AUTO ACCOMPANIMENT - THE STYLE MODE USING AUTO ACCOMPANIMENT - MULTI FINGERING When it is set to on (page 52), the auto accompaniment function automatically generates bass and chord accompaniment for you to play along with, by using Multi Fingering operation. You can change the chords of the accompaniment by playing keys in the auto accompaniment section of the keyboard using either the "Single Finger" or "Fingered" method. With Single Finger you can simply play a one-, two- or three-finger chord indication (see Single Finger Chords below). The Fingered technique is that of conventionally playing all the notes of the chord. Whichever method you use, the PortaTone "understands" what chord you indicate and then automatically generates the accompaniment. Single Finger Chords C Chords that can be produced in Single Finger To play a major chord: Press the root note of the chord. operation are major, minor, seventh and minor seventh.

Fingered Chords
Using the key of C as an example, the chart below shows the types of
chords that can be recognized in the Fingered mode.
* Notes enclosed in parentheses are optional; the chords will be recognized without them.
USING AUTO ACCOMPANIMENT — MULTI FINGERING
When it is set to on (page 52), the auto accompaniment function automati-
cally generates bass and chord accompaniment for you to play along with,
by using Multi Fingering operation.
You can change the chords of the
accompaniment by playing keys in the auto accompaniment section of the
keyboard using either the “Single Finger” or “Fingered” method.
With
Single Finger you can simply play a one-, two- or three-finger chord indica-
tion (see Single Finger Chords below).
The Fingered technique is that of
conventionally playing all the notes of the chord.
Whichever method you
use, the PortaTone “understands” what chord you indicate and then
automatically generates the accompaniment.
Single Finger Chords
Chords that can be produced in Single Finger
operation are major, minor, seventh and
minor seventh.
The illustration shows how to
produce the four chord types.

the same rules.
For example, B
