11 Glossary

This glossary provides basic definitions of terms used frequently in Disklavier manuals.

Clavinova™

A series of Yamaha digital pianos.

Continuous Pedal

See “Incremental Pedal”.

Incremental Pedal

Piano pedals are not always completely up or down and may be held somewhere in-between. Using incremental pedal data (also called continuous or half pedal data) the Disklavier precisely records the up and down movement of the piano pedals.

Ensemble Song

A song which contains piano parts and accompanying instrumental voices. An Ensemble song contains the same left and right-hand parts as an L/R song, and in addition, up to 13 accompanying instrument tracks. These extra tracks are played by the internal XG tone generator. The accompanying tracks may be used for acoustic bass, drums, strings, vibes, etc.

E-SEQ Song Format

A song file format developed by Yamaha for saving songs.

L/R Song

In a L/R song, the left-hand piano part is stored on track 1 (L) and the right-hand piano part is stored on track 2

(R). During playback you can cancel either part, and then play that part yourself. When recording an L/R song, you can record the two parts simultaneously or separately.

MIDI

An acronym for Musical Instrument Digital Interface. MIDI allows electronic musical instruments to communicate with each other.

Floppy Disk

The magnetic storage medium that the Disklavier uses to save songs. The Disklavier uses the 3.5 inch 2DD and 2HD floppy disks commonly used for computers.

General MIDI (GM)

An addition to the MIDI standard that simplifies the transfer of MIDI song files between instruments of different manufacturers. A MIDI song recorded using a GM compatible tone generator should play back correctly when used with any GM compatible tone generator. The standard specifies that a GM compatible tone generator must support 24-note polyphony, 16 parts, and 128 standard voices.

Half Pedal

See “Incremental Pedal”.

Piano Parts

Refers to the left- and right-hand piano parts of a song. The left-hand piano part is recorded onto track 1 and the right-hand piano part is recorded onto track 2. These track assignments are the default settings and can be changed.

PianoSoft™

The PianoSoft Disk Collection is a library of prerecorded song disks made by Yamaha specifically for use with the Disklavier.

PianoSoft·Plus™

PianoSoft·Plus disks contain Ensemble songs that can be played on the Disklavier.

Polyphony

piano specifications

Yamaha pianos are renowned for their exceptional quality, rich sound, and innovative technologies, making them a popular choice among musicians and music enthusiasts. With a history dating back to 1887, Yamaha has continually evolved its piano designs to meet the needs of players across genres and skill levels.

One of the main features that sets Yamaha pianos apart is their diverse range of models, which includes acoustic, digital, and hybrid pianos. Acoustic pianos, such as the popular C-series grand pianos, are constructed with high-quality woods and materials, providing a traditional playing experience characterized by a rich tonal palette and impressive resonance. The YDP series of digital pianos incorporates advanced features while maintaining a traditional aesthetic, making them ideal for home use.

Yamaha's dedication to innovation is evident in its digital pianos, which boast cutting-edge technology. The Real Grand Expression (RGE) technology in premium models ensures an authentic touch and sound experience, closely mimicking that of an acoustic piano. The Graded Hammer Standard (GHS) action emulates the heavier touch of lower keys and lighter touch in higher keys, allowing players to develop proper finger technique.

Another notable technology found in Yamaha pianos is the Intelligent Acoustic Control (IAC), which optimizes sound output at various volume levels. This feature ensures that the piano sounds full and balanced whether played quietly or at concert levels. Additionally, the Acoustic Optimizer improves sound projection and tonal clarity, delivering a more immersive playing experience.

For those who seek an interactive learning experience, Yamaha integrates educational features in its digital models. The Smart Chord and Smart Pianist app allows users to explore new songs and practice effectively, making it easier for beginners to learn and understand music theory.

Yamaha pianos are also designed with durability and craftsmanship in mind. The use of premium materials and precise manufacturing processes ensures that each instrument not only sounds incredible but is built to last. This commitment to quality and performance makes Yamaha pianos a trusted choice for aspiring musicians and seasoned professionals alike.

Ultimately, whether you’re looking for an elegant acoustic instrument or a technologically advanced digital piano, Yamaha offers a wide selection that meets the needs of every player, combining tradition with innovation to create instruments that inspire creativity and passion for music.
