Playing Style (Accompaniment) Chords

PSR-450 Owner’s Manual

■ About chords

Playing two or more notes together simultaneously creates a “chord.”

Playing a note together with two other notes spaced three notes (steps) apart — such as

the notes C, E and G — creates a harmonious sound. Chords like these are called “triads”

and they play an important role in most music.

Taking the chord above as an example, the lowest note of this triad is called the “root note.” This is the central note

sound, and it supports or anchors the rest of the notes chord.

You’ll notice that the middle note of the chord above (E) is the third step in the succession of scale notes — C, D,

then E. There are two types of “thirds” in chords: major thirds and minor thirds.

We’ll also alter the top note of our original chord and make three additional chords, as shown below. (The captions

indicate the intervals between each of the notes.)

The basic characteristics of the chord sound are same, no matter if we change the order of the notes from bottom to

top, or if we add other same name notes in different octaves. Beautiful sounding harmonies can be built in this man-

ner, and emotional music can be created by playing different chords one after the other according to commonly

accepted rules. Harmony determines the nature of chords, and music is created based on harmony.

● Chord names

From the chord name, you can tell at a glance what type of chord it is and which notes

make up the chord. Understanding the basic structure of chords is very useful — once

you’re familiar with this, you’ll be quickly and easily play chords by looking at the

names that appear above the notation.

● Chord types (These chords are among those that can be recognized by the Fingered method.)
