A) Single Finger Chords - Yamaha PSS-680 PortaSound Authorized Product Manual

A) Single Finger Chords
Press the AUTO ACCOMPANIMENT SINGLE FINGER
MODE selector (3a) to turn on the Single Finger mode. (The
rhythm must be off.) Now play single keys in the AUTO
ACCOMPANIMENT SECTION (19) of the keyboard with
one finger and notice how the PortaSound produces complete
major chords instead of just single notes.
In the Single Finger mode, the PortaSound PSS-680 can play
the following four different types of chords, depending on
the key combinations you press in the AUTO ACCOMPA-
NIMENT SECTION (19).
MAJOR CHORDS: To obtain a certain major chord. all you
have to do is press the key corresponding to its basic
note. For example, if you want to hear a C major chord,
press C.
MINOR CHORDS: Minor chords are produced by pressing
the basic note together with any black key to the left
of it. The illustration below shows how to play a C minor
chord.
SEVENTH CHORDS: To obtain a seventh chord, press the
basic note along with any white key to its left.
MINOR SEVENTH CHORDS: Minor seventh chords are
produced by pressing the basic note together with any
black key AND white key to the left of it.
Note:
In general, you should release the keys completely, lifting
you fingers off the keyboard, to change to a different chord
with the Single Finger Chord function. Otherwise, you
may not be able to obtain the intended type of chord.
For example, if you want to change from G major to A
major and do not release the G key completely before
pressing A, you will get an A seventh chord instead of the
A major chord you wanted.
On the other hand, you can for example change from a
major to a minor chord while pressing the basic note by
additionally playing any black key to the left. This gives
a different effect than you would achieve by releasing the
basic key. (Of course, this way of altering chords will not
work when switching to chords using fewer keys than the
current chord, say from C minor seventh to C seventh.)
TIP: The PortaSound PSS-680 plays Single Finger Chords
with a large variety of different instruments, depending
on the currently selected style. This allows you to choose
the best kind of accompaniment voices for the music
you want to play.
To see how important it is to choose the right kind of voice
and accompaniment sounds, try playing Mendelssohn's fa-
mous "Wedding March", following the score below.
First, select a suitable voice, e.g. number 29 (SMALL
CHURCH organ) or 16 (TROMBONE), then a style that
fits in with it. For example, style 03 (GOSPEL) gives an organ
accompaniment, while MARCH 1 and 2 (77, 78) provide brass
sections.
Next, turn on the Single Finger Chord function by pressing
SINGLE FINGER. You can now perform the "Wedding
March" by playing the melody with your right hand and the
chords indicated above the score with your left.
(Remember: "Am" means an A minor chord, "B7" a B seventh
chord, and so on.)
