Yamaha PSR-270 Using Auto Accompaniment Multi Fingering, Single Finger Chords, Fingered Chords

AUTO ACCOMPANIMENT — THE STYLE MODE

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 key of C is used here as an example; other keys follow the same rules. For example, Bb7 is played as Bb and A.)
