Using Auto Accompaniment - Multi Fingering; Single Finger Chords; Fingered Chords - Yamaha PSR-195 PSR-79 Manual

Using Auto Accompaniment — Multi Fingering
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 accompa-
niment by playing keys in the ACMP 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

Chords that can be produced in Single Finger
operation are major, minor, seventh and minor
seventh. The illustration below shows how to
produce the four chord types. (The key of C is
used here as an example; other keys follow the
same rules. For example, Bb7 is played as Bb
and A.)

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.
Fingered Chords in the Key of C
NOTE:
If the chord is inverted (i.e., C-E-G is played as G-C-E), the
PortaTone will still recognize it as a C chord. The chord
recognition system also has the following rules and excep-
tions:
• Minor 6th chords are recognized only in root position,
however; all other inversions are interpreted as minor 7th/
flatted 5th.
• If augmented and diminished 7th chords are inverted,
the lowest note will be recognized as the root.
• 7th flatted 5th chords may be played with the lowest
note as the root or the flatted 7th.
• Augmented 7th and diminished 7th chords are inter-
preted as simple augmented and diminished.
NOTE:
The following chords are not recognized : B minor 6, Bb minor
6, and B augmented.
