaha. With the exception of the top end performance models, most Electones are based on the design of the spinet electronic organ. Current models are completely digital and contain a variety of sounds, effects, and accompaniments, on top of the ability to store programming data onto memory devices.
Keyboard expression is the ability of a keyboard musical instrument to change tone or other qualities of the sound in response to velocity, pressure or other variations in how the performer depresses the keys of the musical keyboard. Expression types include:
A stage piano is an electronic musical instrument designed for use in live performances on stage or in a studio, as well as for music recording in Jazz and popular music. While stage pianos share some of the same features as digital pianos designed for home use and synthesizers, they have a number of features which set them apart. Stage pianos usually provide a smaller number of sounds, with these being of higher quality than the ones found on regular digital pianos and home synthesizers.
The Yamaha Motif is a series of music workstation synthesizers, first released by Yamaha Corporation in August 2001. The Motif replaced the EX series in Yamaha's line-up and was also based on the early Yamaha S series. Other workstations in the same class are the Korg Kronos and the Roland Fantom G. The series' successor is Yamaha Montage.
The Wurlitzer electronic piano is an electric piano manufactured and marketed by Wurlitzer from 1954 to 1983. Sound is generated by striking a metal reed with a hammer, which induces an electric current in a pickup. It is conceptually similar to the Rhodes piano, though the sound is different.
The electric grand piano is a stringed musical instrument played using a keyboard, in which the vibration of strings struck by hammers is converted by pickups into electrical signals, analogous to the electric guitar's electrification of the traditional guitar.
The Yamaha P-120 is a portable electronic piano, released in 2002. The 88-key so-called "GH" keyboard is action-weighted, imitating the feel of a real piano. It includes several sample keyboard sounds, such as harpsichord, clavichord, vibraphone, guitar and more. Basic sequencing and editing are built-in.
The Yamaha Music SynthesizerS90 is a synthesizer and a MIDI controller in one unit, released in 2002 to supersede the S80. As such, it is part of the S series together with the S03 and S08. It was superseded by the S90ES in 2005, itself superseded by the S90XS in 2009.
The Yamaha P-85 is an entry-level digital piano introduced in 2007. It is the successor of the Yamaha P-70 and introduces a MIDI sequencer.
The Korg CX-3 is an electronic clonewheel organ with drawbars that simulates the sound of an electromechanical Hammond organ and the Leslie speaker, a rotating speaker effect unit. The CX-3 was first introduced in 1979.
The Yamaha PSR-E323, also known as the YPT-320, is an electronic keyboard manufactured by the Yamaha Corporation in 2009. It is a basic home keyboard intended for learning and personal use.
The Yamaha DX21 is a digital controlled bi-timbral programmable digital FM synthesizer with a four operator synth voice generator which was released in 1985. It uses sine wave-based frequency modulation (FM) synthesis. It has two FM tone generators and a 32-voice random-access memory (RAM), 32 user voices and 128 read-only memory (ROM) factory preset sounds. As a programmable synth, it enables users to create their own unique synthesized tones and sound effects by using the algorithms and oscillators. The instrument weighs 8 kg (17.6 lbs). On its release, it sold for $795.
The Yamaha P-125 is a portable digital piano introduced in 2006. It replaces its predecessor, the P-115.
Yamaha CP88 and Yamaha CP73 are professional stage pianos produced by Yamaha. These instruments are identical except for keyboard action and size. The instruments are designed to be played at live concerts on the stage, and are also suitable for recording studios due to their versatility of sound. As they are intended for professional use in locations with a preinstalled sound system, such as concert venues and recording studios, they do not have internal speakers, like the home instruments.
