There are various types of Auto Accompaniment sections that
allow you to vary the arrangement of the accompaniment to
match the song you are playing. They are: Intro, Main (A, B),
Fill (A, B), and Ending. By switching among them during your
performance you can easily produce the dynamic elements of a
professional sounding arrangement in your performance.

How the chords are played or indicated with your left hand (in the

“ngering”. There are 2 types of ngerings as described below.
Chord Basics
A chord, in music, is any harmonic set of three or more notes that
is heard simultaneously. The most frequently encountered chords
are triads. A triad is a set of three notes that can be stacked in
thirds. When stacked in thirds, the triad’s members, from lowest
pitched tone to highest, are called: the Root, the Third, and the
Fifth.

Each style of the AK280 has been set with a default or standard tempo.
However, this can be changed by using the [TEMPO +]/[TEMPO –] button.
1. Use the [TEMPO +]/[TEMPO –] button to change the tempo. While
the tempo value is ashing, use the data dial to quickly change the
tempo.
2. Press the [TEMPO +] and [TEMPO –] buttons simultaneously to
restore the default tempo setting.
Note:
When style stops, changing the style will automatically reset the tempo.
However, changing the style during style playback will not result in tempo
change.
Chord Inversion
This chord is dened by the fact that its root is not in the bass (i.e. is not
in the lowest note). When the root is in the bass, we call the chord “Root–
Position Chord”. If we put the Third and Fifth in the root position, then it
forms “Inversion”. We call this chord “Inversion Chord”.
See the major triad diagram and its inverted chord to the right.
Chord Name
The chord name contains two parts: Chord root and Chord type.
Single–Finger
Single nger type not only can detect single nger but also can detect
multi nger. The single nger makes it easier to play chords through
only one, two or three keys including major, minor, seventh, and minor
seventh chord. Refer to relevant picture on the right for details.
Multi–Finger
Multi–nger allows you to play chords in normal ngering. Try playing the
32 chord types in C scale as listed on the right.
Note:
In full range mode, the entire keyboard will only recognice chords played
in normal ngering.
Triad Type
There are the following basic triad types:
TEMPO
Major Triad A root with a major third added above and a perfect fth
will consist as a “Major Triad”.
Minor Triad A root with a minor third added above and a perfect
fth will consist as a “Minor Triad”.
Augmented
Triad
A root with a major third added above and an
augmented fth will consist as an “Augmented Triad”.
Diminished
Triad
A root with a minor third added above and a diminished
fth will consist as a “Diminished Triad”.
