Roland KF-90 Manual Do Utilizador

A chord is a group of notes played at the same time. The pitch of the note 
that forms the base (the root note) is shown by a letter, and the type of 
constituent notes is shown by the chord type.

For instance, the chord “C Maj” has C (do) as the root note, and “Maj” (major) 
as the chord type. C Maj is composed of the three notes “C,” “E,” and “G.”

The root notes of chords are all indicated by a letter of the alphabet,   

(sharp) and   (flat), which correspond as follows.

“Chord Intelligence” is a feature that intelligently decides on 
accompaniment chords the moment you play a key (root note) specifying a 
chord during automatic accompaniment.

To play a C Maj chord, for example, you usually have to finger the three 
keys C, E, and G; but with Chord Intelligence, you only have to press the C 
key to initiate a C Maj chord accompaniment.
